Guys,
Which inverters (or PV inverter manufacturers) are most supported by Homa Assistant intergrations?
Is it perhaps Fronius, FoxESS, Huawei, Solar Edge, Sofar Solar, Growatt, GoodWe, SMA, Solis?
Reading values from Fronius inverters works pretty good. If you need advanced data or want to write something, you’d need to use Modbus instead of the core Fronius integration.
SolarEdge work well with a custom component.
I use a USB RS485 adapter plugged in to my server which runs HA in Docker.
I took this script and tweaked it to work with my Solis inverter:
The Solis Wifi dongle and the RS485 USB adapter share access to the inverter. This may not be the “right” way to do it, but it seems to work fine.
The official dongle only polls for values every 5 minutes and because…well, who knows…I decided that wasn’t often enough, hence using the adapter.
What about SMA inverters?
Are there any integrations for this manufacturer?
I developed a SolarEdge modbus custom integration and use it for my own system at home.
It’s available in HACS too.
