So, my scenario, large RV with a fairly large deep cycle battery bank. What I want to do is this. Kids want to watch tv at night and I don't want the genset running. The battery bank runs DC loads only of course so lights and controls. Now for the weird part... Hookup my inverter on my battery bank and plug the shore power cord to this inverter for tv power. This looks like an odd cycle that may or may not work and I don't know if this would damage anything? Definitely would have inefficiencies and losses but it's only for a few hours and I'll recharge at some point from the genset the next day. Any ideas on this? Thx guys. ?
