[RE-wrenches] RV solar with SunPower

[Dave Angelini Offgrid Solar]

I believe all of the E series will work. It was a series before that had
issues when not used as designed for. This unit is for a module inverter
and you would have to isolate the PV wiring or remove the inverter.

It is a great module and worth doing. You will need an mppt for 55 MPV
which almost any can do.

Good Luck!
