Substantial Power in the 800 kVA Range

For operations that need serious, sustained power supply, an 800 kVA generator offers the kind of large-scale capacity required by major manufacturing sites, distribution centres, and other high-demand facilities. As an 800 kVA diesel generator, each unit is built to handle prime or standby duty with ease, providing the reliable power generation needed to keep critical operations running without interruption.

Whether you refer to it as an 800 kVA genset or generator, you can expect the same heavy duty construction, efficient fuel consumption, and dependable performance under sustained load. Every 800 kVA diesel genset in our range is fully tested before dispatch, and as a leading stockist we hold a wide selection of generators in our own inventory, meaning faster access to ex-stock units than waiting on a lengthy factory build.

Open Configuration for Flexible Installation

At this scale, many generators are installed within a dedicated plant room, purpose-built enclosure, or existing generator house rather than sitting exposed outdoors, which makes an open configuration a practical choice. An 800 kVA open generator is supplied without an acoustic canopy, giving engineers straightforward access to the engine, alternator, and control panel for routine maintenance and servicing. An 800 kVA open diesel generator like this suits sites where the unit will be housed indoors or within a bespoke enclosure, allowing the building itself to handle noise and weather protection.

If your site is noise-sensitive or the generator needs to sit outdoors without additional housing, our silent generators range may be a better starting point, offering the same power output within a weatherproof, acoustic canopy.

Reliable Three Phase Power for Large Sites

An 800 kVA 3 phase generator is designed to handle the demanding electrical loads found in large commercial and industrial environments, from heavy machinery and process equipment to substantial HVAC and lighting systems. An 800 kVA 3 phase diesel generator of this size is often specified for manufacturing plants, large construction sites, and facilities that need dependable standby power to protect against costly downtime during a mains failure.

If you need an 800 kVA 3 phase genset for a temporary project or a permanent installation, our stock is ready for fast dispatch across the UK and efficient export to international markets. Every 800 kVA 3 phase diesel genset comes fitted with a control panel for clear monitoring of load, run hours, and general performance, and all of our 3 phase generators in this range operate at 50Hz, making them suitable for UK installations and export markets that use this frequency standard.
