I do not want to own a generator due to storage space and risk of theft, but when my batteries get too low my AIO unit shuts down, and then I do not have the juice to turn it on to charge my batteries up via solar the next day when the sun comes out. Can I buy a basic (48V) charge controller and use a switch so that I charge the batteries via my panels. I do not need to power anything at this stage, I just want to charge them enough so I can then switch to the AIO unit. Assuming I can do this, what do I need to be careful of, and anyone have a charge controller they recommend for this? As you can guess I killed the batteries last night, so now I get to tear my trailer apart to get to them, undo the wiring so I can wire them up to parallel and charge them via my neighbors power (I do 4 at a time), which is less than ideal for an off grid system.
I have the Growatt 5000 ES, and 2 sets of 4-12V batteries wired in series/parallel, is that 4S2P?
Thanks!
