Generator Sizing

Minimum kW = Running Watts + Starting Surge

Motors (AC units, pumps, refrigerators) draw 2 to 6 times their running watts during startup. Add the surplus starting watts of the largest motor to the total running watts of everything else.

计算示例

5,000W running load, largest motor is 2,000W with 3x starting surge.

  1. Running = 5,000W
  2. Surge = 2,000 x 3 - 2,000 = 4,000W extra
  3. Total = 5,000 + 4,000 = 9,000W = 9.0 kW
  4. Select a 10 kW generator.
