Understanding KVA

kVA (kilo Volt Ampere) is the total power capacity a generator can supply. To size correctly, add up your equipment load, allow for starting (surge) loads, and add a 20–25% safety margin.

Quick guide by use case

Use case Recommended KVA
Small shop / office 15–58.5 KVA
Construction site 125–750 KVA
Factory / plant 750–1250 KVA
Data center / hospital 1500–2250 KVA
