700 kVA Generators for Sale

Crossing Into Half-Megawatt Territory

At 560 kW of usable output, a 700 kVA generator comfortably crosses the half-megawatt mark, putting it in reach of applications that would leave a mid-range machine working at its limit. Sites running continuous production, large-scale cold chain storage, or critical building services tend to arrive at this rating once they have added up everything that must stay live during an outage. Our 700 kVA diesel generators are built for that reality, engineered to run hard for extended periods without drifting from their rated output.

Ask three people in the industry and you may hear this called a 700 kVA genset just as often as a generator, though the distinction is purely one of habit. Holding real inventory as a leading stockist means a 700 kVA diesel genset can typically be committed to a project and dispatched long before a made-to-order equivalent would even enter production.

An Open Build for Housed Sites

We supply our 700 kVA open generators without an acoustic enclosure, reflecting where machines of this rating usually end up. Once a site has invested in a plant room or dedicated generator building, a factory canopy adds cost and bulk without adding protection the structure does not already provide. The saving shows up twice over, first in the purchase price and again in the reduced footprint that has to be manoeuvred into position.

There is a serviceability argument too. A 700 kVA open diesel generator presents its engine, alternator, and control gear openly to whoever is carrying out routine inspections, oil changes, or fault-finding, with no enclosure panels standing between an engineer and the component they need. Ventilation, exhaust routing, and acoustic treatment then become part of the building design, tuned to the site rather than fixed at the factory. You can see how this configuration works across other ratings on our open generators page.

Handling Demanding 3 Phase Loads

A 700 kVA 3 phase generator draws on serious reserves when several heavy loads coincide, which is exactly what happens when refrigeration compressors, production machinery, and air handling plant all call for power within moments of each other. Selecting a 700 kVA 3 phase diesel generator gives site engineers headroom to absorb those overlapping demands without the voltage dips that trouble undersized installations.

A 700 kVA 3 phase genset works equally well as permanent standby cover or as extended temporary supply on a large contract, and every 700 kVA 3 phase diesel genset leaving us includes a control panel that lays out load, run hours, and operating status plainly for the people responsible for the machine. Our 3 phase generators all operate at 50Hz, making them a straightforward fit for UK installations and for export markets built around the same frequency.

Knowledge That Prevents Expensive Mistakes

Specifying at this level is where experience pays for itself, and the 50-plus years our team has accumulated in the generator industry goes into getting the load calculations, fuel provision, and installation practicalities right before anything is ordered. As an authorised dealer, our pricing on this range is the best available anywhere in the UK, with nothing given up on build quality or on the support that continues after delivery.

Because we hold stock rather than working solely to manufacturer production schedules, a diesel generator from us slots into your timeline instead of setting it. If our range of 700 kVA gensets aren’t quite the right fit for you, our neighbouring 600 kVA and 800 kVA ranges give you room to size up or down before settling on the best fit.
