Thought I would update this thread...........
I have the Autotransformer in my possession and plan to do the install next week. It looks pretty straightforward; I will intercept the input from the generator prior to reaching the transfer switch. The way it will be wired, the (2)v120V lines from the generator (sams phase) will feed into the Autotransformer on L1 which will then provide (2) lines out (L1, L2) which will now be 180* out of phase just like the 50A shore power input.....only difference will be that each line will only have 3600W (30A) each vs. the 6000W (50A) with a shore power connection.
Why is this important
Because right now when I run the generator L1 (1/2 the panel) is fed via pass-through and L2 (other 1/2) is fed by the 2nd inverter from the batteries while the 1st inverter is charging the batteries.......this of course is not the case with a 50A shore power connection because both L1 and L2 are 180* out of phase and each line passes straight through as well as BOTH are charging the batteries with a total output of 280A (@12V) which gets the batteries charged twice as fast
I will have to do a little power management if I need to run the generator AND run both AC units at the same time which can cause the breaker at the genny to trip, but in our system, we can set the available amps to 30 or any number actually, and the Inverter/chargers will manage the loads based on that without putting excess draw on the genny
Is that as clear as mud
