The VOC for a 48 VBB is to low for most batteries. IF there is a combiner box and there is a even # of OCD then I have rewired the DC input ( remove the + from 1 OCD and connect it to module #2’s negative wire) to increase the DC input. OR there are a # of higher voltages of charge controllers that make it easy to reconfigure array input voltages to the CC. Batteries IF there are 8, 16 six volt batteries then sure. > On May 17, 2021, at 10:31 AM, Maverick Brown <[email protected]> > wrote: > > Now is a good chance to see if switching to 48V is feasible.
