Hey all,
We are designing our off grid setup on our 5th wheel and have arrived at a puzzle we are struggling to solve. We have settled on a Victron Quattro 24/5000/120-100 120V for the center of the system. Our rig is a 50amp wiring setup, but we wanted the 24 volt and higher output of the Quattro as opposed to the Multiplus II which would accept the input of the split phase but is a 12 volt 3000 watt system. So now we are trying to solve the wiring of the 240 volt split phase into the Quattro. Ideally we would like to convert the split 240 into single phase 120 and feed it all into the Quattro and convert the rigs sub panel to single phase. This simplifies the wiring and load balancing concerns. We have been looking at Victron's Autotransformer but it is not clear if it does what we are considering. It looks more like it's designed to simply balance loads across the two lines, not combine/convert the input to single phase output.
We would like to avoid running one of the legs into the sub panel and the other leg to the inverter. Doing it that way requires some loads be unavailable when running on shore power and cuts the available current in half.
Running L2 into the AC/2 input of the Quattro is an option (maybe: the neutral is a puzzle here) but it is unclear if the Quattro will tap AC/2 when both are live. The wiring diagrams and literature lead me to believe it will switch between AC/1 and AC/2 but will not feed from both simultaneously. In fact I am unsure what happens if both are live. (On a side note: if a generator was wired into AC/2 in and both the generator and shore power where live, for example a 15amp mooch docking shore power feed supplemented by a generator, would it combine 1 and 2 for the hybrid feature or will it ONLY draw from the battery bank for the hybrid function?) If this is a misunderstanding that would make me very happy, but I doubt it, that would make the quattro essentially the same as the Multiplus II.
I have a very good understanding of DC current, and a reasonable grasp of AC current. When you start talking about the intricacies of split phase/single phase I begin to flounder. Any assistance and advise would be welcome.
Thank you in advance,

Edit: Updated the post with the more specific model of Quattro that we have.
