Step 2: Pairing Power Optimizers To The Inverter - SolarEdge storedge Installation Manual

11. Close the StorEdge Connection Unit external cover: Attach the cover and secure it by tightening the
six screws with a torque of 1.2 N*m / 0.9 ft.*lb.
12. Ensure proper conduit sealing; inspect the entire conduit run and use standard conduit sealants to
avoid water penetration.
13. Turn ON the S torEdge Connection Unit switch. I f an additional external DC switch is installed between
the power optimizers/ battery and the inverter(s) then turn it ON.
A status screen similar to the following appears on the LCD panel:
V a c [ V ]
2 4 0 . 7
P _ O K :
- - - - - - - - - - - - - - -
14. Verify that the following information appears on the LCD panel:
P_OK: Appears only upon pairing process completion and first telemetry reception from the
l
power optimizers. Indicates connection to 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
l
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 platform is successful (should appear only if
l
the inverter is connected to the server). If S_OK is not displayed and the inverter is connected to
the server, refer to Troubleshooting on page 87.
Vac [V]: the grid AC output voltage. Verify the correct value.
l
Vdc [V]: The DC input voltage of the longest string connected to the inverter. T here should be a
l
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).
l
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. If the string length is changed or a power
optimizer is replaced, repeat the pairing process.
1. Perform pairing: Press and hold down the inverter LCD button for about 10 seconds. The following
message is displayed:
