Profile: VPhase PLC is an alternative energy technology company that has developed a patented voltage optimization technology. The technology has been independently trialled and tested, ensuring that the claimed CO2 and energy savings are certainly achievable. Installing VPhase voltage optimization results in minimal disruption. No change to behavior or lifestyle required from installing a this unit. Voltage optimization is a complementary, low cost technology that can work alongside other green technology to improve energy efficiency, lower overall emissions and results in greater savings. Solar PV and VPhase voltage optimization are two complementary technologies that can benefit from being installed alongside each other, reducing the overall payback period and improving the return on investments.
