P-GRID Hybrid Power System

Only six litres.An hour.

So what is your diesel engine costing you?

A conventional diesel generator drinks fuel all day, even at part load. The P-GRID runs on roughly 6 litres an hour by letting its battery do the heavy lifting and firing the engine only when it needs to.

A new class of site power

Swap out the old diesel generator.

The P-GRID brings battery-hybrid technology to temporary power. The engine runs only when it is genuinely needed, so you cut fuel, noise and emissions without giving up the dependable output your site relies on. It is the modern replacement for a standalone diesel set.

See what you save. A like-for-like diesel set runs flat out whether the site needs the power or not. Set your runtime below to compare the weekly fuel bill against the P-GRID, and see the difference in pounds, litres and emissions.

The system

A generator that
knows when to rest

The P-GRID is an advanced hybrid power system engineered for demanding temporary power environments such as construction sites, infrastructure projects, utilities and remote industrial locations.

By integrating a Stage V diesel generator with a robust lead-carbon battery pack, the P-GRID intelligently manages loads, smooths power peaks and minimises generator runtime. Designed for both on-grid and off-grid operation, it supports peak shaving, continuous operation and microgrid applications.

Its intelligent load management system automatically optimises energy use, reducing fuel consumption, emissions, noise and maintenance. With multiple external connection options and the ability to run in parallel with additional units, the P-GRID scales easily from small sites to multi-crane developments.

Built for durability and long service life, it features a rugged, low-maintenance design and remote monitoring, giving site teams full visibility of performance, usage and system health. The result is a dependable, flexible and more sustainable hybrid generator for modern construction.

Why it works

Ideal applications

Where it earns its keep

From a single welfare cabin to a multi-crane development, the P-GRID adapts to the load and keeps fuel use low wherever it is put to work.

Construction sites

Run cranes, welfare units and tools from one quiet, fuel-light source of power.

Rental fleets

A standout hire asset with built-in telemetry, low running costs and strong green credentials.

Back-up power

Holds the load seamlessly when mains or a primary supply drops, keeping critical kit running.

Residential areas

Low noise and low emissions make it suited to work close to homes, schools and offices.

Core of a microgrid

Pair it with solar or the grid and let it balance and smooth the load intelligently.

Events

Clean, near-silent power for stages, vendors, hospitality and temporary infrastructure.

Infrastructure & utilities

Dependable output for road, rail and utility works wherever the project takes you.

Remote industrial

Reliable off-grid power for locations where refuelling and mains access are limited.
