I have been running my [
MultiPlus-II 2x120V for a few years but recently added 6000w of solar to my rv and a eg4 6000xp to convert it. the 6000 feeds the MultiPlus-II 2x120V through a 50 amp plug when boondocking and the 6000 is out of the system completly when pluged into shore power. the problem comes when the sun goes down. if running both ac’s i need about 2400 watts and the solar does this till preetty dark but the 2x120 ignors power limits on leg 2.
Here is the scenario that kills me. 2 ac’s running and a limit set to 9.3 amps (lowest the Victron will go. it pulls 1100 watts from leg 1 and another 2400 from leg 2, running my ac’s and bulk charging the 12v system…why does it use unlimited power from leg 2? This seems dangerous with a dogbone on a 15-amp service. I have enough solar to run both ACs, but not if the charger is running full out. 12V system is always above 95% as it’s 1100Ah and only runs 12V loads.
Is this becuase the 6000xp is a true 240 center tap? does it see a dogbone as 2 in phase connections so it knows its only one? still seems off that if I plugged in 240v 50 amp shore power and said only pull 9.3 amps, it would melt the system down if leg 2 wanted 50 amps one wires that are not rated for it. .
