Chapter 1: Introducing the SolarEdge Power
Harvesting System
The SolarEdge power harvesting solution is designed to maximize the power output
from any type of solar Photovoltaic (PV) installation while reducing the average cost per
Watt. Figure 1 shows and the following sections describe the components of the
SolarEdge power harvesting system.

Power Optimizer

The Power Optimizers are DC-DC converters connected to PV modules to maximize
power harvesting by performing independent Maximum Power Point Tracking (MPPT)
at the module level.
The Power Optimizers regulate the PV string Voltage at a constant level, regardless of
PV string length and environmental conditions.
The Power Optimizers include a safety Voltage mechanism that automatically reduces
the output of each Power Optimizer to 1 Vdc in the following cases:
During fault conditions
The Power Optimizers are disconnected from the inverter
