Enecsys SMI-S240W-72

Overview

The Enecsys Micro inverter, installed on the rack at the back of each solar module, offers a unique and excellent value proposition compared to conventional string or central inverters. Benefits include significantly increased energy harvest and lower lifetime cost of solar photovoltaic systems, increased inverter reliability to match the life of solar modules, comprehensive web-based monitoring and a communications system that analyzes and reports the performance of each solar module within the PV array to enable system performance optimization, simplification of PV array design, ease of installation, and improved safety.

Enecsys Micro inverters

Enecsys’ innovative and patented solar micro inverters have 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 degrees C to +85 degrees 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.

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.

Certification

The Enecsys Micro inverters operate with both European (220-240Vac, 50Hz) and North American (110-120Vac, 60Hz) electricity grids. Products are presently CE certified and country specific requirements, including VDE V 0126-1: 2006 compliance, are achieved through the use of specific Enecsys installation products. The North American market certification, UL1741, is expected imminently.

Installation

The Enecsys solar micro inverter enables simplified PV array design and installation. For rooftop installations, solar modules can be installed on any available space resulting in ease of design of the PV array compared with conventional inverter installations where design of the PV array module placement is complicated by shading issues. This makes solar installations easier, faster and cheaper to implement. Also, installers do not need to match the performance levels of adjacent solar modules in order to optimize the performance of the PV array
