5.5 Internet connection problems
The Redback inverter will perform best when it is permanently connected to the internet. An internet connection enables the
inverter to send data to the Redback cloud, where you can use the Redback app or portal to view performance and fine tune
the system.
Occasionally, the inverter may lose internet connection and be reported as “offline”. Ethernet connected systems usually self-
repair after a system restart. Wi-Fi problems usually require that the installation details be updated.
The most common causes of “offline” reports are:

REMEDY
Ethernet
Wi-Fi
Change of Internet Service Provider e.g., Telstra,
Optus, TPG, Dodo etc
 
Ethernet: Restart the system
Wi-Fi: Restart and re-onboard
New router or modem


Change of Network name or SSID


Change settings in ADSL modem


Changed Wi-Fi or Network password

Wi-Fi: Restart and re-onboard
Too many users or devices on your home Wi-Fi
network

Limit users or devices; upgrade Wi-Fi router;
connect using ethernet.
Wi-Fi signal is weak or variable due to obstructions
or distance between the inverter and your Wi-Fi
router’s antenna.

Experiment with Wi-Fi router locations; use a
Wi-Fi extender; connect using ethernet.
Attempting connection to a 5Ghz Wi-Fi network

This equipment is not compatible with 5Ghz Wi-Fi
networks. Use a 2.4Ghz network or ethernet.
5.6 Inverter unexpected shutdown
The inverter may shut down or isolate itself from the grid if it detects conditions that may cause damage to the inverter or
batteries; or create an unsafe situation. Incident causes can be diagnosed by examining the data available on the portal.
Unexpected shutdowns may occur in the following circumstances:
