DHCP failed or invalid DHCP configuration.

The inverter is failed to get a valid IP address from the DHCP server or the DHCP or static IP settings in the inverter are not the same as those of the router.

For this, you need to check the router and inverter configuration. Otherwise, consult your network professional to fix the issue.


Gateway ping failed.

The connection to your router is not available. So, you have to check if the router is failed while connecting. Also, inspect the switch.

Check the connection to the LAN switch or router. Inspect that the link LED at the router is lit. It indicates a phy-link. If it is lit, you need to contact your network IT professional. If it is not, replace the cable or change it from cross to straight connection.

SolarEdge Internet Reset

Direct Ethernet Connection:

If you need to reestablish an internet connection to the SolarEdge inverter, you need to conduct a power cycle of the inverter and networking components. You can follow the below simple steps to conduct this power cycle.

  • Turn the "DC Disconnect Switch" below the inverter to the OFF position. This switch looks like the black power nob.
  • Turn OFF the solar circuit breakers in your main electrical panel.
  • Now, wait for about 10 to 15 minutes for the inverter to fully power down.
  • Next, reboot or restart your home internet router.
  • Then, turn back ON solar breakers and DC disconnect switch.

Bridged Connection:

If your inverter uses a bridged setup, you can find two bridges located on-site. One bridge will connect to an Ethernet cable which is coming from the inverter and plugged into the nearest available wall outlet. Another bridge will connect to an Ethernet cable coming from the home internet router. Simply pair these bridges to each other to re-establish the internet connection to your inverter.

Disconnect the bridge from the wall socket and Ethernet connection located near the inverter and internet router as well.

Plug the bridge boxes into the same wall socket and wait for 30 to 60 seconds for the top two indicator lights to illuminate solid green. If the two indicator lights don't illuminate solid green, you need to press the pair buttons on the bottom right corner of the bridge boxes to make communication with each other.

If the two indicator lights are turned solid green, you have to disconnect bridges from the same wall socket and return them to their previous outlets and Ethernet connections.

Once they are returned to their previous outlets, the bottom light will illuminate and all indicator lights on the bridges should be green. Although, the internet connection will be established to the inverter.
