Enecsys - Microinverter
From Inverters
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 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.
Monitoring System
Enecsys' comprehensive performance monitoring of the PV array is highly enhanced as each module’s performance can be viewed, a capability not available with string inverters. This uniquely provides users and installers with real-time detailed information to ensure that the solar system performance is optimized over the life of the installation.
The information can be used to promptly detect performance issues and pinpoint the exact location and nature of the problem, which provides precise guidance for required maintenance, a capability not possible with string inverter systems. The micro inverter is equipped with a robust built-in wireless communication system that connects to the internet via a gateway to provide detailed performance information on-line from anywhere.
The Enecsys monitoring system has a user-friendly graphic interface that provides the following information:
- Total energy generated
- Individual panel performance
- Historical pattern of energy generation
An Enecsys iPhone monitoring application is also available. Installers can use this to monitor multiple sites located anywhere in the world, from anywhere with a mobile data connection. For each site, information is provided about the installation date, location, current weather conditions and real-time as well as historical system performance information.
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.
