Battery Backups guarantee power during outages. While grid power is available the batteries are charged. When the batteries are full the system shuts down until there is an electrical outage which triggers the backup system to initiate and power is restored. The amount of power available depends on the amount of batteries. When grid power comes back the system automatically switches back to grid power and recharges the batteries.
Battery backup systems are reliable solutions when the grid power goes out. They are charged through the electric grid and stand ready until there is an outage. At that time they automatically switch on and provide power to the electric panel. When the grid power returns they automatically shut off and are re-charged until needed again.
