I am considering adding a split-phase Quattro to my house electric system to cover grid outages.
In most systems that supplement grid power with say a generator, a transfer switch selects between grid and generator, but only the hot legs are switched and all neutral connections remain interconnected. There is one neutral-safety ground connection at the service entrance.
I'd put a transfer switch on the output of the Quattros to route grid power to the loads in case of Quattro failure. To switch both hots and neutral would require a 3-pole transfer switch which is many times the cost of the typical 2-pole transfer switches available.
Would it be acceptable in this case to connect the Quattro in and out neutrals together? I'd also disable the internal ground relay since the service entrance neutral-safety ground connection would also be active at all times I can't think of a reason this would cause problems unless current sensing inside the Quattro was in the neutral path.
Sorry, I know this has been discussed before but not exactly in this situation.
