LGP 2500 5kVA battery power pack

5kVA portable battery generator perfect for tunnels and confined areas

Developed in partnership with Light Green Power, the LGP 2500 Power pack gives you the ability to tackle demanding jobs without relying on the power grid. With zero emissions and zero noise, the 2500 is capable of outputting up to 5kW to power the most demanding of equipment: performance that has led to it being approved for London Underground use since 2012.

As legislation tightens on the use of diesel, the LGP 2500 is one of the few products that offers all of the performance of traditional generators but is approved for use in tunnels and tight spaces. Despite a compact, man-portable design, the power pack generates serious power which allows workers to carry out high-power welding up to 180A, mix concrete, or break masonry far from the grid.

Unlike a diesel generator, the Power Pack creates no dangerous fumes during use, meaning it is safe for use in tunnels and confined areas. With the highest power output in its class, the LGP 2500 is one of very few products that can replace diesel options while conforming with all tunnel and confined area requirements.

Over the last 5 years, the LGP 2500 has found use on a broad range of maintenance and upgrade works with London Underground, who value its 5kW peak for high-power jobs such as welding, grinding, concrete mixing, tamping and breaking.

Requiring no maintenance, and no fuel beyond plugging into the mains, the LGP 2500 offers a simplicity of use that is hard to beat. This simplicity is reflected in low running costs - amongst the lowest of any generator.

Designed and manufactured in the UK, and with a lifetime of over 2000 charging cycles, you can rely on the LGP power pack to offer years of service with zero maintenance.
