How it works

Svitgrid connects to your solar inverter through its data logger (Wi-Fi stick). The data logger communicates using the Solarman V5 protocol (or Modbus TCP for Victron). The app reads register values from the inverter to display real-time metrics.

There are two connection modes:

1. Direct mode - Your phone connects directly to the inverter over your local network
2. Edge device mode - A Raspberry Pi gateway collects data 24/7 and sends it to the cloud, so you can monitor from anywhere

Dashboard Overview

Understanding your solar dashboard.

The dashboard is your home screen. It shows a real-time snapshot of your solar system with four key metrics:

Live power flow with energy sources chart and grid voltage monitoring

Energy Summary

Below the live metrics, the energy summary shows daily totals:

• Daily Production - Total solar energy generated today (kWh)
• Daily Import - Energy bought from the grid today (kWh)
• Daily Export - Energy sold/fed to the grid today (kWh)
• Daily Load - Total home consumption today (kWh)

Auto-refresh

In Direct mode, the dashboard refreshes every 5 seconds while the app is open. In Edge Device mode, data arrives as new readings are collected (typically every 5-60 seconds depending on configuration).

Fullscreen Mode

Tap the expand icon to view the dashboard in fullscreen landscape mode - useful for wall-mounted tablets or presentations.

Power Flow

Visualize how energy flows through your system.

The Power Flow card shows an animated diagram of energy movement between four nodes:

Nodes

• Solar (top) - Your PV panels. Shows current combined output from all strings.
• Battery (left) - Your battery bank. Arrow direction shows charging (in) or discharging (out).
• Grid (right) - The utility grid. Arrow direction shows importing (in) or exporting (out).
• Home (bottom) - Your home load. Always receiving power from one or more sources.

Reading the flow

Animated dots flow between nodes to show where energy is going. The thickness of the flow line indicates the relative power level. Common scenarios:

• Sunny day, low usage: Solar feeds home + charges battery + exports to grid
• Sunny day, high usage: Solar feeds home, battery supplements
• Night time: Battery and/or grid feeds home
• Grid outage: Battery feeds home (if battery has charge)

Energy Charts

Visualize your energy data over time.

Chart Types

Stream Graph

Shows stacked energy sources over the course of a day. Each color band represents a source (solar, battery, grid). The width of each band shows the relative contribution at any moment.

Production Chart

A line/area chart showing solar production power (kW) over time. The curve typically follows a bell shape peaking around solar noon.

Consumption Chart

Shows home load power over time. Spikes indicate high-consumption appliances turning on (ovens, EV chargers, air conditioning).

Grid Chart

Shows grid import (positive) and export (negative) over time. Ideally, you want more export than import.

Time Ranges

Swipe between charts in the carousel, or tap the time range selector to switch between:

• Today - Hourly data points
• Week - Daily totals
• Month - Daily totals

Calendar View

The Calendar tab shows hourly energy breakdown for any selected day. Each bar shows the energy mix (solar, battery, grid, export) per hour, making it easy to spot patterns.

Hourly energy breakdown by source for the selected day

Battery Status

Understanding your battery metrics.

State of Charge (SOC)

Shown as a percentage (0-100%). This is the main indicator of how much energy is stored in your battery.

Battery Power

Shows how fast the battery is charging or discharging:

• Positive value = Charging (energy going into battery)
• Negative value = Discharging (energy coming out of battery)
• Zero = Idle (battery is full or inverter decided not to use it)

Battery Voltage

The current voltage of your battery bank. This varies by battery chemistry and configuration. Typical ranges:

• 48V systems: 44-58V (LiFePO4), 44-56V (lead-acid)
• High-voltage systems: varies by manufacturer

Battery Override

Create custom battery charge/discharge schedules to override the inverter's default behavior. Set time windows, repeat patterns, charge sources, and target battery levels.

Create a battery charge override with time, source, and target level

Households

Managing multiple properties and sharing access.

What is a Household?

A household represents one physical location with a solar system. Each household has its own inverter configuration, dashboard, and energy data.

Multiple Households

You can add multiple households to your account. Switch between them using the dropdown at the top of the dashboard. This is useful if you have solar on your home, vacation house, or office.

Adding a New Household

Go to Settings > Households > Add Household and follow the onboarding wizard for the new property.

Inviting Members

Share access to a household with family members or colleagues:

1. Go to Settings > Household Settings
2. Tap "Invite Member"
3. Enter their email address
4. They'll receive an invitation link to join the household

Roles

Solar Forecast

Predict your solar production.

How it works

Svitgrid calculates expected solar production based on:

• Your panel location (latitude, longitude, altitude)
• Panel configuration (tilt angle, azimuth direction)
• Panel capacity (kWp)
• Weather forecast (cloud cover, temperature)
• Sun position algorithm (sunrise, sunset, solar noon)

Configuring Solar Strings

For accurate forecasts, configure your solar string(s) in Forecast > Configure:

• Capacity (kWp) - Total rated power of panels on this string
• Tilt - Angle of panels from horizontal (0 = flat, 90 = vertical)
• Azimuth - Compass direction panels face (180 = due south in Northern Hemisphere)

Forecast vs Actual

The forecast screen shows predicted production (shaded area) overlaid with actual production (line). This helps you identify underperformance caused by shading, dirt, or equipment issues.

Battery Forecast

Based on your solar forecast and typical consumption patterns, Svitgrid also predicts your battery charge level throughout the day.

Troubleshooting

Common issues and how to fix them.

Can't connect to inverter

Check network connectivity

• Ensure your phone is on the same Wi-Fi network as the data logger
• Try pinging the inverter IP from another device
• Restart the data logger (unplug the Wi-Fi stick and plug it back in)
• Check if your router has AP isolation enabled (it blocks device-to-device communication)

Check connection settings

• Verify the IP address hasn't changed (routers may reassign IPs)
• Confirm the port is correct (8899 for Solarman, 502 for Victron)
• Double-check the logger serial number

Data shows 0 or no values

• PV Power is 0 - Normal at night or if panels are in complete shade
• All values are 0 - Connection issue or wrong inverter model selected
• Some values show 65535 - Usually means the register doesn't exist for your model. Contact support.

Edge device not found during scan

• Ensure Bluetooth is enabled on your phone
• Ensure Location permission is granted (required for BLE on Android)
• The edge device must be in pairing mode (slow blinking LED)
• Stay within 5 meters of the device during scanning

Edge device is offline

• Check that the Raspberry Pi has power (LED should be lit)
• Verify your Wi-Fi network is working
• If you changed your Wi-Fi password, you'll need to reconfigure the device
• Try restarting the Raspberry Pi by unplugging and reconnecting power

Forecast is inaccurate

• Verify your panel tilt and azimuth are correct
• Ensure the location pin is at the right position on the map
• Check that capacity (kWp) matches your actual panel ratings
• Partial shading from trees/buildings reduces actual production below forecast

App is slow or crashes

• Update to the latest version from the App Store / Google Play
• Clear app cache (Settings > Apps > Svitgrid > Clear Cache)
• Restart the app
• If the issue persists, contact hello@svitgrid.app with your device model and OS version

Frequently Asked Questions

Quick answers to common questions.

Is Svitgrid free?

Yes! Svitgrid is completely free to download and use. There are no subscriptions, premium tiers, or hidden fees.

Does Svitgrid work without internet?

In Direct mode, yes - the app communicates with your inverter over your local network. You don't need internet for live monitoring. Historical data and cloud features require internet.

Does Svitgrid store my data?

If you use the Edge Device, readings are stored securely in the cloud (Google Cloud / Firebase). You can export or delete your data at any time.

Can I use Svitgrid with multiple inverters?

Currently, each household supports one inverter. If you have multiple inverters at the same location, create separate households for each.

Why do I need a data logger serial number?

The Solarman V5 protocol requires the logger serial to authenticate communication. Without it, the data logger won't respond to queries. Victron systems don't require this.

Can family members see my data?

Only if you invite them to your household. Each member needs their own Svitgrid account, and you control who has access.

What's the difference between kW and kWh?

kW (kilowatt) is a rate - how much power is flowing right now. Think of it as the speed of your car. kWh (kilowatt-hour) is a total - how much energy was used over time. Think of it as the distance traveled. If your panels produce 4 kW for 2 hours, that's 8 kWh of energy.

Why is my grid export negative?

In Svitgrid, positive grid values mean import (buying power) and negative means export (selling power). This follows the inverter's convention of measuring grid power from the home's perspective.

Will Svitgrid support Growatt / SMA / Fronius?

We're actively working on adding more brands. Join our Telegram group (@svitgrid) to stay updated on new inverter support.

How do I report a bug?

Email hello@svitgrid.app with a description of the issue, your device model, OS version, and screenshots if possible. You can also report issues in our Telegram group.
