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. ref# power description 1 split phase 12KV 2 split phase 480V 3 3a split phase 240V split phase 240V wire size specifications use existing 6 move from dog building 1 1 ?? sunny boy switch web sites 4 5 6 7 split phase 240V split phase 240V split phase 240V split phase 240V 400 400 125 125 1 1 1 1 approx 14x18" box, 8" deep approx 14x18" box, 8" deep capstone C-30 capstone C-30 8 8a 9 10 11 split phase 240V split phase 240V split phase 240V split phase 240V 400 30 30 60 1 ? ? ? approx 14x18" box, 8" deep sunny boy sunny boy ? 12a split phase 240V 400 1 use existing shop switch 12b split phase 240V 400 1 use existing gen room switch Outback can gang up to 8 inverters in parallel and manage batteries and solar panels.

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.
