Hi,
I have a grid-tied 15KW PV system powered by two SMA Sunny Boy 7.7KW inverters. It's a ground mount system, and the inverters are located inside a shed away from my home. I'm thinking of adding a LifePO4 battery backup system in my home with a Sunny Island inverter. I'm trying to understand how the AC coupling works. Would I be able to use my solar panels in the case of an outage if I have the Sunny Island?
I have a split 400A service with 200A going into the house (where I want to install the Sunny Island). The other 200A panel receives the output from my PV system. Not sure if the sunny boys are supposed to be electrically "downstream" from the Sunny Island to do what I described above.
Thanks in advance
