How to choose the right power size for your diesel generator set?

Oct 27,2026

Many buyers make the mistake of selecting generators simply by adding up the total load power. Load type, motor starting inrush current and site conditions all matter a lot.

*Resistive loads (lighting, heaters): Smooth startup, small safety margin required 
*Inductive motor loads (water pumps, air compressors): High starting inrush current, need larger capacity 
*Non-linear loads like UPS: Harmonics lead to overheating. Generator derating & 3-phase balance check required 
*High altitude, high temperature & dusty sites: Engine power derates, extra margin is necessary
