Multiply kilowatts (kW) by hours to get kilowatt hours (kWh).
Power demand by appliance:6.7 kW - Level 2 EV charger
6.0 kW - Clothes dryer
2.6-3.1 kW - Central air conditioner (more on that below)
2.3 kW - Microwave oven
1.8 kW - Dishwasher (startup only, drops to 0.1 kW during wash)
1.0 kW - Level 1 EV charger
0.8 kW - Toaster
0.7 kW - Freezer compressor for refrigerator (Energy Star). Intermittent.
0.6 kW - Clothes washer on spin cycle
0.2 kW - Lights in the evening (LEDs of course)
0.2 kW - TV
0-2.0 kW - demand water heater. Power draw depends on temperature of the water in the solar water heater tank. Zero if the water’s already hot.
We have a 1953 Chambers stove that runs on propane.
Our batteriesThe two Powerwall batteries together provide about 27 kWh of use capacity.
Even with intermittent light clouds, our solar system generated 27.2 kWh (see below).
The two Powerwalls together can provide 10 kW continuous output, or 14 kW peak. That's enough that we don't really have to worry about what the family turns on, provided we get some sunshine to recharge the batteries. One of those 3-day gloomy periods might put the kibosh on heavy use of the clothes dryer.
