Chapter 1: Introducing the SolarEdge Power
Harvesting System
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 each of the system's components.
Figure 1: The SolarEdge power – harvesting system components

Power Optimiser

The Power Optimisers 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.
Each Power Optimiser also transmits module performance data over the DC power line
to the inverter.

Inverter

An external The 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 monitoring platform; requires Internet connection).
An external Connection Unit has a manually operated switch for disconnecting the DC
power of a SolarEdge system. The Connection Unit is located below the inverter and is
connected to the inverter with AC and DC wires.
