Diesel Generator Buying Guide

A working guide for importers, distributors and project buyers: how to size the set, choose the enclosure and engine, check the supplier before you pay, and agree terms that protect your money. 125 kVA to 3000 kVA, built in our own plant in Hunan, China.

Start Here: Four Steps to Specify Your Set

1 Work out the load, not the price

Add up the running kW, then allow for starting current on motor loads and pick a prime or standby rating with headroom. Getting this wrong is the most expensive mistake in the whole project — it either overloads the set or buys you capacity you never use.

2 Choose the type and enclosure

Open frame for indoor plant rooms and budget projects. Sound-attenuated canopy where noise matters — hospitals, hotels, residential. Containerised where you need weather protection, offshore transport or easy expansion. Trailer-mounted when the set has to move between sites.

3 Pick the engine

Cummins, Perkins, Yuchai and Shangchai cover the range we build. Yuchai and Shangchai deliver the best value in the 125–2000 kVA band and have parts networks across Africa, the Middle East and Southeast Asia. Cummins and Perkins suit tenders and projects where the brand is written into the specification.

4 Verify the supplier before you pay

Every generator looks the same in a catalogue photo. What separates a factory from a trading desk is what you can inspect: the production line, the load bank, the test reports, the certificates, and whether the name on the invoice matches the name on the certificate.
