Powerstar Virtue energy storage system

Powerstar Virtue is an energy storage system suitable for large energy users. It harnesses the excess voltage supplied from the grid, stores the excess and deploys it at times when the cost of power is at peak tariff.

According to the company, because most buildings receive power from the grid at 247 V and most electrical equipment is designed to work most efficiently at 220-230 V, the result is ‘wasted’ energy which the system can store and deploy.

The technology allows users to become a virtual power station, reliably forecasting how much power will be available at all times and enabling decisions to be made on when stored energy should be used.

The system can be integrated with on-site renewable energy generation such as solar and wind to combine the energy saved from the system with that generated from the renewable energy source.

The system can also eliminate the need for inverters on renewable installations, which can reduce the cost and therefore improve the return on investment.

Sites will also benefit from reduced harmonics, voltage phase balancing, improved power factor and reduced maintenance costs of electrical equipment.
