Verifying The Connection - SolarEdge Home Gateway Installation Manual

Verifying the Connection

1
Verify that the S_OK LED is ON, which indicates the
communication with the SolarEdge portal is established. This
may take up to five minutes. If the LED does not light up, refer
to Appendix A: Troubleshooting on page 18.

After device discovery, verify that the yellow (Link) LED blinks
and indicates the correct amount of slaves, as described in the
following illustration.

Verify signal strength: Check that at least two RSSI LEDs are ON,
which indicates medium signal strength. If only one LED is ON,
the signal strength is Low. Consider relocating the home
gateway closer to the inverter to improve reception. If all RSSI
LEDs are OFF, place a SolarEdge ZigBee repeater (sold
separately) between the home gateway and the inverter. Refer
also to Troubleshooting Ethernet Connection, below.
