Off Grid Systems

A fully off grid system is most commercial property owners ideal solution to their annual electricity bill. To never have to bow down to the oil companies prices ever again.

Sphere Energy can offer this solution for around the price of one years electricity bill.

We combine a Solar PV, Micro wind or Micro Hydro system with a bank of batteries and a small bio fuel generator to produce enough electricity to run your business as you always have.

Essentially your property will run off battery power charged by mother nature.


The PV, Wind or Hydro system will charge a bank of low maintenance batteries. The low voltage electricity stored in the batteries will run through an inverter to produce 230 Volts of clean green power 24 hours a day, 7 days a week, 365 days a year.

Depending on the system the batteries will require a full discharge cycle, every two weeks or so? This is where the Bio Fuel generator comes in, operated by our charge controller. This minimises the maintenance required to keep your business running without an electricity bill.

The amount of batteries depends on your electricity demand. The size of the PV, Wind or Hydro depends on the amount of batteries that require charging. The size of the Bio Fuel generator depends on the battery bank size.

The Bio Fuel generator will be on constant standby ready to step in if the batteries start to run low because the PV, Wind or Hydro are not performing due to weather conditions.

These systems are ideal for remote buildings, from a light fitting in a barn to a fully operational commercial building to domestic properties who no longer want an electricity bill.

Most commercial buildings already have a UPS system comprised of batteries and a diesel generator. The diesel generator will just be sitting there doing nothing for years. In fact most UPS generators only ever get switched on once a year for maintenance. We see this as a massive waste of money and a huge potential for saving your company thousands of pounds each year in electricity bills.

As the diesel generator can be the single most expensive component in a fully off grid system, why not use your excisting UPS generator. Install some more batteries, PV and micro wind turbines. Turn off your connection to the national grid and say goodby to your annual electricity bills forever. We can even convert your diesel generator to run off Bio Fuel to keep the carbon emissions down.
