Three Phase System

three phase voltage optimisation
The small three phase voltage optimisation system used award winning technology, which has been widely utilised successfully by for large commercial properties and adapts this for use in smaller business and industrial sites.

The three phase system is is suitable for businesses with a typical annual electricity consumption of up to 300,000 kWh per year.

Businesses with electricity consumption higher than this are likely to be better suited to the commercial Powerstar voltage optimisation systems.

The 100 Amp unit allows users with three-phase installations to achieve substantial energy, carbon and financial savings by balancing the three-phase supply and providing the optimum incoming electrical voltage for all loads at any given time, without affecting the businesses operational capacity.

Previously many businesses may have found commercial, three phase voltage optimisation too large and costly for their site, and smaller, single phase or domestic voltage optimisation systems not suitable for their three phase supply.


The smaller three phase voltage optimisation system has been designed and engineered specifically to address these underlying extremes between small and large installations to open up the benefits and savings of voltage optimisation to SME’s in a range of industries.



An average commercial site can expect to reduce energy consumption by an average of 12%-15% through the installation of a VO4 system, other benefits include:

  • Operates on all circuits, 24 hours a day, 7 days a week
  • Extends lifespan of electrical equipment
  • Simple installation – No need to change electricity supplier
  • Manufactured to the highest British standards and efficiency
  • Works with and improves the efficiency of heat pumps and PV systems
  • Compatible with energy saving and generation systems such as PV and wind turbines
  • No maintenance required
