Troubleshooting
Backup circuit has no power
The most common causes are overloaded circuit isolators
tripping OFF (anytime), or the battery being fully
discharged (during a grid outage). Troubleshoot using the
guide below.

The total power load matters, and it adds up fast: a
kettle, toaster, large fridge, TV, iron, and a few lights
may exceed a backup circuit's allowable power
delivery. This rule applies even when the grid is
connected.
Action
Turn BATTERY SYSTEM DC isolator ON.
Contact your installer if you suspect the Battery
System DC isolator is tripping.
On a partly cloudy day, minimise the loads on the backup circuit—the inverter
shuts down if demand exceeds the supply available from solar e.g. when the
panels are shaded. Otherwise, wait for grid power to be restored.
As above, and contact your installer if you suspect the battery is not charging
correctly.
Identify and deactivate any suspect or excess appliances. Reset the house
Backup Circuit isolator at the switchboard.
If the problem persists, contact your installer for assistance.
Reset the BACKUP AC isolator (move up). If it trips
immediately, minimise loads on the backup circuit and
try again.
Place the inverter in Bypass mode (up). This supplies
power to the backup circuit from the switchboard.
Contact your installer.
Contact your installer for assistance. Note: The Solar Supply Main Switch is
usually located on the main switchboard.
