I have a proposal to put an 11.1 Kw solar array on my barn and wire it into the house. We (meaning my wife) will NOT stand for any more trenching or digging up our landscaping so we are somewhat constrained.
Here is a schematic of the proposed wiring system. My house is two houses in one, with separate wiring and plumbing for each house. Critical circuits in the west end are supported by a generator. The east end has no critical circuits. The electrical panels are fed by a common meter, so they aren't totally separate. The plan is to wire the solar array into the east end panel as shown in the diagram. My question is what happens if the power goes out. The system will still be fed by the 11.1 Kw array, that won't be enough to power the whole house if everything is running, but it might be enough to keep the transfer switch from engaging the generator. So - is there typically some kind of under voltage switch on the solar inverter that will disconnect the solar array if it is overloaded and let the generator do its thing, or what?
