The XM1800 control panels even identifies when the inverter is in pass through mode (green light) or running off the batteries (yellow light). Not sure which inverter you are getting but the Xantrex (power on) will run on pass through until shore or generator power falls below 90 VAC and then switch over to battery power.
I'm not sure which inverter I will be getting, still looking and open to suggestions. Looking at the AIMS Power PICOGLF40W12V240VS 4000W 120/240V AC Pure Sine Split Phase Inverter Charger. seems to have good reviews and with the 240 volts it would duplicate the 240v 50 amp shore power? Not to sure on that, but it seems that the bigger the better.
Is there some advantage to having the 240 side of it? the one that only does 120 volts is cheaper, however I don't want cheap out on things like this but don't want to waste either!
