Example sizing for a 12-hour outage: mini fridge 40 watts times 12 hours is 480 Wh, laptop 180 Wh, LED 50 Wh, phone 20 Wh, total 730 Wh. A 15 percent buffer makes 839.5 Wh. Divided by 0.90 depth of discharge and 0.90 inverter efficiency, the AC nameplate is about 1,036 Wh, which fits the about 1,000 Wh class (results 513 to 1,152). Compare that result to the station label. All 12 V DC devices would be about 933 Wh. The fridge 40 W is an average because the compressor cycles. — EXAMPLE. 480 + 180 + 50 + 20 = 730 Wh. 730 × 1.15 = 839.5. 839.5 / 0.90 / 0.90 = 1,036.42, shown as ~1,036 Wh. 12 V DC skips the inverter: 839.5 / 0.90 = 932.78, shown as ~933 Wh. Fridge 40 W is an average over the window.
