VO4HOME is a voltage optimisation device designed for use in homes and small businesses. The VO4HOME system gives immediate energy savings for the whole home.

An average commercial site can expect to reduce energy consumption ~12% through the installation of a VO4HOME unit.

Benefits of VO4HOME:

• Reduces energy bills by an average of 10%
• Operates on all circuits, 24 hours per day 7 days per week
• Quick and simple installation – no change to supplier needed
• Extends the lifetime of electrical equipment



VOLTAGE OPTIMISER is a cutting edge technology equipment that is offering incredible benefits in terms of power savings!

- All the electrical equipment you have at home are designed to operate at a specific optimal voltage. Usually there is little control over the voltage you receive and on average, voltages are far higher than they need to be, this makes many of your electrical devices waste electricity and reduce their lifetime. 

- The Electricity Authority of Cyprus (EAC) is producing a voltage range from 220 to 240Vac but the optimal voltage for the devices is 220Vac. The aim of the voltage optimizer is to let only 220Vac voltage to pass through to an electrical device, and therefore to consume only the required energy.

- Using the voltage optimizer you can save on electricity costs, reduce emissions of CO2  and  extend the lifetime of electrical equipment.

- The voltage optimizer should be installed after the meter of EAC but before the distribution board, and operate 24 hours a day 7 days per week.
