Getting the best from your backup circuit

Your SH5000 inverter includes one backup circuit 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
4600W, 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 6900W for up to 10 seconds: this is useful for devices that have high starting power, but low
power demand when running.
The inverter will reduce power output above 45
If the system battery reaches minimum SoC 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
Small, occasional use, plug-in appliances e.g.
microwaves, kettles, toasters
Computers, tablets, routers
Household tank water pumps
Low-energy LED or CCFL lighting
C ambient and shut down above 60°C.

SUITABLE

Fans
TVs, radios
Telephones
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.
NOT SUITABLE

Critical Medical Devices
Air conditioners & heaters
Ovens & cooktops
