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 Single Phase Inverter by turning off the ON/OFF switch at
the bottom of the inverter.
2
Turn on the AC at the breakers and at the AC/DC safety switch.
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.
7
Verify that the Vdc [v] on the LCD panel specifies the DC input voltage, in
Volts. There should be a safety voltage of 1 V for each power optimizer
connected to the inverter.
NOTE:
A measurement error on the inverter LCD of ±3 V is OK.
