Getting the best from your backup circuit
Your inverter includes a backup circuit that is activated during a grid
outage and powered by the system batteries and or solar. The Inverter
can provide power to the backup circuit if:
• Power is available from batteries or solar, and
• Total household, continuous power demand is less than
10kW, and
• Total power demand is less than the power available from
batteries and solar.
Generally, you should connect and use the minimum number of devices at any one time.
Only essential or low consumption devices or appliances should be connected to the backup circuit. Devices that require high
currents should not be connected as they may trip the inverter or rapidly discharge the batteries. The table below lists the
suitability of common devices.
The inverter can fulfil demand of 16.5kW for up to 60 seconds: this is useful for devices that have high starting power, but low
power demand when running.
The inverter will reduce power output below -10
°
C or above 45
°
C ambient and shut down above 60°C.
If the system battery reaches minimum State of Charge during a grid outage the inverter will attempt to fulfil the backup circuit
demand from Solar- if demand exceeds available solar power the inverter will shut down automatically. Solar is unpredictable—
it varies with cloud cover—so this situation is best managed by minimizing devices in use.
Refrigerators and freezers Critical Medical Devices
Fans Air conditioners & heaters
Small, occasional use, plug-in appliances e.g.,
microwaves, kettles, toasters
Ovens & cooktops
TVs, radios, telephones Home theatres and Projectors
Computers, tablets, routers Hot water systems
Mobile phone or small-device chargers Spas, saunas, pool pumps
Household tank water pumps Battery chargers & corded Power tools
Low-energy LED or CCFL lighting Incandescent or high-power lighting
AVOID INVERTER SHUTDOWNS! The total
power load matters: simultaneously
running a kettle, toaster, microwave, large
fridge, TV, and a few lights can easily
exceed the allowable power delivery, and
an inverter shutdown will occur.
Solution: Minimise devices in use.
