Can you use 2 - 24v chargers on a 48v bank?
Recently made the swap from 24 to 48 volt system. As yet I do not have a 48v charger, but do have 2 - 24v chargers. Numerous cloudy days and the impending/now up us ice storm has forced me to charge the battery bank with other than solar. After shutting everything down, I disconnected the wire between batteries 4 and 5 making 2 banks of 24v and hooked up a charger to each bank.
The question is, could I have left all 8 in series with the system up and running as normal and just connected a charger at each 24v part of the 48v series string (Charger #1 with positive at battery 1 and negative at battery 4 and Charger #2 with positive at battery 6 and negative at battery 8)? Battery 1 positive and battery 8 negative are the 48v leads to system.
4-Risen 320 watt in series/parallel, 8-215ah 6 volt GC2 batteries in series, Exeltech 1100 watt/48 volt inverter, Tristar 45 MPPT controller.
