Good evening.
I am searching for informations about a PV inverter with good compatibility to HA.
It is just a little Photovoltaic system with 12 x 425 watt each module. 5100 W in Sum. (Small, because it is only a garage roof).
Aims in HA:
- Presentation and evaluation
- Influencing / using intelligent control with regard to excess charging in a small battery (5 kWh BYD?)
- Influencing / using intelligent control with regard to my existing Wallbox Keba P30 C
I am not yet clear whether I should outsource this intelligence to HA or purely via inverters.
I would also find it extremely interesting to activate SMALL consumers in the house if there is an excess of electricity. e.g. fan heater, dehumidifier etc. This could be by means of Shellys, but I’m still looking for integration with this function. The crowning glory would be a dynamic proportional adaptation of e.g. a fan heater or IR spotlight to PV power (similar to wallbox).
I am currently aware of Fronius and Growatt. Although Fronius must have a high level of compatibility and protocols, it probably cannot provide a real emergency power supply. (Would not be a must have for me, Likewise, the battery is just a mind game)
Important: This is just the garage. As soon as the financial means are available, I will also install about 20 kWp on the roof of the house. But I don’t like to wait that long. Because it is fun😊
Thx a lot, good night. Franz
