Figure 20: StorEdge Connection Unit
10. 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.
11. Ensure proper conduit sealing; inspect the entire conduit run and use standard
conduit sealants to avoid water penetration.
12.
Turn ON the StorEdge Connection Unit switch. If 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:

13. Verify that the following information appears on the LCD panel:
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.
