Troubleshooting
12.3
Internet connection problems
Occasionally, your 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 system is re-onboarded. The most common causes of
"offline" reports are:
INDICATION
Change of Internet Service Provider e.g., Telstra,
Optus, TPG, Dodo etc
New router or modem
Change of Network name or SSID
Changed settings in router or modem
Changed Wi-Fi or Network password
Too many users or devices on your home Wi-Fi
network
Wi-Fi signal is weak or variable due to obstructions
or distance between the inverter and your Wi-Fi
router's antenna.

Earth fault alarm
If the Redback system detects an earth fault:
1.
An audible alarm will sound in the inverter.
2.
The System Error LED will be solid (see also page 26).
3.
An email will be sent to Redback customer service, the
registered installer, and the system owner.
An email is also sent when the alarm is cleared.
