I use a battery -- 6kWh, 3600W inverter, with 6x 440W panels -- and don't feed power into the house wiring, but simply power the appliances in the same room as the equipment: Starlink, Mac Mini with 32" monitor, 16" i9-13900HX laptop, half a dozen small SBCs (5-15W each), fridge, espresso machine, air fryer, microwave, toaster, kettle, 4kW (output, 900W electricity) portable air conditioner, dehumidifier (250W). some LED lighting.

At the moment (spring) in half-decent weather all the above stuff is 100% off-grid. I'm still using grid power for hot water heating, dish washer, clothes washer -- all of which I do for free in my daily "Free Hour of Power" -- and for intermittent incidentals such as the water pump (e.g. runs for 15 seconds when I flush the toilet) and lighting in usually non-occupied rooms such as toilet, bathroom, and bedroom -- which together means I'm paying around 10c-20c per day over and above the fixed daily charge.
