Voltage Optimisation

What is Voltage Optimisation or VO?

Typically the incoming voltage to your property will vary between 216v and 253v as agreed with the current European Legislation.

All domestic electrical equipment is designed to work within a range of 207V and 253V.

But critically the optimum and most efficient supply voltage for these appliances is 220V.

When the supply voltage exceeds 220V waste is generated, in both heat and vibration significantly reducing the life span of the equipment...

As governments all strive to achieve targets in the reduction of greenhouse gases, each VO unit installed could save over a tonne of carbon year on year. And saving electricity in the home saves 3 times as much at the power station.

How Does It Work?

The VO unit is simply connected between your Meter and your Distribution Board...

It will then intelligently optimise the voltage supply to all your electrical appliances in your property.

How Do I Save Money and The Environment?

When you optimise the voltage to your property you immediately benefit from energy saving because you are reducing WASTE in the form of heat and vibration.

Domestic savings for a typical house could be between 5% and 13%.

By using less energy you will directly reduce the amount of carbon emissions you produce - your carbon footprint.

How Is It Installed?

Installed in approx. 2 hours by a part P qualified electrician, the unit is simply connected between the electricity meter and the distribution board (or consumer unit) without any modifications to the equipment already in the property. Quickly configured and the savings start immediately.



Can It Be Used Together With a Solar PV Installation?

The Voltage Optimisation unit is designed to complement a Solar PV Installation and will optimise the voltage to the house ensuring the appliances are not subjected to the higher voltages as a result. This reduces the total load drawn from the house and means more of what is being generated by the Solar PV system can be exported! (Please contact Greenacre Renewable Energy for detailed installation instructions for these type of installations).
