I am looking at purchasing four multiplus II 48/3000/35-50 120v to put in a 2+2 configuration -- 2 parallel unites on each phase of a 240v split phase. I'm primarily going this route over a larger 230v Quattro + autotransformer due to the significantly lower zero load draw (52w for 4x mutiplus II vs 110w for a 15kva Quattro).
With low power consumption in mind, I can't find a clear answer to whether or not parallel / split phase muliplus II units can be configured to go into search mode under zero load conditions. This would bring my standby power draw down to 12w which would be excellent.
I know the manuals state AES mode does not work in a non-standalone configuration, but what about Search mode?
