Status

Also known as
Wi-Fi module faulty

This failure means the Wi-Fi module built into the inverter is defective, and the inverter reports it as a faulty Wi-Fi module. A related event message tells you that an update of the Wi-Fi module did not succeed. While the inverter is still updating the Wi-Fi module, it shows a separate status message, so wait for the update to finish before you judge the result. If the update fails, start it again. If the failure message shows up again after the retry, contact the manufacturer's Service.

c3 drafted · lead Firmware update

If the Wi-Fi module update fails, run the update again.

review note: support check: partial - Retrying the update is stated for the update-failure message (7352), but not as a mitigation for the defective module fault; the firmware update is only a retry action.

Contact Service if the update-failure message comes back after a retry.

review note: support check: partial - Contact Service is stated for a repeated update-failure message, not for the faulty-module failure itself.
