System Overview
The SolarEdge power conversion solution optimizes energy production of all types of solar photovoltaic (PV) while
reducing the average cost per watt. The following sections describe the various components of the system.
SolarEdge Power Optimizer
SolarEdge power optimizers are DC-DC converters connected to PV modules to maximize energy recovery by
performing independent monitoring of maximum power point tracking (MPPT) at the module level.
power optimizers regulate the tension on the chain at a constant level, regardless of the length of the string and the
environmental conditions. power optimizers include a safety voltage function for automatically reducing the output of each
power optimizer to 1 Vpp in case of failure or when disconnected from the inverter or when the ON / OFF switch of UPS is
turned off. Each power optimizer also transmits module performance data on the DC power line to the inverter. Two types of
power optimizers are available:
•
A power optimizer added to the module - connected to one or more modules
•
An integrated power optimizer module - integrated in a module
SolarEdge inverter
The inverter SolarEdge effectively converts the DC power from AC power modules which can be introduced into the main
AC terminal site and from there to the power line. The inverter also receives each power optimizer surveillance data and
transmits them to a central server (the SolarEdge Monitoring Portal; this requires an 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 on current and past performance of each module individually and on the system
as a whole.
