My MPP 6548 with 3 EG4 LL 48v 100 amp system at my off-grid cabin has been working seamlessly for the past 2 years.
When I left two weeks ago the batteries were all three at 100% charge. When I arrived today the one closest to the bus bar and the inverter was 94% the next one was 15% and the furthest of the three was at 20% state of charge.
Any clue as to why that would happen in such a dramatic difference? I've never had this happen before. I currently have the generator charging all three batteries and will get them up to 100% and see how they do after that but just curious why that would have happened.
I do leave the system turned on while I'm gone to power the refrigerator and a single light but nothing else. The system does get turned off once winter hits.
TIA
