SolarEdge Technologies provides next generation power conversion electronics that effectively remove the known system constraints across the photovoltaic energy space. Our Smart DC ASIC technology and active electronics enable cost efficiency and an increased production of clean, grid-ready energy. SolarEdge presents a unique, patent-pending distributed solar power harvesting system, comprised of the following elements:

SolarEdge Power Optimizer

The SolarEdge power optimizer is integrated into each module, replacing the traditional solar junction box. The SolarEdge power optimizers maximize energy throughput from each and every module through constant tracking of the Maximum Power Point individually, per module. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced, cost-effective maintenance. When working with SolarEdge inverters, power optimizers automatically maintain a fixed string voltage, allowing optimal efficiency of the SolarEdge inverter and giving installers greater flexibility to design optimal PV systems.

The independent optimization (IndOP™) technology allows power optimizers to be installed without the need for additional interface hardware and to operate directly with any inverter.

Each power optimizer is equipped with the unique SafeDC™ feature which automatically shuts down modules' voltage whenever inverter or grid power are shut down.


SolarEdge PV Inverter

The SolarEdge Inverter is a highly reliable DC-AC PV inverter. Because MPPT and voltage management are handled separately for each module by the power optimizer, the inverter is only responsible for DC to AC inversion. Consequently, it is a less complicated, more reliable solar inverter. The fixed string voltage ensures operation at the highest efficiency at all times (>97% weighted efficiency) independent of string length and temperature.


SolarEdge PV Monitoring Portal

A web-based application provides module-level, string-level and system-wide monitoring. The solar monitoring software automatically provides alerts for accurate fault detection, localization and remote troubleshooting at the module level. Module performance is communicated across existing power lines, so no extra wiring is required.
