You said power a house not power the grid. I do HVAC and we need to winterize or work on houses with no power. Instead of dragging drop lights and cords everywhere I can use this to power up a circuit in the house with my inverter. I have used it in my own house during blackouts. I turn off the main breaker and power the circuit I need like the fridge, sump pump or heater. Don't use it if you do not have a basic understanding of electricity. Plug it into the house, then into the inverter, because the exposed prongs will be hot.
If you want to power the grid there is alot of info here, but they are not using solar.
