Enecsys - Inverter Reviews

About Enecsys

Enecsys Limited was a privately owned UK company founded in 2003 that manufactured microinverters and provided related monitoring services. 

The firm had support from several private equity investors such as CPE (Climate Change Capital Private Equity), Winsome Capital, Good Energies, and Cambridge University.

Although well-supported, the company hit the skids. Enecsys UK Limited entered into administration on 30 January 2015 and the company's assets sold off. Commencement of wind-up was on 1 February 2016 and the firm was dissolved on 8 July 2021.

A bit of good news for Enecsys microinverter owners is while the company's monitoring service shut down, an owner co-developed an application to monitor his own panels - and even bought the Enecsys domain name. The new monitoring service was made available to others for an annual subscription fee, and still appears to be operating today. 

Enecsys Microinverters In Australia

Two series of microinverters were available: the Enecsys Single series and the Duo. Both were attached beneath the panels of a solar array - one microinverter per panel in the Single series and one per two panels in the Duo series. The Enecys Single had a maximum AC output capacity of 225W, and the Duo, 450W. 

Enecsys claimed their microinverters could operate within a temperature range of -40 to +85 degrees C without degradation of a peak efficiency of 94.5 percent. The units also used a patented energy storage technique featuring long-life thin film capacitors instead less reliable electrolytic capacitors.

Warranty Details

Enecsys offered a twenty-year limited repair, replacement or refund warranty. However, the company also claimed a lifetime matching that of solar modules -25 years, and this could also be considered a warranty.

But after going into administration, Enecsys was no longer in a position to honour its warranty obligations. Enecsys microinverter owners were advised they may be entitled to claim as unsecured creditors. But for Australian owners, the company that supplied and installed these microinverters (or imported them) is also on the hook for warranty.
