Chapter 5: Commissioning the Installation
The following workflow describes how to activate the system, commission the installation and verify the
proper functioning of the system.

Step 1, Activating the System

1
Verify that the inverter ON/OFF switch is OFF.
2
Activate the inverter according to the activation instructions supplied with the inverter.
3
Turn ON the AC breaker.
4
Turn ON the AC/DC Safety Switch. If an additional external DC switch is installed between the power
optimizers and the inverter(s) then turn it ON.
A message similar to the following appears on the inverter LCD panel:
V a c [ v ]
2 4 0 . 7
P _ O K :

Verify that the following information appears on the LCD panel:

P_OK: there is a connection to the power optimizers and at least one power optimizer is
sending monitoring data. If P_OK does not appear, check the power optimizer, string and DC
input connections.

000/000: number of power optimizers that have been paired to this inverter. At this stage, the
number should be 000, since no power optimizers have been paired.

S_OK: the connection to the SolarEdge Monitoring server is successful (should appear only if
the inverter is connected to the server). If S_OK is not displayed and the inverter is connected
to the server, refer to Verifying the Connection on page51 for troubleshooting.

Vac [V] - the grid's AC output voltage. Verify the correct value.

Vdc [V] - the DC input voltage of the longest string connected to the inverter. There should be a
safety voltage of 1V for each power optimizer in the string.
NOTE:
A measurement error on the inverter LCD of ±3 V is acceptable.

Pac [W] - the AC output power. Should be 0.0 since the inverter is OFF.

OFF – The inverter ON/OFF switch is in the OFF position.
