6 kVA Diesel Generator

Hire from £130.

What the 6 kVA Generator Is

This is a silenced diesel generator in the 6 kVA class - a portable power unit that runs on diesel and puts out enough steady power to keep a small event, a site cabin or a handful of power tools going all day. You'll also see it called a site generator, a temporary power unit or just a 6 kVA silenced gen-set, and it sits at the smaller end of our generator range between the battery generator and the larger 20 kVA and 30 kVA trailer-mounted units.

The unit runs a Yanmar L100AE single-cylinder diesel engine at 3000 rpm, coupled to a Linz alternator for a steady waveform. Output is 6 kVA peak / 4.8 kW continuous, available as both 110V and 230V single phase from a bank of sockets on the side panel - one 32A 230V, one 16A 230V, one 32A 110V and two 16A 110V outlets. The 25-litre tank runs for around 23 hours at three-quarter load before it needs topping up, and the whole thing starts with a key-turn electric starter rather than a pull cord.

It comes as standard on a two-wheeled site trolley with folding handles, which means one person can roll it across hard standing or grass to where it's needed. The acoustic canopy keeps the noise down to around 65 dB(A) at 7 metres - loud enough that you wouldn't want it next to a microphone, but quiet enough for a marquee or an outdoor catering area without it becoming the main event.

We've been hiring out event infrastructure from our 25,000 sq ft warehouse in Rotherham since 1999, five minutes from the M1, and we own and maintain the kit we send out rather than subbing it to a third party. Every hire includes £5 million public liability insurance, with risk assessments and method statements emailed to you or your venue before the event.

The generator goes out with a full tank of diesel as standard. For longer hires we can arrange additional fuel delivery or leave spare cans with you - just mention it when you get in touch and we'll work it into the quote. Overnight hire is available for an extra £20.

Suitability

  • Outdoors on Grass
  • Outdoors on Hard Surface

Not suitable for indoor use, mixed surfaces, or wood chip.

What It Powers

A 6 kVA generator gives you around 4.8 kW of usable continuous power. That is enough for:

  • Small PA systems and stage lighting
  • Inflatable blowers and bouncy castles
  • Hot water urns, coffee machines and catering fridges
  • Power tools, drills and site lighting
  • Battery chargers and LED floodlight banks

If you are not sure whether 6 kVA covers your setup, send us a list of what you're plugging in and we'll check the total load for you. We also carry 20 kVA and 30 kVA units for larger rigs, and the Instagrid battery generator for silent indoor power.

Sizing Your Power

Getting the right generator size matters, because if it is too small you will trip the overload breaker every time something with a motor starts up, and if it is too large you are burning fuel you do not need. A 6 kVA unit is the right call for small-to-medium outdoor setups: a couple of inflatables, a food cart, a PA and some lights, or a cluster of power tools on a site where mains is not available.

Most kit lists its wattage on a label or in the manual. Add the running watts together, then add around 25% headroom for start-up surges - motors and blowers draw more for a second or two when they first kick in. If your total comes to under 4 kW continuous, a 6 kVA generator will handle it comfortably. If you are over that, have a look at the 20 kVA or 30 kVA options instead, or give us a call and we'll size it for you.

We also hire distribution units, cable protectors, festoon lighting and LED floodlights - everything you need to get the power from the generator to where it is being used. It is all one booking, one invoice and one point of contact.

The 6 kVA unit is the small end of our generator range. If you need more power, the 20 kVA and 30 kVA trailer-mounted generators handle full stage rigs and large catering setups. For silent indoor power, the Instagrid battery generator runs without fumes or noise. We also stock distribution units, cable protectors and lighting to complete the power package - everything below goes out from the same warehouse on the same delivery.
