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 Maximum Power Point Tracking (MPPT) at the module level.
The power optimizers keep the string voltage fixed, regardless of string length and of environmental
conditions. Each power optimizer directly transmits its module's performance data over the DC power line.
Two types of power optimizers are available:
Module Add-on power optimizer – connected to one or more modules
Module embedded power optimizer – supplied 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 server; requires
Internet connection).
SolarEdge AC/DC Safety Switch
The SolarEdge AC/DC Safety Switch is a manually operated switch for disconnecting the AC and DC power
of a SolarEdge inverter.
An AC/DC Safety Switch is installed below each inverter and is connected to the inverter with AC and DC
wires.
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.
