8. Make sure the backed-up loads AC breaker is UP.
9. Close the StorEdge Connection Unit cover: Attach the cover and secure it by tightening the six screws
with a torque of 1.2 N*m / 0.9 ft.*lb.
10. Ensure proper conduit sealing; inspect the entire conduit run and use standard conduit sealants to
avoid water penetration.
11. 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 ]

P _ O K :

12. Verify that the following information appears on the LCD panel:
P_OK: Appears only upon first telemetry reception from the power optimizers. Indicates
l
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 portal is successful (should appear only if the
l
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 79.
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.
