Hi:
I use our HDT to pull a racing trailer, and with the COVID shutdown, the batteries in the truck and trailer aren't very happy.
I am considering adding a couple of solar panels to keep the batteries topped off. In the truck, I've got the 4 starting batteries, and 4 golf cart batteries for the inverter (so 2 banks). In the trailer, I've got 2 critical batteries (one for the inside lights and generator starting, and 2nd to power the hydraulic car lift). I've got a 3rd battery in the trailer that powers a small inverter.
Do I need to keep the banks isolated from each other while charging? Is there a multi-bank charger that would do that? If there was such a beast, I was thinking of 2 panels and 2 chargers.
Thanks!
