Cellular Modem Installation Guide
This installation guide describes how to install and set up a GSM cellular modem for use as a communication gateway for the
SolarEdge device (inverter or Safety and Monitoring Interface [SMI]).
What’s in the Box
GenPro 20e SQB GSM modem
GSM antenna
Universal power supply
15-pin / 9-pin serial cable
15-pin to 3-wire (RXD,TXD and
GND) serial cable
Modem manufacturer instruction
sheet
This installation guide
Physically Connecting the GSM Cellular Modem
1Connect the antenna to the modem.
2Remove the SIM card cover, insert
a SIM card into the modem and put
the SIM card cover back.
NOTE: A SIM card is not supplied with this product. You must
purchase a SIM card and an appropriate GPRS data package from
your GSM service provider separately. Confirm with your GSM
service provider that the SIM card is unlocked for GPRS data
usage.
For an inverter with an external RS232 port, continue
to step 3. For other devices, continue to step 4.
3When using a SolarEdge inverter, connect the modem to
the inverter using the RS232 port. Use the 15-pin / 9-pin
serial cable provided.
Figure 1: Inverter RS232 Connection
Continue to step 8.
4When using a SolarEdge SMI or an inverter without an
external RS232 port, be sure to turn the AC power off and
wait five minutes.
5 Open the SolarEdge device cover, as instructed in the
device manual.
6Open gland #1 located on the bottom of the SolarEdge
device, as shown in Figure 2. Figure 2 shows the SMI as an
example. The procedure is similar for the inverter.
Figure 2: Cable Gland Location on SMI
The smallest hole is for RS232 cable insertion. The
SolarEdge device glands come presealed from the
factory. Remove the sealing to insert the cable.
CAUTION:
If a gland is opened and not used, then make sure to reseal it.
Otherwise, it may degrade the device’s ingress protection and
void the warranty.
CAUTION:
The internal side of the gland includes an o-ring, which should
be used to ensure proper sealing.
7Connect the modem to the SolarEdge device through
the RS232 connector, which is the nine-pin terminal
block connector on the right side of the communication
board.
Figure 3: GSM Cellular Modem Wire Connection
The GSM kit comes with its dedicated cable. Locate
the hole specified for RS232 cable and insert the side
without connector of the RS232 cable into the device
through the gland. Connect its wires as follows:
Insert the Tx-marked wire into the terminal block
TX pin.
Insert the Rx-marked wire into the terminal block
RX pin.
Insert the G-marked wire into the terminal block
Gpin.
8Connect the other side of the RS232 cable to the GSM
modem.
9Connect the power supply to the modem and to an
electrical socket.

NOTE:
If the S_OK indication is not displayed, then perform the following:
Use another method (unrelated to the SolarEdge device) to check whether the network and modem are operating properly. For
example, connect a laptop to the Ethernet modem and connect to the Internet.
Check the Server Communication status screen by short pressing the LCD button. If the Modem Disconnected message (appears
only in firmware version 2.250 and above) is displayed, verify the physical connection between the modem and the SolarEdge device
or reset the GSM modem.
Check the Server Communication status screen by short pressing the LCD button. If the Absent or Locked SIM message is displayed,
check that the SIM card is fully inserted in the right direction.
Verify with your GSM network provider that the SIM card is not locked for GPRS data usage.
Verify that there is cellular reception near the GSM modem.
Check the configuration of the SolarEdge device.
S_OK: Verify that S_OK appears on the panel to
indicate a functioning connection to the SolarEdge
Monitoring Server, which was validated during the
last two minutes.

Appendix A –Multiple SolarEdge Devices, RS485 Bus and GSM Modem Connection
This configuration enables you to connect multiple
SolarEdge devices through the same bus in a master/slave
configuration. In this configuration, only the master is
physically connected to the Internet through the GSM
modem.
Recommended Cable Type and Distance:
RS232:
Cable Type: Supplied with kit.
Max. Distance: 15 m / 50 ft (supplied cable plus
extension).
RS485:
Cable Type: Four-conductor cable (with RJ11
connectors for older communication board
versions).
Max. Distance: 1,000 m / 3,000 ft (from the
master SolarEdge device).
Figure 5: Connecting Multiple SolarEdge devices
Additional Required Equipment:
Four-conductor cable (not supplied by SolarEdge).
This section assumes that GSM modem communication is already
configured, as described above.
►RS485 bus terminations:
The two SolarEdge devices at the ends of the chain (meaning the first
SolarEdge device and the last SolarEdge device) must be terminated by
switching a termination dip-switch inside the SolarEdge device to ON.
The switch is marked SW7, as shown in Figure 6.
►Configuring the SolarEdge devices using the user
buttons:
1 First, configure the GSM cellular modem connection, as described
above.
For each of the slave SolarEdge devices, perform the remaining
steps in this procedure.
Figure 6: RS485 Termination Switch
2 Verify that the SolarEdge device’s ON/OFF switch is OFF.
3 Press the LCD Light button once to turn ON the backlight.
WARNING!
If the SolarEdge device worked properly before this action, the adjacent message
is displayed.
This message is displayed until the DC is safe. The default safety voltage is 50 V.
Do not open the cover or open DC connectors until the voltage is indicated as
safe or until at least five minutes have passed.
4 Short press the LCD button to scroll through the
informative screens to show the ID status window and
verify the CPU firmware version. Verify whether it is
below or above version 2.250.
