To activate the emergency back-up power supply during a power failure, press the ON/OFF button for 1 second until you
see PF followed by 3 hyphens. Press the ON/OFF button again for 1 second to activate the back-up operation.
If the emergency power outlet has been used during a power cut, remember to switch it back to grid operation mode
once power is restored to your home. For safety reasons, the battery system will not switch back automatically to grid
operated mode after the power back-up function is used.
The MODE indicator light will be orange to show that the battery is still in back-up mode and the GRID light will be
blinking green to indicate that it is waiting for power restoration. To start normal operation, first press the ON/OFF button
for 1 second until you see 5 hyphens in the display. Now, press the ON/OFF button again for one second to start the
battery. You should see a solid (non flashing) number between 0.0 and 2.0 in the display.
Good to know: The emergency back-up power outlet will only work if there is sufficient charge in the battery. A lower
discharge limit can be set which will guarantee that the battery will always have a minimum remaining level of electricity
stored in case of a power cut. However, this will also reduce the available capacity for day to day power cycling.
If you experience frequent power cuts in your area you can set the lower discharge limit to an appropriate level.
Example: If you want to ensure that you are able to charge your laptop (50 W) and keep your router (30 W) running
during a power cut you need 80 Wh (watt hours) of storage to bridge one hour without power. As 80 Wh equal 1.% of the
battery’s capacity, you would have to set your lower discharge limit to
greater than 1% to ensure there is backup power
to remain connected for one hour. If you set your lower discharge limit to 5% you could charge your laptop and stay
connected to the internet for 5 hours.
