Size guide
What size do you need?
Pick generator, battery storage or fuel tank, drag the slider (1 to 2000 kVA, or 100 to 70,000 litres for fuel tanks) and see the size band. Tell us your size and we'll source it. Bands are indicative only and your load is confirmed in your quote. kW is roughly kVA × 0.8 for running load only; motors and other equipment with high starting loads need extra headroom, and we’ll confirm sizing in your quote.
Use arrow keys to fine-tune, or type a size: kVA
30 kVA ≈ 24 kW running load at 0.8 pf
Compact site generator
Band: 11 to 30 kVA (indicative only)
