I am designing the electrical setup for a full time custom RV. It has a 48v battery bank, solar panels, and will see 110v shore power (15amp-30amp plus 50amp split phase). There will be no propane appliances so having 220v available for AC, water heating, and stove would be ideal. It would also be nice to be able to make use of both legs of a 50 amp split phase hook up in a balanced and simple way. I have 2 paralleled honda 2000w generators mounted on a vehicle that will be just plugged in to the shore power when used.
The best solution I have been able to figure out (excluding dual Quattros because that's out of my price range) is to use the less expensive 220v Multiplus 48v/5000 with Autotransformers on both ends. This allows me to use the 220v from a split phase input or step up any 110v input, then step down the passthrough and inverter output to 110v as needed.
Any thoughts about this setup? Will I have excessive losses due to the two transformers?
Otherwise I would just get the Quatro48v/5000/110v and have to live without 220v or making use of both legs of split phase 50amp shore power. Side question, could I connect the two legs of the split phase to the two Quattro inputs and use them both? Im thinking probably not..
Thanks
