Wading Trough ? To Excellence
I bulked up my old lead acid 48V battery bank up with a generator to a full charge. My new LiFePO4 48V replacement charges up to 54V (top charging voltage as per mfg. spec.) and quits drawing current from the generator into the batteries. I don’t understand why. Consequently I am unable to fully charge the battery bank. Does anyone have any ideas why this happens? The battery bank is getting more depleted by the hour. Recharging only seems to bring up battery voltage, not Ah.
Generator is a 120/240V capable of both voltage and 120A. MS-4000 Magnum Energy inverter/charger is limited to 60A charge current. Battery manufacture has spec. out the following: System Voltage 48V, Max charging voltage 54V, LBCO@42V, operating voltage 48V. Battery Ah rating is 200Ah. Each battery consists of 16 individual cells. I have 2 batteries in parallel on 2 charge controllers and 2 arrays.
