A variable speed hybrid generator power solution

Designed and built by Energy Solutions’ in-house engineering team, the units offer true variable power from the built-in generator - it can run at any level between 900 and 2000rpm. Why is this so vital? Two main reasons - firstly, economy - it means that if the power demand is only low, the unit can run at just 900rpm, fewer revolutions mean the generator is using less fuel and creates less noise. Secondly, longevity - the unit is not going to be worked so hard - it will only be powering at the level required, therefore increasing the interval between generator services and renewals.

As power demands increase the generator will seamlessly increase its rpms to deliver the capacity needed, and reduce again as required. For periods of very low load i.e. during the night, the system will simply use the power stored in the batteries. This gives silent power when it is most needed. The applications for this are wide spread across residential and commercial areas.

There are two variations of the unit - the VariPower 10 is designed for the off grid power market as an all-in-one, static source of affordable, quiet power. VariPower 20 has been built to be a deployable, transportable power system for applications where instant, temporary power solutions are needed.

What else makes up the system? Alongside the generator is a 20kWh battery bank, either one or two 10kVA inverter/chargers and DSE Net monitoring. The system is also designed to accept renewable power, such as solar, directly into the system. All housed within a powered coated steel enclosure which is designed for being put outside in any conditions.

Managing Director Paul Holland explained why the company developed the range: “We already have a large presence in the off grid power market, but we have been approached on numerous occasions for a product which incorporates the generator within the system. The VariPower was developed to be the ultimate variable speed solution, keeping fuel costs and carbon emissions at a minimum whenever possible, and extending the life span of the generator.”
