Losing battery bank power. We have been off grid for 6yrs, last year we added 12 panels to our less than 3 kw system. We are near or at 5 kw now. We have 24, 2v gel batteries which gives us 48v system. Outback 80 charge controller and xantrex inverter. We also upgraded our generator to a 5 kw genie. In their last 4 month we have been walking up to 47.2 VDC, Usually its 48.4 VDC or higher. Does anyone have any ideas
