3000W pure sinewave inverter. WOW! Very nice. I have a 2000W pure sinewave inverter charger.
I dumped the junky converter charger but left the transfer switch. Guess I could have taken that out too.
Anyway I through wired from the transfer switch to the inverter charger to the 110 panel. My battery bank is only a single 4D AGM so that is only 215AH.
The procedure for setting up for dry camping is to turn the 110VAC circuit breakers OFF for the fridge & waterheater & operate the inverter manually as needed via the remote control panel.
