Product description

The 125 kVA Generator delivers steady three-phase power for construction sites, workshops, and events that need reliable power without a grid connection. With diesel power and a large integrated fuel tank, it suits sites that need to run for long stretches without depending on mains electricity, from major projects needing continuous supply to shorter-term event and workshop power needs. The enclosed canopy keeps noise down for work nearby, and the tough, weatherproof build means it can sit outside on site for the length of the job. Make, model and specifications may vary. Stocked models include but are not limited to those pictured.
  • Diesel powered, three-phase output for bigger tools and equipment
  • Standby output up to 125 kVA
  • Runs quietly thanks to the enclosed canopy
  • Large fuel tank for long runtimes between refuels
  • Tough, weatherproof build for outdoor site use
  • Suits construction sites, workshops, and events needing steady power

Product Features

The 125 kVA Generator is designed to keep sites running when there's no power on hand, or as backup when there is. It delivers steady three-phase power for heavier equipment, not just lights and tools, and the sound-reducing canopy makes it easier to run near people working. The larger fuel tank means less time spent refueling and more time getting the job done.

Key features include:

  • Diesel powered for reliable, self-contained power on site
  • Three-phase output, suited to heavier tools and equipment
  • Standby output up to 125 kVA
  • Enclosed, sound-reducing canopy for quieter operation
  • Large integrated fuel tank for extended runtime between refuels
  • Weatherproof, corrosion-resistant build for outdoor site conditions
  • Straightforward to monitor, with built-in engine and electrical protection
  • Suits construction sites, workshops, and events needing continuous power
  • Can be used as main power or as backup supply
  • Easy-access service points for straightforward maintenance

Build a Hybrid Power Solution

Pair your Diesel Generator with a Battery Energy Storage System (BESS) and Solar Platform to reduce fuel use, emissions, and site noise. The BESS stores power generated by the diesel unit and solar input, so the generator can run less while still meeting site demand.
