Powerstar voltage optimisation systems

Voltage ManagementPowerstar voltage optimisation systems are available in three variations, providing a voltage management solutions portfolio that ensures the correct engineering solution is adopted for each site to maximise savings and efficiency.

True voltage optimisation solutions such as Powerstar should not be confused with simple voltage management devices. These technologies, although providing an alternative to reduce voltage levels, do not provide the full savings and associated benefits a true voltage optimisation system will.

The solutions in the unique, award winning, Powerstar range are sumarised below, if you wish to check the validity of Powerstar for your site through a free of charge consultation, please request a site evaluation through our online contact form:


Powerstar HV MAX

Powerstar HV MAX voltage managementSummary: Amorphous core HV/LV transformer with integrated Powerstar MAX voltage optimisation.
Benefits: Average electricity consumption savings of 17%.
For use in: Sites operating a (HV) supply with conventional transformer and high voltage.


Powerstar MAX

PowerstarMAX voltage management system
Electronic-Dynamic optimisation. Maintains voltage at a constant, stable level.
Benefits: Average electricity consumption savings of 12%-15%.
For use in: Sites operating a (LV) supply with a high and fluctuating voltage profile.

Voltage management PowerstarSummary: Fixed voltage optimisation system. Provides a set level reduction across tap range.
Benefits: Average electricity consumption savings of 10%-12%.
For use in: Sites operating a LV supply with a high, yet stable voltage profile.


powerstar energy storage system

The Powerstar Virtue energy storage system can be integrated with any new or existing Powerstar MAX or Powerstar HV MAX installation. The solution harnesses the negative power (back EMF) feedback from Powerstar voltage optimisation technology to charge a storage medium. The electricity saved and stored from Powerstar to be diverted into a storage medium to be used at any time, including times of peak demand.

Powerstar Virtue

  • Summary: Energy storage solution that is integrated with Powerstar MAX or HV MAX systems
  • Benefits: Savings from VO are stored in a storage medium for use when required to reduce electricity costs and increase supply stability. Energy generated from on-site renewables can also be integrated into the storage system to make renewable energy reliable
  • For use in: Large electricity consumers, national grids and demand side operators.
