Evopower have been designing and building diesel generators since 2006. We offer high quality, UK designed gensets worldwide.

Using a mixture of our our own engines, Hyundai and Cummins diesel engines our variety of sets cater for prime, or backup power (standby power). We couple the generators with a variety of alternators and use a mix of ComAp or Deep Sea Electronic control panels and optional accessories such as water heaters, battery chargers or three way valves for the connection of external fuel tanks. Our vast experience in this industry ensures we choose the correct components to complement each other and finish with high quality diesel gensets.

Our units are dispatched from our large distribution, workshop and offices in Pembrokeshire, Wales, United Kingdom but we offer these on an ExWorks (EXW) basis for collection. Within the UK, we can arrange delivery to some areas, contact us if you require a quote for this. To find out more about exporting our generators, click here.

Our experienced advisors have many years of experience in the generator, machinery and equipment industries.

Not only do we offer Cummins powered ECO sets from 50kVA to 550kVA, but we also have single phase and three phase sets, powered by our own Evopower engines.

Our EVO range, which covers 8kW to 28kW 230v single phase backup generators are ideal for home or small business back up. The 230v output is more commonly needed in smaller standby diesel generators.

Also within the EVO range are smaller 3 Phase 400v gensets, which cover 11kVA to 125kVA – but all EVO sets are powered by our own Evopower engines.
