Chapter 1: Introducing the SolarEdge System
System Overview
The SolarEdge power harvesting solution maximizes the power output from any type of solar Photovoltaic
(PV) installation while reducing the average cost per watt. The following sections describe the system
components.
SolarEdge Power Optimizer
SolarEdge power optimizers are DC-DC converters connected to PV modules in order to maximize power
harvesting by performing independent Maximum Power Point Tracking (MPPT) at the module level.
The power optimizers regulate the string voltage at a constant level, regardless of string length and
environmental conditions. The power optimizers include a safety voltage function that automatically
reduces the output of each power optimizer to 1 Vdc during fault conditions, when disconnected from the
inverter or when the inverter’s ON/OFF switch is turned OFF. Each power optimizer also transmits module
performance data over the DC power line to the inverter.
Two types of power optimizers are available:
Module Add-on power optimizer – connected to one or more modules
Module embedded power optimizer – embedded into a module
SolarEdge Inverter
The SolarEdge inverter efficiently converts DC power from the modules into AC power that can be fed into
the main AC service of the site and from there to the grid. The inverter also receives the monitoring data
from each power optimizer and transmits it to a central server (the SolarEdge monitoring portal; requires
Internet connection).
SolarEdge Monitoring Portal
The SolarEdge monitoring portal enables you to monitor the technical and financial performance of one or
more SolarEdge sites. It provides information about present and past performance of each module
individually and about the system as a whole.
