We had an outage on Tuesday: Shygar 7.500kW | Live Output When looking at it, it seems like even though the sun was out, there wasn't enough solar coming in to charge the battery. But the battery was still at a pretty high level. Does anyone know how this is supposed to behave? Does it not charge until a certain battery percentage or something like that? Just wondering what expected behavior of charging while using only battery power is supposed to work.
