I have four 48VDC, 5KVA Multiplus II's in USA 60Hz, Can I install 2 MP's in parallel on each phase on the input of a 100 amp passthrough Autotransformer and then expect the Autotransformer to pass all the MP's current and also be able to then push 28 amps from one phase to the other when needed? Maybe a dumb question, I just don't understand the Autotransformer very well yet.
