POWRBANK Renewable Power Generators - How do they work?

POWRBANKs integrate energy storage with diesel generators maximizing the use of battery power for the electrical load. The POWRBANK ECM will switch the load between the generator and stored energy as is most efficient. Usually the load is powered from stored energy for the majority of the time while the generator remains off. Once depleted the stored energy is quickly recharged by the generator.

– Protects the generator from low load running hours
– Minimizes generator emissions
– Conserves fuel
– Extended periods of silent power
– Extended generator service intervals


Whether its a construction site noise ordinance or a high profile sports event our Hybrid Energy Systems give you the noise-free periods you need.

Take a look at some typical generator load scenarios and how the Hybrid Energy System manages them to drive efficiency.


There are many great applications for Hybrid Energy Systems; we've highlighted some where integration of HES yields significant benefits.

How long does the battery last?

This depends on how much power you use and the rating of the HES. So, for our 30kWhr Hybrid Energy Systems unit, assuming it is fully charged when you start, you can get 15 hours at an average of 2kW or 30 hours at an average of 1kW. We use Lithium Ion batteries so that even at high discharge speeds you won’t lose available power.

How much power can I get?

We offer a range of alternative ratings that give power outputs from 5kVA to 60kVA from our standard range. We can offer bespoke energy solutions up to 300kVA.

What is the output supply voltage?

Our standard systems come with the following voltage configuration: 120V 60Hz single phase, 120/208V 60Hz three phase.

How noisy is it?

Without a diesel generator running, the energy system is inaudible. There may be some fan noise when the unit is working hard but this is only detectable when you stand very close. Acoustic Pressure: @ 3ft: Trace, @ 10ft: 0

What maintenance is required?

The energy system is virtually maintenance free. Other than making sure the unit is charged up fully and regularly during use and before being put into storage, the maintenance regime is simply that of periodic inspection.

What is the battery service life?

We use the latest Lithium Ion batteries that have an expected life of 10,000 cycles to 70% of the original capacity. So, in a scenario where the unit is at a 70% utilization rate and cycles 3 times per day, the batteries will last well over 10 years.
