VariPower - Variable speed hybrid generator power system
VariPower is a variable speed generator combined with a highly efficient battery bank. Developed, designed and built in the UK, the range includes the VariPower 10 and 20. Both provide transportable, instant power for temporary, back-up and off grid situations in any environment.
Unlike traditional generators which only run at one speed whatever the load demands, the variable speed generator is flexible and can run at any level between 900 and 2000 rpms; providing just enough power for the load and to charge/top up the batteries without any waste.
When demands are low the generator will run at just 900 rpm, providing enough power for the load very quietly and using less fuel. For times when a higher load is demanded the generator can move up in speed to anything up to 2000rpm; delivering higher amounts of power, quickly and efficiently.
The batteries within each unit act as an energy storage system; so at times of very low demand, or when completely silent power is required the batteries alone can run the load, the generator doesn’t need to start at all.
The built in intelligence of the system means the VariPower provides power in the most efficient way possible, with this functionality users can operate in the same way as a grid connection, no manual intervention is required.
The benefits of a variable speed hybrid generator
The generator is much quieter when running at lower levels such as 900 rpm reducing noise considerably. When only the batteries are supplying power the unit is silent.
The generator is only running at the level needed therefore it only uses the fuel needed for that power demand, there is no waste and costs are significantly reduced.
Because the generator only runs at the level needed, not at one constant high rate, it will not get to its service points as quickly – which will reduce overall maintenance and service costs.
Because the batteries can power low loads (for example at night time ) there are periods when the generator does not need to run at all, therefore reducing carbon emissions.
The unit can be used in a multitude of different environments with any demands, making it an ideal rental unit.
Integral forklift pockets mean the VariPower can be easily placed on a trailer or lorry and delivered to site. It is also available pre-mounted on a twin axle trailer.
Built in intelligence means the generator automatically adjusts the engine RPMs to match any loads. No manual intervention required.
Overall the unit can reduce costs on average by 56%1 compared to a standard 1500 RPM generator.

Perfect for a range of applications
This hybrid power unit has been designed to address a range of markets, from temporary sites to permanent off grid situations. It’s efficiency and flexibility makes it suitable to:
- Temporary power
- Off Grid power
- Construction sites
- Rental applications
- Disaster Relief
- Industrial backup
- Telecom BTS sites
The proprietary control system offers a straightforward way to operate and control the VariPower with simple switches allowing operation of the key features.
The display screen allows monitoring of all the relevant data from the generator, batteries and power equipment. This information can also be viewed remotely via an optional 3G internet connection allowing the reading to be seen on tablet, Pc or smart phone.
The simple design makes it perfect for use in rental and temporary environments, whilst the remote access gives the flexibility for owners to see the details on the unit from wherever they are.
VariPower uses the Perkins 403D-11G ElectropaK - a powerful but quiet 1.1 litre naturally aspirated 3 cylinder compact engine designed to meet EU Stage IIIA/U.S. EPA Tier 4 interim emissions standards.
The 3 cylinder engine is designed to meet power generation needs in both unregulated territories where extreme conditions are likely, and higher regulated territories with more stringent emissions standards.
It was selected for the VariPower due to its power density, durability and fuel efficiency. The quiet operation makes it an excellent option as part of a unit designed to reduce noise to a minimum.
