Step 2, Pairing Power Optimizers To The Inverter - SolarEdge Solar Inverter Installation Manual

Verify that the following information appears on the LCD panel:

P_OK: Appears only upon first telemetry reception from the power optimizers. Indicates
connection with the power optimizers and that 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: Appears only upon first telemetry reception from the power optimizers. Indicates the
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 portal 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 Appendix A: Errors and Troubleshooting on page 50.

Vac [V] - the grid 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 ± 3V 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.

Step 2, Pairing Power Optimizers to the Inverter

Once all connections are made, all the power optimizers must be logically paired to their inverter. The
power optimizers do not start producing power until they are paired with an inverter. This step describes
how to assign each inverter to the power optimizers from which it will produce power. Perform this step
when the modules are exposed to sunlight.

Turn the inverter ON/OFF switch to ON within 5 seconds. If you wait longer than 5 seconds the
inverter exits the pairing mode.
The following message is displayed indicating that the inverter is performing the pairing.

Wait for the completion of the pairing (remaining seconds is 0). If pairing fails, an error is displayed.
In this case, repeat the pairing steps. If the problem persists, contact SolarEdge Support.
When pairing succeeds, the following message is displayed:
