Stop getting left in the dark! Simply install the Four Star 4,400 Backup Kit and you're ready to go when the utility grid is knocked out or unstable. Just decide which loads you want to run and you're back in business.

This emergency Backup Power System is a must-have during hurricanes, tornadoes and other natural disasters!

Seamless electrical coverage
This 240-volt backup power unit incorporates an inverter that monitors the grid for disruptions. When the grid goes down or is disconnected, the inverter switches to battery backup in less than a second, keeping your critical loads online until the grid comes back.

The battery banks of the Four Star Solar Backup 4,400 can be charged with grid electricity, or by generator, or by solar panels. They can also be expanded by adding additional batteries. See Battery Options below.
