Just inherited an off grid system - has nice batteries that I would like to keep in good shape. Preparing for winter and possibility of many days with no sun so need generator. Problems seem to be that the inverter (aims 10k 48 volt) and the generator (generac 7.5k Power pac) are mismatched. Not enough power from the genny. Tried turning off house supply when charging and turned down the rate of charge to just under 10% still no joy - gen charges for 10 mins then inverter cuts it off.
So question is - how do I match or correct without breaking the bank. My thoughts are new dc generator (haven't found anything reasonable) new inverter.
Battery array is 2 strings of Trojan SPRE 06 415 giving me 20hour 740amp - House usage is 6 kwh per day max and i have 2 surge appliances (well pump and refrigerator)
Any thoughts on dc generator or sizing (and make) of inverter would be greatly appreciated.
