Step 1, Activating The System - SolarEdge Power Harvesting System Installation Manual

SolarEdge Installation Guide for Three Phase Inverters – EU – Version 1.5

Step 1, Activating the System

This section describes how to perform the initial activation stages of the
SolarEdge system.
These stages are preformed after the inverter and power optimizers have
been installed and the power optimizers have been connected to the
inverter.
►
To activate the SolarEdge installation:
1 Power OFF the Three Phase Inverter by turning off the ON/OFF switch
at the bottom of the inverter and the DC switch of the main circuit
board (if exists).
2 Turn on the AC to the inverter.
3 If the site is installed with an external DC switch between the power
optimizers and the inverter(s), then turn it ON. A message similar to the
following message appears on the inverter's LCD panel:
V a c [ v ]
2 3 0 . 7
< P _ O K
4 Verify that P_OK appears, which indicates a connection to the power
optimizers, and that at least one power optimizer is sending monitoring
data. The number 0 indicates that no power optimizer has been paired
to this inverter. If you are re-pairing the power optimizers and inverters,
the number indicates the number of power optimizers that have been
paired in the past. If P_OK does not appear, check the power
optimizer, strings and DC input connections.
5 If the inverter is connected to the SolarEdge Monitoring server, verify
that S_OK appears. This denotes that the connection to the server is
successful.
6 Verify that the Vac [v] on the LCD panel specifies the grid's correct
AC output voltage, in Volts.
