How much does a 500kVA generator cost in Nigeria?

The price depends on engine brand, whether it is open or soundproof, the control panel and whether you want a new or fairly used unit. Send your requirement on WhatsApp and we will get supplier quotes for your exact configuration.

How many kW is a 500kVA generator?

At a 0.8 power factor, a 500kVA generator produces about 400 kW of real power.

How much diesel does a 500kVA generator use?

Roughly 78 litres per hour at 75% load. Actual use varies by engine, load and condition.

Should I buy a soundproof 500kVA generator?

A soundproof canopy lowers noise and protects the set from weather, which matters on estates, hotels and offices. It costs more than an open set, so the right choice depends on where it will sit.
