Overview

The Enecsys solar micro inverter is a compact unit that converts the DC power from the solar module to AC power for supply to the electricity grid without the need for a string or central inverter. The AC output from the Enecsys micro inverter is in-phase with the electricity grid and exhibits high power quality including low harmonic distortion and near unity power factor. It maximizes the power harvested from each solar module and therefore the entire PV array. This is accomplished by performing Maximum Power Point Tracking (MPPT), an electronic technique for maximizing the power harvested from each module under varying environmental conditions, and performance monitoring for each individual solar module. Performing MPPT on each solar module ensures maximum harvest of energy even under partially shaded conditions. Degradation in the performance of any one module, due to module mismatch, shadows from trees or chimneys, or obstructions from leaves or debris, does not degrade the performance of other modules and therefore has minimal impact on the power harvested from the PV array. This typically results in improved power harvest of 5% to 20% from the solar PV system and represents a significant cost/performance advantage. The Enecsys innovative and patented solar micro inverter SMI-S240W-60 has been designed for high reliability operations, to have a life expectancy of 25 years thereby matching the life expectancy of solar modules, to operate in real world conditions from -40° C to +85° C, and achieve a peak efficiency of 94.1% for high reliability over the temperature range. 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. It eliminates the single most common cause of failure in solar PV systems, the string or central inverter, which typically requires replacement at least once over the life of the solar modules, adding significant cost.
