Generators, hybrid systems and battery energy storage for sites without a mains supply. Diesel, LPG and zero emission options, from portable, mobile and industrial generators to hybrid generators, battery energy storage systems and lighting towers. Most of the range is Pramac; see our construction site power guide for help choosing.
Site power ranges from a single generator to hybrid and battery systems feeding a distribution network. The right answer depends on the load profile — peak demand, and how much of the time you are anywhere near it.
A generator running at a fraction of its rating burns fuel inefficiently and wears badly. Sizing on peak demand alone usually produces a machine that spends most of its life underloaded.
Where demand varies with long quiet periods, battery storage covers the low load and the engine runs only to recharge. That cuts fuel, noise and emissions, and matters increasingly where sites have air quality or noise conditions attached.
On the load profile rather than peak alone — how much power is needed, and how much of the time. Oversizing wastes fuel and wears the machine.
A generator paired with battery storage. The battery covers low demand and the engine runs only to recharge, cutting fuel, noise and emissions.
Where demand varies with long low-load periods, or where noise and emissions conditions apply to the site.
We supply Pramac, Armorgard, Wolff Onsite, Ampd and Dumarey. Ranges vary, so check the brand page for the full listing.
