Hi Chris, I suspect that the charger in the Apollo Inverter/Charger is undersized, especially since all of the loads are -48V. Conversely, the array is very oversized and the controllers float most of the time. The charge controllers were working fine last I checked. It's difficult to access the site right now, it includes a 30 mile snow mobile ride. We intended to put a comprehensive remote monitoring system but it didn't get put in before the snow came. I want to get up there and help the system limp along until snow melt when we can do a thorough assessment. The generator guy went up there and someone had pulled the stop switch on the genset. The battery voltage was around 5V on a 48V bank. Yikes!
Thanks for the contact info.
