Connecting to your inverter
Most brands need two things: the inverter's address on your home network, and the serial number of the Wi-Fi stick plugged into it.
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.
Which brands need what
| IP address | Logger serial | |
|---|---|---|
| Deye, Sunsynk, Sol-Ark, Solis, Sofar, SRNE, Megarevo, KSTAR, Afore, TSUN, Swatten, CHINT, INVT | Yes | Yes |
| Victron, Huawei, Solplanet, LuxPower/EG4 | Yes | No |
| Anenji | No | No — it dials out to us |
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.
Give the inverter a fixed address
Routers hand out addresses on a lease and can change them. In your router settings, reserve the current address for the logger's MAC address. Otherwise the connection breaks every few weeks for no visible reason.
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.
