card supplied with the inverter.
2Press the LCD light button short presses until the screen below
is reached.
ID: # # # # # # # # # #
DSP1/2:x.xxxx/x.xxxx
C P U : 0 0 0 3 . 1200
Country:XXXXX
3Check the CPU version number. If lower than 3.1200, upgrade
the inverter software as described below; otherwise close the
inverter cover and proceed to Configuring the Inverter Using
the LCD Light Button on page 16.
NOTE
Only inverters with version 3.xxxx can be upgraded.
►To upgrade the inverter software:
1Disconnect the AC power to the inverter and wait 5 minutes.
2Open the inverter cover as described in its manual.
3Insert the firmware upgrade card supplied with the kit into the
card slot labeled on the communication
board.

Installing the Antenna and Cable
1Connect the antenna to the mounting clip, and tighten by
screwing the antenna to the clip.
Figure 2: Connecting the antenna to the mounting clip
2Attach the mounting clip with the antenna vertically to the top
of the inverter. You may attach the clip to the heat sink fins or
the inverter side.
Figure 3: Antenna mounted on the inverter
If not mounting the antenna on the inverter, install the clip on
the wall using two screws (not supplied). The antenna must be
vertical and have a radial clearance of at least 2.7"/7 cm from
metal surfaces.
3Route the antenna cable along the inner fins or the inverter
side, in the bracket. Make sure the cable is not hanging loose
outside the inverter enclosure.

7Insert the rubber seal with the cable into the gland body and
reconnect the gland to the inverter. Tighten the sealing gland.
8Pull the excess cable into the inverter so that the cable can be
attached to the inverter communication board (see Figure 10).
Mounting the Modem in the Inverter
NOTE
If you intend to use the RS485 communication and termination is
required, adjust the termination DIP switches before installing the
cellular modem, as the DIP switches are inaccessible when the
cellular modem is installed.
NOTE
Make sure that the inverter version is 3.1200 or higher before
installing the modem, otherwise the cellular communication may
be inoperative and the inverter will not start up.
1Loosen the upper-right screw attaching the communication
board to the standoff.

2Attach the supplied holder to the communication board and
use the removed screw to fasten the holder to the board.
Figure 8: The holder installed on the communication board
3Locate the cellular modem in its place on the communication
board, as shown in Figure 9.
Follow these guidelines:
Use the supplied holder to position the modem with the
correct orientation and stabilize it.
Plug in the modem making sure that all pins are correctly
positioned in the modem connector, and no pins are left
out of the connector.

Setup mode if no buttons are pressed for more than two
minutes.
Verifying the Connection
The modem communicates with the SolarEdge monitoring portal
every several hours and sends all monitoring data accumulated since
last communication.
1Check the server communication status screen:
S e r v e r : C e l l <S_OK>
Status: <OK>
S i g : 5
< E r r o r m e s s a g e >
Server: The method of communication to the SolarEdge
monitoring portal. Should display Cell.
Status: Displays OK if the inverter established a successful
physical connection to the Cellular modem.
S_OK: The last communication to the SolarEdge
monitoring portal was successful (appears if the inverter
is connected to the portal). If S_OK is not displayed, refer
to Troubleshooting, on page 19).
Sig: The signal strength, received from the cellular
modem. A value between 0-5, (0 = no signal, 5 = excellent
signal).
Error message per communication connection status
failure (Refer to Troubleshooting, on page 19).
2Close the inverter cover as described in its manual. Verify
proper cover fastening to ensure sealing.
