Installation Guide

P_OK: Appears only upon pairing process completion and first telemetry
reception from the power optimizers. Indicates connection to the power
optimizers and that at least one power optimizer is sending monitoring data.
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.
S_OK: The connection to the SolarEdge monitoring platform is successful
(should appear only if the inverter is connected to the server).
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 ±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.
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.
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. If the string length is
changed or a power optimizer is replaced, repeat the pairing process.

Perform pairing: Press and hold down the inverter LCD Light button for about 10
seconds. The following message is displayed:
