We've got a ground mount 13.7kWp grid tied system, with SolarEdge SE11400H - US inverter, no batteries. If the grid goes down, as a community service, we would like to be able to charge as many "large" batteries during the day as possible. By large I mean RV or heavy equipment types of batteries or the occasional car battery for a family with a small inverter to get through the night. Right now we average about 90kWh/day production. 300+ days of sun. We have a sufficient solar generator to get us through night-to-night so "lighting the house" is not the goal.
The array has a quick disconnect along with the inverter and it's about 130' to the house load center & meter and additional disconnect, if that matters.
We don't want to make the investment in batteries for the house alone for the unlikely need and would like as flexible system as possible if the need arises. We are looking for recommendations on charge controller and how "easy" it would be to accomplish our goals with our existing setup.
Curious about your thoughts.
