Enecsys solar micro inverters use thin film capacitors and eliminate limited life aluminum electrolytic capacitors used in other micro inverters.

Enecsys micro inverters

Enecsys micro inverters mount on the railing system behind solar modules. Solar PV systems may use one micro inverter per module, a Duo micro inverter that accepts DC input from two individual modules, or a combination of these products.

Using innovative and patented technology, Enecsys micro inverters are designed for high reliability and match the 25-year service life of solar modules. They achieve a peak efficiency of up to 96% (depending on the model) and maintain full performance in real-world operating conditions over a temperature range of -40 degrees C to +85 degrees C. In order to achieve this high level of reliability, the Enecsys micro inverter embodies three key attributes: a patented rugged topology, a component line based on high temperature rating and ruggedness, and a unique and patented energy storage technique that enables the use of thin film capacitors instead of less reliable electrolytic capacitors and the elimination of opto-couplers.

The elimination of the components known to have relatively poor reliability - electrolytic capacitors and opto-couplers – was critical to improving the lifetime and reliability of Enecsys solar micro inverters. The failure modes of electrolytic capacitors include leakage or depletion of electrolyte solution from the capacitor, which in turn causes their internal temperature to rise and performance to deteriorate at an ever-accelerating pace.
