Voltage Optimisation systems – reduce your energy consumption

Voltage optimisation from Powersun


Voltage Optimisation is an energy saving technology installed in series with the main electricity supply. This systematically optimises, regulates and cleans the incoming power, and brings the voltage supplied into a building in line with what is actually required by all the equipment in the plant or office.  Savings are between 10% and 25% of your electricity bill.

Many systems are just a step down transformer, and while this will have some effect, the overall energy consumed remains much the same and savings will only be a few %.

Powersun is an official supply partner of Powerstar in Sheffield. The Powerstar system is patented and works via a 3rd winding in the transformer. This allows very predictable and more importantly, GUARANTEED savings of between 5% and 25%.


How it works

How voltage optimisation works


If your supply voltage is fairly constant, we will recommend a Powerstar Lite system, with a fixed optimised voltage.


If your voltage fluctuates, the Powerstar MAX will offer higher savings, as it can respond automatically to supply changes and retain the operating voltage at the optimum level all the time.

[tab title=”Is Powerstar LITE right for my business?”]

The site has a low voltage (LV) supply only
The site has a high level of incoming voltage
The site has a stable voltage profile
Powerstar LITE fixed voltage optimisation systems have made significant savings in manufacturing and industrial sites, education facilities, office buildings and retail outlets.
[tab title=”Is Powerstar MAX right for my business”]

The site has a low voltage (LV) supply only
The site has a high level of incoming voltage
The site has a volatile or fluctuating voltage profile
The site has critical equipment on site that requires additional security
The site has high night loads as electricity is still consumed as other uses reduce demand
Powerstar MAX variable voltage optimisation systems have provided significant savings for healthcare estates, hotel and leisure facilities, supermarket chains, data centres and cold storage sites.


[icon id=”briefcase”] What’s The Deal?

  • We will guide you through the process from start to finish, beginning with analysis of your Half Hourly data and your site voltage, followed by free installation of an energy analyser. After this, you will receive a firm offer detailing the savings and the Powerstar guarantee.
  • We’ll then work with one of our installation partners to supply, install, commission and support the new VO equipment.
