Engineering Calculator

Generator Capacity Calculator

Estimate the required generator size based on connected load, starting load, load type, and reserve margin.

Input Parameters

Total Running Load (kW)

Largest Motor Load (kW)

Optional. Determines starting surge demand.

Load Type

Simultaneous Load Factor (%)

Reserve Margin (%)

Power Factor

Recommended Generator Power

0kW

Minimum required continuous output power.

Recommended Apparent Power

0kVA

Standard rating used in generator datasheets.

Selection Note: Generator capacity must cover both the highest starting surge and the continuous running load with a safe reserve margin.
