Minimum Generator Size vs Total Running Watts

Fórmula

## 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.

Ejemplo Resuelto

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

  1. 01Running = 5,000W
  2. 02Surge = 2,000 x 3 - 2,000 = 4,000W extra
  3. 03Total = 5,000 + 4,000 = 9,000W = 9.0 kW
  4. 04Select a 10 kW generator.

Preguntas Frecuentes

What appliances have the highest starting surge?

Central AC units (3-5x), well pumps (3-5x), and sump pumps (2-3x) have the highest starting surges. Resistive loads like heaters and lights have no surge.

Should I size for the whole house?

A whole-house generator typically needs 15-25 kW. For a portable backup, prioritize essential circuits (fridge, sump pump, furnace, lights) and size accordingly.
