Voltage Optimisation

Powerstar voltage optimisation systems are unique, patented energy saving solutions that match the incoming electricity supply to the needs of onsite equipment and returns any excess energy back to the grid by generating real negative power. Powerstar provides savings on electricity bills, reduces electricity consumption and cuts carbon emissions for businesses.


Energy Storage

Powerstar virtue harnesses the real negative power generated by the Powerstar voltage optimisation systems to charge a storage medium allowing users to save and store electricity locally and switch to this supply at times of peak demand to save money and ensure a consistent and reliable electricity supply. Powerstar Virtue can be integrated with renewable generation sources to maximise benefits.
