Hi Dave I don’t know if you paralleled A battery with the output if you’d damage the LCB. You won’t hurt the pump. A diode on the output of the LCB side would take care of that though.
Might be worth a test? Of course if you’re going to be putting in a battery then maybe just use a CC/PV instead of the LCB. Either method will probably need some kind of shutoff unless youve got lots of water. Jay > On Aug 2, 2020, at 4:47 PM, Dave Angelini Offgrid Solar > <offgridso...@sti.net> wrote: > > > Thanks Jay !
