    That is an option, but then the generator only powers half of the panel through the MP-II passthrough of L1, and other half of the panel would be provided by the inverter on L2 of the MP-II. I'm still leaning towards either 1) removing the ATS, feeding the MP-II only via shore power, installing...

    On a stand-alone basis the PD9160ALV is recommended by Battle Born for use with their batteries - it is a direct swap out of the stock WFO 55A unit that came in our 5th wheel. What I wasn't sure is if any considerations are needed when combined on the buss bar with the MP-II charging. From an...

    Thanks. If the generator is run through the MP-II, the MP-II will shut down one of the 120V legs from the generator since it would come in as two 120V legs in a single phase as opposed to 240 split phase. That unfortunately leaves only ~23A 120V of output on a generator that can output ~46A...

    Mine is the 5.5HGJAB-6755M; 120V / 45.8a / single phase

    Thanks - I started watching it earlier today... but hadn't gotten to the Generator section. Nice!!

    Holding out the question of the Multiplus... Typically on a 50A transfer switch, the two Onan 120v single phase outputs from the Onan QG 5500 HGJAB would have the Neutral bonded on the ATS with one hot on L1 and the other hot on L2. Basically the RV panel doesn't care that they are single phase...

    Looking for some help and or validation in ways to deploy the Multiplus-II in a 50A RV Toyhauler that has the Onan QG 5500 on board. Unfortunately, the Onan outputs two 120V legs in a single phase, which is no bueno with the Multiplus-II as it will see the single phase and drop L2 from the...

    The generator produces a single phase output of two 120V lines (not split phase). What others are reporting in various groups including Victron's user group is that if L1 & L2 come in on the same phase, then the MP-II will shut down L2 (MP-II thinks there is an issue) and puts L2 into inverter...
