Internet Connection Problems; Inverter Unexpected Shutdown - Redback SH5000 Installation Manual

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:
INDICATION
Change of Internet Service Provider e.g., Telstra,
Optus, TPG, Dodo etc
New router or modem
Change of Network name or SSID
Change settings in ADSL 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.
Attempting connection to a 5Ghz Wi-Fi network

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:
CAUSE
Continuous backup circuit load
exceeds 4600W.
Backup circuit load exceeds 6900W for
more than 10 seconds.
Backup load exceeds available Battery
+ Solar power.
If internal temperature is greater than
60°C.
Grid supply did not comply with local
or DNSP requirements.
CONNECTION AFFECTED REMEDY

COMMENT
May occur when too many devices are active on the
backup circuit.
May occur when too many high current appliances are
used simultaneously, or when a large load starts up, such
as a pump.
Output is reduced above 45°C.
Check Region setting is correct.
Check voltage-drop calculations.
Tap setting on transformer may be incorrect. Contact
DNSP.
The EMS and backup circuit will operate if power is
available from PV or batteries.
