2.4 kWh SMA battery backup system


Blackout proof your home!


The 2.4 kWh SMA battery backup system can provide your house or small business with up to 5 kW of backup power and 2.4kWh of energy during blackouts. By connecting the 2.4 kWh SMA battery backup system to important loads within the building such as lighting and refrigeration, you can remain unaffected during blackouts and brownouts. During moments of poor power quality or unavailability, the 2.4 kWh SMA battery backup system switches your connected lights and appliances over to battery power. 


Additionally, if you have a SMA grid connected solar power system installed, power being produced by the solar panels will continue to feed into your house - extending the length of time you can remain independent of the power grid! 


Note: Inverter brands other than SMA will still work as grid connect systems but cannot be connected to the SMA battery backup system directly.
