We recently purchased a small mountain home that is off-grid. Our solar system is pretty small supporting just one battery bank (8 batteries.) We had a few overcast days and needed to run our generator - we ran it until the inverter showed float, but both Watts and KWh showed 0. We still had power, though. Seemed odd to us, wasn’t sure if that indicated a problem? Any ideas? Also if it matters it was VERY cold that particular night - around 0*F.
