Troubleshooting

Inverter unexpectedly or frequently shutting down

The inverter may shut down or isolate itself from the grid if it detects supply conditions that may cause damage to the inverter;
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:
CAUSE
A grid outage (blackout) is occurring
Grid supply is not of acceptable
quality, as defined by AS/NZS 4777.2.
If internal temperature is greater than
60 C.
°

Multiple inverter installations

Your installation may include 1-3 SI-series inverters, usually connected to different phases, and these inverters operate
independently except in one situation: if any inverter encounters a fault and needs to shut down, then the other two inverters
will also shut down immediately. When the first inverter recovers, or is isolated from PV and the Grid, the other two inverters
will restart.

Internet connection problems

Occasionally, your inverter may lose internet connection and be reported as "offline". Ethernet connected systems usually self-
repair after a system restarts. 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.
