If the emergency stand-alone 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 stand-alone function is used.
The MODE indicator light will be orange to show that the battery is still in Stand-alone 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 stand-alone 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 two mobile phones (20 W) and keep your router (30 W)
running during a power cut you need 50 Wh (watt hours) of storage to bridge one hour without power. As 50 Wh
equal around 1.
% of the battery’s capacity, you would have to se
t your lower discharge limit to 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 two
mobile phones and stay connected to the internet for 5 hours.
