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 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:
V a c [ V ] V d c [ V ] P a c [ w ]
2 4 0 . 7
1 4 . 1
0 . 0
P _ O K : 0 0 0 / 0 0 0 < S _ O K >

12. Verify that the following information appears on the LCD panel:
l
P_OK
: Appears only upon first telemetry reception from the 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.
l
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.
l
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 "Troubleshooting" on page 79.
l
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. 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.
l
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.
