About PV inverter communication failed
Power down the devices you are working on before opening any covers or working with any wiring. Inverter: See Safety Precautions. Battery: Once the inverter has been powered down, turn off any battery toggle switches.
Navigate to the server. Set the server channel to LAN , if this has not already been set. Optional: If the local network is not DHCP enabled, you may need to enter the LAN Conf menu to.
Once the Ethernet cable has been installed, the device may need to be configured to get a proper connection to the SolarEdge Monitoring server.
Connect to the device using SetApp. Navigate to Monitoring Communications. If an Ethernet is not selected, tap the Change Configuration.Verify if there is a communication issue on the inverter by checking the inverter LEDs. A steady blue light indicates the inverter is communicating. Connect to the device using SetApp.

6 FAQs about [PV inverter communication failed]
What causes a solar inverter to fail?
Inverter failure can be caused by problems with the inverter itself (like worn out capacitors), problems with some other parts of the solar PV system (like the panels), and even by problems with elements outside the system (like grid voltage disturbances). An inverter failure is when the inverter develops faults that cause improper functioning.
What happens if a PV inverter fails?
Increase the number of PV modules connected in series to the inverter. The protection for the DC circuit is triggered. This occurs if the inverter input accidentally disconnects, the three phases of the grid become unbalanced or if there’s a fault on a circuit in the inverter. Turn off the AC output switch, then the DC input switch.
Why is my PV system not feeding into my inverter?
If this message is repeated frequently, contact the SMA Service Line. The inverter has detected a ground fault in the PV array. As long as the fault exists, the inverter will not feed in. Check the PV system for ground faults ( > Checking the PV System for Ground Faults). The PV array voltage is too low.
What should I do if my SMA inverter is not working?
Contact the SMA Service Line. The communication version of an inverter is not supported or the device combination is invalid. Contact the SMA Service Line and request the latest firmware package, if necessary. Communication with one or several inverters is no longer possible. Check cables and inverters for loose connectors or damage.
How do I troubleshoot my inverter?
Troubleshooting Options: Inspect Communication Cable: Investigate the communication cable connected between the inverter and the battery. Go through all the plausible nooks and corners to suspect if they are securely connected and if there is no damage.
What is an inverter failure?
An inverter failure is when the inverter develops faults that cause improper functioning. Some of the common reasons for inverter failure are: Let’s delve into these issues. Electrolytic capacitors in inverters are temperature-sensitive.
