10 Inverter
Two types of power optimizers are available:
module add-on power optimizer – connected to one or more modules
smart modules - the power optimizer is embedded into a module

Inverter

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).
Some inverters are available with an optional DC Safety Unit. The DC Safety Unit has a
manually operated switch for disconnecting the DC power of a SolarEdge system.
The DC Safety Unit is located below the inverter and is connected to the inverter with
AC and DC wires.

Monitoring Platform

The monitoring platform enables monitoring the technical and financial performance of
one or more SolarEdge sites. It provides past and present information on the system
performance both at the system and module levels.

Installation Procedure

The following is the procedure for installing and setting up a new SolarEdge site. Many
of these also apply to modification of an existing site.
