Multiple Inverters #239

Open neilrfuller opened 1 month ago

neilrfuller commented 1 month ago

Hi, I have a system with twin 3.6kW inverters each with 4kW of panels. Could you advise me if pv_opt can handle multiple inverters, or would I need 2 instances. Many thanks.

It's not currently set up to do that but it might be possible. What brand and model are the inverters?

Thanks for getting back to me. The inverters are 2 x Solis S5-EH1P3.6K-L. Tbh wish I had a single larger inverter for simplicity, but was told at the time a twin install offered benefits. I suspect it was just that larger inverters weren't in stock back then. I have the inverters communicating with HA via wills106/homeassistant-solax-modbus. Managed to install Solcast via BJReplay. Think I will get going using simple automations as suggested by GordonMarkus. My knowledge of HA very much at entry level!

I’d be interested to see if this works also - I have two 5kWh batteries and a single solis inverter, however can only push 3.6kw to the house at a time, so high power items (showers etc) would utilise more PV power if I had two on the go.

Cheers,

P

If free to choose again, I don't think I would go down the twin inverter route. I have a separate CT clamp for each inverter. I suspect that really an EPM (Export Power Monitor) should have been fitted to balance the inverters.
