Question on inverter/charger AC backfeed
Hi all. New member here about to pickup a Grand Design this weekend and I'm already planning out upgrades to make the rig 100% usable off grid. I'm versed in electrical but the whole inverter/charger...

Can someone correct me if I'm wrong, but if you run one leg of the 50A service to the inverter and the second leg directly to the panel, when the inverter is running wouldn't you be backfeeding the second leg.
In theory, no ... BUT SHARING NEUTRAL BETWEEN 2 POWER SOURCES IS SOMETHING I WOULD NOT WANT TO DO !
Also, if you have any 240 loads, you are going to get "wild and crazy" voltages and frequencies !
The good news is that most modern inverter chargers include an automatic transfer switch and they will shutdown the inverter as soon as they see "shore power". Unless you do some unusual wiring, your scenario can not happen.

Inverter/chargers have installation manuals. It is common to have an inverter/charger with a 50a RV. Just do what the manual says and you will be fine.
