Welcome to Svitgrid

Your solar inverter already knows everything: how much the sun is making, how full the battery is, whether the grid is up. It just keeps it to itself, on a small screen in a cupboard.

Svitgrid reads that information and puts it on your phone. Then it goes further — it can tell the inverter what to do, on a schedule you set.

What Svitgrid does

• Shows you live power. Solar, battery, grid and house, updating while you watch.
• Keeps the history. Days, weeks, months and years, so you can compare this January with last January.
• Counts the money. What you paid the grid, what the grid paid you, what your green tariff earned.
• Predicts tomorrow. A solar forecast built from your roof's real angle and the weather.
• Runs your inverter for you. Charge the battery when power is cheap. Sell when it is expensive. Fill the battery before a scheduled blackout.
• Tells you when something breaks. A dead string, an offline inverter, a battery heading for empty.

What Svitgrid is not

Who it is for

Anyone with a compatible solar inverter — see Supported inverters. Most of Svitgrid's users are in Ukraine, so it also understands Ukrainian electricity tariffs and blackout schedules. The rest of the app works anywhere.

How to read these docs

Each page starts with an In short box. If that answers your question, you are done. Under it is the step-by-step. Grey More detail boxes hold the exhaustive version — open them only when you need the exact numbers.

How Svitgrid works

Your inverter is not on the internet. It sits on your home Wi‑Fi and answers questions from anything on the same network.

So Svitgrid needs a collector — something at home that asks the inverter for numbers and forwards them to the Svitgrid cloud. Your phone then reads them from the cloud, wherever you are.

  inverter  ──►  collector  ──►  Svitgrid cloud  ──►  your phone
 (your home)   (your home)         (internet)         (anywhere)

Everything else in Svitgrid — charts, money, forecasts, schedules — is built on that one flow. Which collector you pick decides how complete your data is.

The three collectors

Why gaps matter

A collector that only runs sometimes does not just lose those hours — it quietly ruins the numbers built on them. Your daily total is short, your solar forecast learns from an incomplete picture, and a scheduled event cannot run if nothing is at home to run it.

What happens in the cloud

The cloud stores your readings, adds up daily and monthly totals, prices them against your tariff, runs the forecast, and decides when a scheduled event should fire. It also sends your notifications.

Download and install

iPhone and iPad

1. Open the App Store.
2. Search for Svitgrid.
3. Tap Get.

Requires iOS 15 or newer.

Android

1. Open Google Play.
2. Search for Svitgrid.
3. Tap Install.

Requires Android 7 or newer.

Permissions Svitgrid asks for

Svitgrid asks for each of these only when it first needs it, and explains why at the time. You can refuse any of them and the rest of the app keeps working.

Keeping the app up to date

Turn on automatic updates. Svitgrid changes quickly, and some fixes need both the app and the server. If your app is far too old to work correctly, Svitgrid blocks it on launch and asks you to update — that screen means your version is no longer supported, not that something is broken.

Create your account

Register

1. Open Svitgrid and tap Create account.
2. Enter your email and a password of at least 8 characters.
3. We email you a 6-digit code. Type it into the app to confirm your address.

Sign in with Google or Apple

Faster, and there is no password to forget. Use the same one every time — signing in with Google and then later with email creates two separate accounts, and your home will only be in one of them.

Forgotten password

Tap Forgot password on the sign-in screen. We email you a 6-digit code; type it in and choose a new password.

Two-factor authentication

Under Settings → Account → Security you can require a second code at sign-in. Turn this on if other people can reach your email.

Deleting your account

Settings → Account, then the danger zone at the bottom. This removes your account and the homes you own. It cannot be undone.

Setting up your system

The first time you sign in, Svitgrid asks a series of questions. None of it is permanent — every answer can be changed later in Settings.

Step 1 — Name your home

Anything you like: Home, Dacha, Mum's house. If you look after more than one property, the name is how you tell them apart.

You also pick a picture for the house — a cottage, an apartment block, a ground-mounted array with no building at all. It appears on your dashboard behind the weather.

Step 2 — Where it is

Used for two things: the solar forecast needs to know where the sun will be, and Ukrainian blackout schedules are organised by region.

Let the app use your location, or type the address.

Step 3 — How data is collected

Choose your collector — this is the choice explained in How Svitgrid works.

• This phone — free, works immediately, only collects while you are home with the app open.
• Svitgrid Gateway — a small box that collects 24/7.
• Home Assistant — if you already run it.

Step 4 — Your inverter

Pick the brand, then the model. Svitgrid supports 80 models across 18 brands — see Supported inverters.

Step 5 — Connecting to the inverter

What Svitgrid needs here depends on the brand. Most commonly it is the inverter's IP address on your home network plus the serial number of the Wi‑Fi logger stick plugged into it. Some brands need neither. See Connecting to your inverter for how to find both.

Svitgrid can usually find the inverter by scanning the network, so try Scan before typing anything.

Step 6 — Battery and panels

Tell Svitgrid what you actually own:

• Battery — chemistry (usually LiFePO4), capacity in kWh, and whether two inverters share one battery bank.
• Panels — how many strings, their total kWp, which way they face and their tilt.

The panel answers feed the solar forecast. Rough numbers are fine; you can correct them later.

Step 7 — Pair the Gateway

Only if you chose the Gateway. Svitgrid finds it over Bluetooth, then asks for your Wi‑Fi name and password so the box can reach the internet on its own. See Svitgrid Gateway.

Step 8 — Check and finish

A summary of everything. Confirm, and the dashboard opens.

Dashboard

The dashboard is two pages. The first is the diagram; swipe up for your charts. Pull down anywhere to refresh.

The energy diagram

Four things surround your house, and lines connect them. Power travels along each line as a moving pulse, so you can see direction at a glance.

• Sun — what the panels are making right now.
• Battery — how full it is, and whether it is charging or draining.
• Grid — power coming in, or going out. Negative means you are exporting.
• House — what your home is using.

Tap any of the four to open a detail card with more context — including what today's grid import and export have actually cost or earned on your tariff.

The cards below

• Battery — charge level, power in or out, and how long it will last. The countdown stops at your inverter's own cut-off level, not at 0%, because that is when your house actually goes dark.
• Grid — voltage, import and export, priced for today.
• Solar — per-string output. Four or more strings fold into a compact grid.
• Generator port — only if your inverter has one in use. See Smart load and generator port.

On your home screen, outside the app

Svitgrid has a home-screen widget for Android and iOS showing live power without opening the app. The Android widget also has a refresh button.

Banners

Short messages above the diagram, each appearing only when it applies: firmware updating, data looks stale, battery not configured, a scheduled blackout is coming, solar is being curtailed because the battery is full and there is nowhere for the power to go.

Homes with several inverters

Svitgrid draws a diagram that fits however many inverters you have, and the totals are summed from exactly the inverters shown. A filter bar at the top lets you look at one inverter at a time, and a table view compares them side by side.

If two inverters share one physical battery bank, say so in Inverter settings — otherwise the same battery is counted twice.

How often it updates

New readings arrive as fast as your collector sends them, and that rate is a setting rather than a fixed speed. Look for Cloud reporting — "how often this system reports to the cloud" — on your collector's own screen: Harvest for a phone, Edge device for a Gateway, or Home Assistant. You can set anywhere from 30 seconds to 5 minutes.

The fastest step you may choose depends on your plan: 30 seconds on Plus and Pro, 60 seconds on Basic. A longer interval is gentler on a phone's battery and on your data allowance.

Battery

Open it by tapping the battery on the dashboard.

What you see

• State of charge — how full, as a percentage.
• Power — how fast it is charging or draining, in watts.
• Runtime — how long until it reaches your inverter's cut-off point at the current rate. Shown as "more than 48 hours" when the drain is very slow.
• Packs — one card per physical battery you own.
• Cells — per-cell voltages, if a battery monitor is connected.

Packs

If your installation has several batteries, each is a card. Give them names — Garage, Left rack — so a warning about one tells you which one to walk to.

Svitgrid compares what you configured against what the battery actually reports, and shows the disagreement on the card rather than silently trusting either.

Cells

With a battery monitor connected, Svitgrid shows every cell's voltage, the spread between the best and worst cell, temperatures, and whether the balancer is working. See Battery monitors for which monitors are supported and how to connect one.

The screen leads with a plain verdict — Battery is healthy, Cells are drifting apart, One cell is falling behind, Too cold to charge, Readings cannot be trusted.

Charts and reports

Reached from the Charts tab. Two sub-tabs: Overview and Finance.

Choosing a period

Week · This month · Last month · Year · or a custom range. Everything on both tabs follows the period you pick.

Overview

• Totals — generated, consumed, imported, exported for the period.
• Where your power came from — solar, battery and grid as a split bar.
• Production heatmap — a grid of days and hours. A genuinely zero hour and an hour where nothing was collected are drawn differently, so a gap in your data never masquerades as a night.
• Hourly profile — for today, the shape of the day so far.
• Battery charge curve — how full the battery was across the period.
• Change vs the period before — this week against last week.

Finance

• What you paid the grid, on your real tariff including day and night zones.
• What you earned exporting.
• Green tariff settlement — the month it covers, and what it worked out to.
• Savings — what the solar system saved you against buying everything from the grid.

All of it depends on having your tariff set up correctly. See Electricity tariff.

Compare

Puts this period next to the previous one: generated, consumed, imported, exported, peak solar, peak load, net saving.

Export to CSV

Writes the selected period to a spreadsheet file you can open in Excel or send to your accountant.

Full-screen display

Open it from the dashboard and rotate the device.

You get one large gauge and four tiles — Solar, Battery, Grid, House — in type big enough to read across a room. Under Solar, each panel string's voltage and current is listed.

There is also a full-screen forecast strip, reached the same way from the Solar forecast screen, which you can pan across several days.

Notifications and alerts

The alerts you can get

Every alert explains itself

Tapping an alert opens a page that shows the evidence — the actual battery level next to the threshold it crossed, how long the equipment has been silent, the day's total. Not a field name and a number.

Underneath is What you can do: concrete one-tap actions. A low battery on a two-zone meter, for example, offers to charge tonight instead of now, and shows you both prices before you agree.

Settings

Settings → Notifications.

• Per-category switches — mute the ones you do not care about.
• Daily summary — off by default, with a time you choose.
• Weekly summary — off by default, Mondays.
• Quiet hours — off by default, 22:00 to 07:00 when on.
• Monthly value report — on by default.
• Product updates — on by default.

Not getting notifications?

1. Check the master switch in your phone's own settings, not just Svitgrid's.
2. Check the category is not muted.
3. Check quiet hours.
4. On Android, check battery optimisation is not suspending Svitgrid.

Solar forecast

Open it from the Forecast button in the bottom bar.

What you see

• Today's curve with a shaded band around it. The band is the uncertainty: narrow means confident, wide means the weather could go either way.
• The next few days as a strip you can tap through.
• How accurate we have been — yesterday's forecast against what actually happened.
• Unrealised generation — power your panels could have made but did not, usually because the battery was full and there was nowhere to put it.
• Battery outlook — hourly bars showing where your charge is heading.

Turn the phone sideways for a full-screen strip you can pan across several days.

How it works

Svitgrid combines the weather forecast for your exact location with what it knows about your system: how many kilowatts of panels, which way they face, their tilt, and how they have actually behaved on similar days.

That last part matters most. The forecast learns from your roof. A system with a tree shading it at 4pm will, after a couple of weeks, have that dip built into its prediction.

Making it accurate

Check Settings → Inverter settings → Solar configuration:

• kWp — total panel power. On the panel label, multiply the watts by how many you have.
• Azimuth — the compass direction the panels face. South is 180°. There is a compass tool: stand facing the same way as the panels and read it off.
• Tilt — the angle from flat. A typical pitched roof is 30–35°.

Set each string separately if they face different ways.

Calendar and daily planner

Open the Calendar tab.

The calendar

A week strip at the top, and below it an hour-by-hour timeline of the day. You can lay your battery level, grid flow and export over the timeline, and — in Ukraine — the day-ahead electricity price.

Each coloured block is a scheduled event. Tap it to see what it did and what actually happened.

The daily planner

Rather than building a schedule by hand, let Svitgrid propose one each day. It looks at tomorrow's solar forecast, your tariff, your battery, and any scheduled blackout, and drafts a plan.

You approve it before anything runs. The plan review screen lists each proposed window, why it is there, and the limits it will respect.

Planning styles

Authorising the planner

Because the planner writes to your inverter, it needs explicit permission. You will be asked once to authorise daily planning, which creates a signing key on your device. Without it, the planner can suggest but never act.

Planner activity

A log of every decision the planner made and every command it sent — useful for understanding why your battery did something unexpected.

Creating a calendar event

Tap + on the Calendar tab.

Choose what the event does

Set the time window

Start and end time, then how it repeats — once, daily, weekly on chosen days, or a custom pattern. You can also give it a start and end date.

Set the details

Each mode has its own options. The common ones:

• Charge battery — where the power comes from (solar / surplus / grid / both), the target charge level, and a maximum charging power. There is also a switch to suspend your inverter's own time-of-use schedule while the event runs, so the two do not fight.
• Sell to grid — a minimum battery level to protect, a maximum export power, and in Ukraine a minimum price below which it will not sell.
• Start generator — the charge level that starts it, the level that stops it, quiet hours, minimum run and rest times, and whether it should only run when the grid is actually down.
• Professional — up to eight conditions and eight actions. Conditions can test battery level, solar power, house load, whether the grid is up, whether a blackout is scheduled, the day's forecast, or the market price.

What happens when it runs

At the start time, Svitgrid sends the commands to your inverter and notifies you. At the end, it puts the previous settings back and notifies you again.

Time-of-use explained

Hybrid inverters have a time-of-use table burned into their own settings — typically six slots covering the whole 24 hours. Each slot says: until this time, aim for this battery level, and may you charge from the grid.

The inverter follows this table by itself, with no phone, no internet and no Svitgrid. That is why it keeps working when everything else fails.

What Svitgrid does with it

When you create a calendar event, Svitgrid translates it into changes to those slots, sends them to the inverter, and puts the old values back afterwards.

Where to see it

Settings → Inverter controls → Time-of-use. You can edit the slots directly if you prefer to manage your own schedule.

Blackout schedule

Setting it up

Settings → Household settings:

1. Region — your oblast.
2. Group — your queue number, printed on your electricity bill or on your supplier's website.
3. Advance warning — how long before an outage you want to be told: off, or 1, 2, 3 or 6 hours. The default is 1 hour.

What you see

A strip on the dashboard showing today's and tomorrow's scheduled outages for your group, with a coloured dot for the current state.

What Svitgrid does about it

• Warns you at the notice period you chose.
• Tells you if your battery is too low to cover the coming outage.
• Can fill the battery first, if you create a charge event or use the Survive outages planning style.
• Can suppress other events during an outage, so a "sell to grid" window does not fight a blackout.

Supported inverters

There are two different questions, and the answer is not the same:

• Can Svitgrid read my inverter? For everything in the table below, yes — live power, history, charts, money, forecast, alerts.
• Can Svitgrid control my inverter? Only Deye, Sunsynk and Sol-Ark. Everything else is read-only.

All supported brands

How well each model is proven

Support for a model means Svitgrid knows where that inverter keeps its numbers. For the long-standing Deye and Sunsynk models that mapping has been checked against real hardware many times over. For several of the brands added recently it comes from the manufacturer's documentation and has been confirmed on few units — or, in a couple of cases, none yet.

Not on the list?

Email hello@svitgrid.app with the make, model and a photo of the label. Adding a brand means mapping its registers, which needs either documentation or access to a real unit.

Connecting to your inverter

What you need

The IP address. Every device on your home network has one, like 192.168.1.50. Svitgrid can usually find it by scanning — try Scan first.

The logger serial. Most inverters talk through a small Wi‑Fi "logger" or "data stick" plugged into their side. It has a serial number, usually 10 digits, and Svitgrid needs it to address the inverter correctly.

Finding the IP address

Easiest — tap Scan in Svitgrid and let it look.

From your router — open your router's admin page and find the connected-devices list. The logger usually appears with a name containing the brand or a long number.

From the logger's own page — many loggers publish a small web page on their own address.

Finding the logger serial

It is printed on the logger's own label — the small box plugged into the inverter, not the inverter's main nameplate. It is also usually shown in the manufacturer's own app.

Testing the connection

Svitgrid tests as soon as you enter the details. If it fails, it tells you which part failed rather than just "error":

• Could not connect — wrong IP address, or the inverter is on a different network from your phone.
• Connected but no answer — usually the wrong logger serial.
• Answered with nonsense — usually the wrong model selected.

See Troubleshooting.

Requirements

• The collector and the inverter must be on the same network. Guest Wi‑Fi is a different network. So is a 2.4 GHz network isolated from the 5 GHz one on some routers.
• The manufacturer's app may need to be closed — many loggers accept only one connection at a time.

Inverter settings and controls

Both are under Settings, and both need owner or admin rights.

Inverter settings — describing your system

This is where you tell Svitgrid what you own. Getting it right matters, because the forecast, the money and the battery warnings are all built on it.

• Model, IP address, logger serial, phases
• Battery — chemistry, capacity, cells in series, and whether this inverter shares a battery bank with another
• Solar — strings, kWp, tilt, azimuth
• Generator port and smart load
• Power calibration — a correction factor, if your inverter reports a value at the wrong scale
• Daily write limit — a cap on how many commands per day Svitgrid may send
• Transfer collection to another phone — see Moving collection

Inverter controls — changing the inverter

Adding another inverter

Settings → Add inverter, then the same steps as the first one: model, connection, battery, panels.

Because the household already exists, you are not asked about location or collector again.

Parallel systems

If your inverters are wired in parallel, you will also be asked about topology — which is the master and which are slaves.

How many are allowed

Your plan sets a limit — see Plans and subscription.

Smart load and generator port

What the port is

A spare AC terminal on the inverter, used in one of two ways:

• Generator input — a petrol or diesel generator feeds the inverter.
• Smart load output — a load the inverter can switch on when there is surplus power, typically a water heater.

Turning it on in Svitgrid

Settings → Inverter settings → Generator port. Choose which way you use it and switch on Show generator port.

What you see once it is on

A generator-port node on the dashboard diagram, a detail card with runtime and fuel figures, and its own series in the charts.

Controlling it

On Deye, Sunsynk and Sol-Ark you can force the generator to start from Inverter controls, or schedule it with a Start generator calendar event — including start and stop charge levels, quiet hours, and a rule that it only runs when the grid is actually down.

Svitgrid Gateway

Sold as the Svitgrid Gateway, 999 ₴. The compliance label on the underside calls it ED-1 — same device.

Why you would want one

Your phone can only read the inverter while you are home with the app open. The Gateway never stops. It also does things a phone cannot:

• Collects 24/7, including overnight and while you are away
• Runs your scheduled events even when nobody is home
• Talks to Zigbee smart sockets and EV chargers
• Reads a battery BMS continuously

Setting one up

1. Plug it in near the inverter, within reach of your Wi‑Fi.
2. In Svitgrid, go to Settings → Edge devices → Add device.
3. Svitgrid finds it over Bluetooth.
4. Give it your Wi‑Fi name and password.
5. It connects and starts collecting.

The status light

The button

Managing it

Settings → Edge devices, then tap the device:

• Uptime, firmware version and signal strength
• Pause / resume monitoring
• Reboot
• Factory reset
• Replace with a new unit, keeping your history
• Remove

It beeps

The Gateway plays a short melody each time it successfully applies a battery-charge command from the cloud. On a busy schedule this can be many times an hour.

Installing Gateway firmware

Most people never need this. A Gateway bought from Svitgrid arrives ready to use and updates itself.

What you need

• A Chromium-based browser — Chrome, Edge or Opera. Safari and Firefox cannot talk to USB devices.
• A data USB-C cable. Many charging cables have no data wires and will simply not show the device.
• A direct USB port, not a hub.

Steps

1. Plug the device into your computer.
2. Open svitgrid.app/flash.
3. Click the button and pick your device from the list.
4. Wait about 30 seconds without unplugging.

Watching what it does

svitgrid.app/logs shows the device's live output over USB in the same browser. Useful for seeing whether it is joining Wi‑Fi, and worth having open if you contact support.

Firmware updates

Automatic updates

A new Gateway updates itself to the current firmware during setup, showing progress on your dashboard. After that it keeps itself current.

Updating by hand

Settings → Edge devices → your device → Firmware. You see the installed version, the newest available, and an Update button.

The update runs in stages — download, verify, install, restart — and the app shows which stage it is on. It takes a few minutes. The device keeps collecting until the final restart.

Rolling back

The Gateway keeps the previous firmware in a second slot, so Roll back returns to it. Only one version back is kept.

Home Assistant

Installing it

1. In HACS, add https://github.com/svitgrid/home-assistant-svitgrid as a custom repository of type Integration.
2. Install Svitgrid from HACS.
3. Restart Home Assistant.
4. Go to Settings → Devices & services → Add integration and choose Svitgrid.
5. Follow the prompts to link it to your Svitgrid account.

Keeping it updated

The integration checks for a new version every 12 hours and installs it. It never restarts in the middle of sending a command. You can switch this off under Configure → Settings.

If Svitgrid shows an "integration out of date" banner, your version is below the minimum we support — update it through HACS.

What it can do

• Read your inverter through the sensors you already have in Home Assistant, or by talking Modbus to it directly.
• Control your inverter: battery charge, work mode, solar sell, grid charge, generator force, generator port mode and export limit.
• Store data locally, in its own database, keeping about two weeks of detail and roughly two years of hourly history.
• Run your schedule locally, so events fire even with no internet.

Which inverters it works with

The integration ships ready-made mappings for dozens of models — Deye, Victron, Anenji/EASUN, Huawei, Solplanet, Solis and more, refreshed automatically from Svitgrid. If your model is not covered, you can map the entities yourself from the integration's options.

What it cannot do

• No Zigbee sockets or EV chargers. Those need a Svitgrid Gateway.
• No battery BMS reading. Home Assistant has no radio that Svitgrid drives; use a Gateway or your phone.

Local mode

Also called island mode. Two independent switches, and confusing them causes most of the surprises.

Why you would use it

• Your internet is unreliable, and you want the dashboard to keep working anyway.
• Your schedule must run during an outage that takes your router down with it.
• You would rather your energy data did not leave the house.

Turning it on

Settings → Home Assistant → Connection mode. Available on Plus and above.

What you lose with cloud sync off

When the box cannot be reached

If your phone is on local mode but cannot reach Home Assistant — you have left the house, or the box is down — Svitgrid falls back to the cloud automatically, provided cloud sync is on.

Smart devices

Settings → Smart devices.

What you can connect

• Smart sockets — Zigbee sockets, for a water heater, a pump, or anything you want switched on surplus solar.
• EV chargers — charge the car when the sun is out or the price is low.

Adding a socket

1. Open Settings → Smart devices.
2. Tap the add action in the top bar.
3. Put the socket into pairing mode — usually by holding its button until it flashes.
4. Svitgrid keeps a 2-minute pairing window open and shows the device when it joins.

What you can do with them

• Switch on and off by hand
• See what each one is consuming, and its history
• Include them in a calendar event — turn the heater on when the battery is above 80%, off when a blackout is scheduled
• Pick which ones an alert's "turn these off" suggestion actually switches

Mesh view

Zigbee devices relay for each other. The Mesh screen shows which are connected directly, which route through a repeater, and which are unreachable, with a Test connection button.

Battery monitors

Your inverter reports a single state of charge. A battery management system inside the pack knows far more: each cell's voltage, temperatures, how balanced they are, how many cycles the pack has done.

Supported monitors

How it is read

Adding one

Battery → Monitors → Scan. Svitgrid lists the battery monitors it can see, with signal strength. Choose yours and adopt it.

You can have up to 8 packs. Give each a name that says where it physically is.

What you get

Per-cell voltages, the spread between best and worst cell, temperatures, charge and discharge switch states, balancer activity, state of health, lifetime throughput and cycle count — plus a plain-language verdict at the top of the screen.

Pausing and diagnostics

Each monitor can be paused if you need the vendor app to have exclusive access. There is also a raw-frame toggle for support to diagnose an unrecognised monitor.

Moving collection to another phone

Useful when you replace your phone, or want an old one left at home as a dedicated collector.

How to do it

1. On the old phone: Settings → Inverter settings → Transfer collection. It shows a QR code.
2. On the new phone: sign in to the same account, open the household, and scan the code.
3. Collection moves across.

The code is short-lived. If it expires, generate a new one.

What changes

The new phone becomes responsible for reading the inverter. The old one keeps full access to the app — it simply stops collecting. Your history is untouched.

Your devices and signing keys

Settings → Your devices.

Because a command to your inverter is a real physical action, Svitgrid signs each one with a key held on the device that sent it. A phone with no key can view everything and change nothing.

Approving a new phone

When you sign in on a new device and first try to change something, Svitgrid asks you to approve that device. Confirm from a phone that is already trusted.

If your only approved phone is lost

Device detail

Each entry shows the device name, when it was approved, and when it was last used to send a command.

Revoking

Revoke removes a device's key. It can still view your data; it can no longer change anything. Do this immediately for a lost or sold phone.

Reset all signing

Revokes every key at once, including the one on the phone you are holding. Everything must be approved again from scratch. Use it if you think a key has been compromised.

Write history

Settings → Inverter settings → Write history.

Each entry shows the time, the setting, the value written, what triggered it — you, a calendar event, or the planner — and whether the inverter confirmed it.

When it is useful

• "Why did my battery drain overnight?" Find the event that changed a setting and see the value.
• "Did my schedule actually run?" A missing entry means it never fired.
• "Who changed this?" Every entry names the person or the automation.

Register dump

Settings → Inverter settings → Register dump.

Inverters expose their data as numbered "registers". This screen reads them directly, without Svitgrid's interpretation.

Two modes: read a specific range you are asked for, or scan a wider span to discover what a model exposes.

Profile and security

Settings → Account.

Edit your profile

Name, email address and photo. Changing your email requires confirming the new address.

Change your password

Under Security. You need your current password.

Two-factor authentication

Also under Security. Once on, signing in needs a code from your authenticator app as well as your password.

Delete your account

At the bottom of the Account screen, in the danger zone.

What happens to each of your homes depends on whether anyone else is in it:

• Homes where you are the only member are detached, exactly as described under Household settings — unreachable, anonymised, hardware access revoked.
• Homes shared with other people carry on without you. Ownership passes automatically to whoever has been a member the longest, and they keep the history, the equipment and the settings.

Households you were only invited to are unaffected — you are simply removed from them.

Household settings

Settings → Household settings. Owner or admin only.

What you can change

• Name and picture — how the home appears in your list.
• Location and country — drives the solar forecast, and decides whether Ukrainian tariff and blackout features appear at all.
• Blackout region and group — see Blackout schedule.
• Advance warning — off, or 1, 2, 3 or 6 hours before a scheduled outage. The default is 1 hour.
• Diagnostic code — a short code identifying this home. Quote it when you report a problem and support can find your system immediately.
• Battery reserve — the charge level Svitgrid will not plan below.
• Outage buffer — extra charge held back specifically to cover a scheduled blackout, up to 6 hours' worth.

Several homes

Settings → Households → Create household adds another. Each has its own inverters, tariff, members and history. Switch between them from the same menu.

How many you may own depends on your plan — see Plans and subscription.

Renaming and removing

Rename freely.

Deleting is different from what most people expect, so it is worth being precise. Svitgrid shows you a count of what will be detached before you confirm, and then:

• The home disappears from your account and from every member's account. Nobody can reach it again.
• Its name and identifying details are anonymised.
• Any Svitgrid Gateway attached to it has its access revoked, so it stops collecting. Where the app can, it also tells the device to wipe itself.
• The readings themselves are kept, detached and belonging to nobody.

Sharing with family

Settings → Members. Owner or admin only.

Inviting someone

Tap Invite, enter their email address, and choose their role.

Pending invitations are listed on your Members screen until accepted, and you can cancel one at any time. An invitation expires after 7 days — if it lapses, just send another.

Roles

There is exactly one owner, and the role cannot be changed or removed. To hand a home to somebody else, transfer ownership.

Changing or removing

Tap a person to change their role or remove them. An admin cannot remove another admin, and nobody can remove the owner.

Who pays

Invited members ride on the owner's plan. They are never asked to subscribe, and their access is whatever the owner's plan allows.

Electricity tariff

Settings → Electricity tariff. Ukrainian households only — the screen is hidden elsewhere, because these are Ukrainian tariff structures.

Choose your pricing model

Meter type

• Single zone — one price all day, 4.32 ₴/kWh.
• Two zone — day 4.32, night 2.16, night running 23:00–07:00.
• Three zone — peak 6.48 (08:00–10:00 and 20:00–21:00), semi-peak 4.32, night 1.73 (23:00–07:00).

Electric heating

If your home is registered for electric heating, switch it on. During the heating season, 1 October to 30 April, the first 2000 kWh each calendar month is charged at 2.64 ₴/kWh, and consumption above that at the standard rate.

Seeing the effect

Once set, the dashboard's grid card prices today's import and export, the battery card shows what charging from the grid cost, and the Finance tab in Reports shows the month.

Day-ahead market (РДН)

Where the prices come from

Svitgrid fetches the official day-ahead prices for Ukraine every hour and stores them by date and hour. Tomorrow's prices appear once the market publishes them, usually in the afternoon.

Seeing them

Turn on the price overlay on the Calendar timeline. Expensive hours and cheap hours become obvious at a glance.

Using them

With the Day-ahead market or Active consumer tariff selected, you can set:

• Minimum selling price — do not export below this, default 5.00 ₴/kWh.
• Maximum charging price — do not charge from the grid above this, default 3.00 ₴/kWh.
• Maximum battery cycles per day — stops arbitrage wearing the battery out, 0 to 4.

A Sell to grid or Charge battery calendar event can then take the price into account, and the daily planner will place windows in the cheapest and dearest hours by itself.

Plans and subscription

The plans

Organisation plans, for operators managing many sites, are quoted individually — email hello@svitgrid.app.

Prices are shown in US dollars; the store charges you in your own currency.

The free trial

Every plan starts with a 14-day free trial, handled by the App Store or Google Play. You are not charged until it ends, and cancelling before the end costs nothing. The trial is once per account.

If you own a Gateway

Managing your subscription

Settings → Subscription shows your plan and renewal date. Changing or cancelling is done in the App Store or Google Play, not in Svitgrid — Apple and Google own the billing relationship.

Restore purchases on that screen recovers a subscription after reinstalling or changing phone.

Current rollout status

Appearance and language

Settings → App settings.

Theme

Light, Dark, or System to follow your phone.

Language

Svitgrid is available in: English, Українська, Español, Português, Deutsch, Türkçe, Nederlands, Polski, Français, Italiano and العربية.

It follows your phone's language by default. Changing it here applies immediately and syncs to your account, so notifications arrive in the same language.

Data quality

The problem with collecting on a phone

A phone is not a server. It sleeps, it leaves the house, its battery runs down, the operating system closes background apps to save power. A phone collector typically covers 2 to 4 hours a day.

That does not merely lose those hours — it distorts what is built on them:

• Daily totals read low. Energy that flowed while nothing was watching is not counted.
• Charts have holes. Svitgrid draws a gap rather than inventing a line, so you can see it.
• The forecast learns from an incomplete picture and takes longer to become accurate.
• Scheduled events do not run. If nothing is at home at 02:00, nothing tells the inverter to charge.
• Alerts do not fire. "Inverter offline" cannot be detected by a collector that is itself offline.

Your options, best first

1. A Svitgrid Gateway. 999 ₴, collects 24/7, runs your schedule, reaches Zigbee devices and battery monitors. This is the option with no gaps.

2. Home Assistant. Free if you already run it, collects 24/7, can control the inverter and run schedules locally.

3. A dedicated phone left at home. Free if you have an old phone. Plug it in, join the home Wi‑Fi, open Svitgrid, allow the screen to stay awake, and disable battery optimisation for the app. Better than nothing, worse than either option above — phones still restart for updates and drop off Wi‑Fi.

4. Your everyday phone. Fine for trying Svitgrid out. Not a monitoring solution.

Checking your own data

Open Charts → Overview and look at the production heatmap. Collected hours and genuinely-zero hours are drawn differently, so gaps are visible as gaps.

The dashboard also has a Data collection health card on phone-collector households, which states plainly how much of the last day was actually covered.

Your data

What is stored

• Your account — email, name, optional photo.
• Your household — name, location, tariff, equipment description.
• Readings — power, energy, battery, voltages, temperatures from your inverter.
• Commands — every setting Svitgrid changed, and who triggered it.

Svitgrid does not collect the contents of your home network, and does not read anything on your phone beyond what the app itself stores.

How long it is kept

This is why a chart of last week has minute-level shape and a chart of two years ago has one point per day.

Where it is

On Google Cloud, in Europe. Traffic between your collector, the cloud and your phone is encrypted.

Local mode

With Home Assistant in local mode and cloud sync off, readings stay on your own hardware and never reach Svitgrid at all. See Local mode for what you give up.

Deleting it

Settings → Account → Delete account closes your account and detaches every household you own. The homes become unreachable to everyone, their identifying details are anonymised, and attached hardware loses its access. The stored readings are retained in anonymised form rather than erased row by row.

It cannot be undone, and nothing can be restored afterwards. If you want the readings themselves erased as well, email hello@svitgrid.app from your account address and say so.

Words explained

kW (kilowatt) — a rate, like the speed on a car's dial. How fast power is flowing right now.

kWh (kilowatt-hour) — an amount, like the distance travelled. 2 kW flowing for 3 hours is 6 kWh. Your bill is in kWh.

Inverter — the box that turns the panels' DC into the AC your house uses, and manages the battery.

Hybrid inverter — an inverter that handles solar, battery and grid together.

String — one chain of solar panels wired in series. Most homes have one or two.

kWp — the maximum power your panels could make in perfect conditions. Used to size the forecast.

Azimuth — which compass direction the panels face. South is 180°.

Tilt — the angle of the panels from flat. A typical pitched roof is around 30°.

SOC (state of charge) — how full the battery is, as a percentage.

Depth of discharge — how far down the battery is allowed to go before the inverter stops using it.

Export / feed-in — sending surplus power to the grid.

Import — taking power from the grid.

Curtailment — panels producing less than they could, because the battery is full and there is nowhere for the power to go.

Green tariff (зелений тариф) — a Ukrainian scheme paying households for exported solar.

Day-ahead market (РДН) — the Ukrainian hourly wholesale electricity market.

УЗЕ — the registration that lets a household buy at market prices.

Time-of-use (TOU) — the inverter's own built-in daily schedule of battery targets.

Work mode — the inverter's overall strategy: serve the house first, charge the battery first, or export.

Gen port — a second AC terminal for a generator or a switchable load.

Smart load — a load the inverter switches on when there is surplus power.

BMS (battery management system) — the electronics inside a battery pack that measure and protect each cell.

Collector / harvester — whatever reads your inverter and sends the data on: a phone, a Gateway, or Home Assistant.

Logger stick — the small Wi‑Fi module plugged into the inverter, through which most brands are read.

Modbus — the industrial protocol inverters speak.

Register — one numbered value inside the inverter, like a numbered pigeonhole.

Zigbee — the low-power radio used by smart sockets.

Island mode / local mode — running entirely on your home network with no internet.

MPPT — the part of the inverter that squeezes the most power out of a panel string. One MPPT usually means one string it can optimise independently.

CT clamp — a ring sensor clipped around your incoming mains cable so the inverter can measure what the whole house is drawing.

OTA — an update delivered "over the air", by Wi‑Fi, rather than by cable.

HACS — the community add-on store for Home Assistant, and how the Svitgrid integration is installed.

DHCP — how your router hands out addresses. It is why an inverter's address can change on its own.

AP isolation / guest network — a router setting that stops devices seeing each other. It will block your collector from reaching the inverter.

TOTP — the 6-digit code from an authenticator app, used for two-factor sign-in.

L1, L2, L3 — the three phases of a three-phase supply.

ФОП / legal entity — a registered business. Business entities do not qualify for the household green tariff.

Universal vs market supply — your contract type with your electricity supplier. The green tariff requires universal supply.

Commissioning year — the year your solar system was formally connected. It fixes which green tariff rate you are paid for its lifetime.

Troubleshooting

"Device is offline" or "no data since…"

If it is not paused:

1. Is the device powered? Check the status light — solid means data reached the cloud in the last 12 minutes.
2. Is your Wi‑Fi up? The Gateway needs the same network it was set up on. A changed Wi‑Fi password stops it silently.
3. Has the inverter's IP address changed? Routers reassign addresses. Reserve a fixed one.
4. Power-cycle the Gateway only after the above — it is rarely the answer.

Cannot connect to the inverter

1. Same network? The collector and inverter must be on the same Wi‑Fi. Guest networks are separate networks.
2. Correct IP address? Use Scan rather than typing it.
3. Correct logger serial? It is on the logger's label, not the inverter's nameplate.
4. Another app connected? Most loggers accept one connection at a time. Close the manufacturer's app.
5. Correct model? The wrong model connects successfully and returns nonsense.

The numbers are lower than my inverter's own screen

Almost always the generator port. If your inverter has a smart load or generator connected and you have not told Svitgrid, that power is subtracted from house consumption and displayed nowhere. See Smart load and generator port.

Charts have gaps

Your collector was not running. This is not a fault — see Data quality.

Everything reads zero

• Check the inverter is actually on.
• Check the correct model is selected — a wrong model can decode real data into zeros.
• At night, zero solar is correct.

The forecast is wrong

1. Check kWp, azimuth and tilt in Inverter settings → Solar configuration.
2. Give it two weeks to learn your roof.
3. Remember it forecasts potential. If your battery filled and the system curtailed, actual output is legitimately below forecast.

A scheduled event did not run

1. Was anything collecting at the time? No collector, no event.
2. Is your inverter controllable? Only Deye, Sunsynk and Sol-Ark can be controlled.
3. Is the planner still authorised? Authorisation expires.
4. Check Write history — it shows whether a command was sent and what the inverter said.

The Gateway keeps beeping

It plays a melody each time it applies a battery-charge command. There is currently no way to mute it; reduce how often your schedule changes that setting.

Smart socket keeps dropping off

Too far from the Gateway. Add a mains-powered Zigbee device in between to act as a relay, and check the Mesh screen.

The app is slow or crashes

Update to the latest version, restart the app, and if it persists, reinstall — your data is in the cloud and nothing is lost.

Still stuck

Email hello@svitgrid.app with your inverter model, what you see, and roughly when it started. A screenshot and a look at Write history will usually get you an answer in one reply.

Frequently asked questions

Is Svitgrid free?

No. Svitgrid is a paid app with a 14-day free trial, from $1 per month. There is one exception: if you bought a Svitgrid Gateway, you keep a live dashboard, manual control and safety alerts forever, even with no subscription. See Plans and subscription.

Note that plan limits are not currently being enforced — everything is unlocked while we finish the rollout.

Does Svitgrid work without internet?

Only with Home Assistant in local mode. Otherwise readings travel through the Svitgrid cloud, so both your collector and your phone need a connection.

Your inverter does not need Svitgrid. Its own time-of-use schedule keeps running regardless.

Can Svitgrid control my inverter?

Only on Deye, Sunsynk and Sol-Ark. Every other brand is read-only. See Supported inverters.

Can I use several inverters?

Yes. Add each one, and tell Svitgrid if they share a battery bank. How many depends on your plan.

Why do you need the logger serial number?

Most inverters are reached through a Wi‑Fi logger stick that acts as a gateway. The serial number is how a request is addressed to the right inverter behind it. Some brands do not need it — see Connecting to your inverter.

Can my family see my data?

Yes — invite them under Members. They ride on your plan and are never charged. Choose the Member role for view-only access.

What is the difference between kW and kWh?

kW is speed; kWh is distance. Your inverter making 3 kW for two hours has produced 6 kWh.

Why is grid power negative?

Negative means exporting — you are sending power to the grid rather than taking it. That is a good sign.

Why is my battery runtime shorter than I expect?

Svitgrid counts down to your inverter's own cut-off, not to 0%. A battery at 50% with a 30% reserve has 20% of usable charge left.

Will you support Growatt, SMA or Fronius?

They are not supported today, and no work is currently under way on them. Email hello@svitgrid.app with your model — demand is how we choose what to add next.

Why did my household disappear?

Almost always a different sign-in method. Signing up with Google and later signing in with email creates two separate accounts. Sign out and try the other method.

What is Fleet view?

A separate set of screens for operators who look after many sites at once — a map of stations, cross-site alerts, analytics and market arbitrage. It only appears if your account belongs to an organisation. If you look after your own home, you will never see it.

How do I report a problem?

Email hello@svitgrid.app with your model, the symptom, and when it started. Screenshots help.
