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 ] V d c [ v ] P a c [ w ]
2 4 0 . 7 1 4 . 1 0 . 0
P _ O K : 0 0 0 / 0 0 0 < S _ O K >
O F F
5
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
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.
