3 Phase and Single Phase 15 kW Generators

We stock both 15 kW 3 phase generator and 15 kW single phase generator models, so you can choose the configuration that matches your electrical setup. A 15 kW 3 phase diesel generator is typically specified for commercial and 3 phase generators industrial applications where heavier loads or motor-driven equipment call for a balanced three-phase supply. Each 15 kW 3 phase diesel genset in our range is built to cope with these demanding loads without compromising on reliability.

For smaller premises, domestic properties, or sites where single phase is the standard supply, a 15 kW single phase generator is often the more practical option. Every 15 kW single phase diesel genset we hold in stock is straightforward to install and maintain, and a 15 kW single phase diesel generator running at 230V produces roughly 65.2A, making it easy for an electrician to size cabling and protection accordingly. Our range includes both 3 phase diesel generators and single phase generators, giving you the flexibility to match power output to your existing infrastructure.
