Setting both switches to on2 will completely bypass inverter bank. 3-position manual knife switch (on1, off, on2), normally set in on1 position, which passes power from inverter bank to distribution panel. Setting both switches to on2 will completely bypass inverter bank.

General questions: DG room. This room will be partially insulated by construction of sheds on the west and north side of the building. Should we insulate the south and east walls by adding a layer of insulation and panelling? (roof is already wellinsulated). Garage door may need some special work to insulate. What is a good ambient temperature for the DG room? How do the solar rooftop electrical connections work? How will we conduit wires into the DG room. Where will the grid-tie inverters go? In the DG room? How about the wind turbine? What kind of interface will the control system have? Will it have an IP address and serve http? A serial interface to a host computer? I assume the controls box will be in the DG room, but it would be good to operate it remotely. I have fairly detailed pencil drawings now of the generator room - but have not converted to dwg format. Too big to scan. I can take a photo if that would be helpful. There are 2' square openings in the east and west walls of the DG room, way up high (12' above ground). And some ducting for exhaust-ventilating the radiator of the diesel generator. Could we use that ducting to install a radiator for shedding excess heat from the MTG's when the TES tank is unavailable.
