How Does A Backup Power System Work?
How A Power Pack Works
Simply plug your electrical appliance into the backup power system and plug the backup power system into a standard 120vAC wall outlet. Once an appliance is connected to the backup power system, the backup power system will continue to using utility power until a power event or power failure is detected. Once a power failure is detected, the backup power system will instantaneously and automatically begin supplying standard household electricity to the connected appliances. Once utility power is restored, the Battery Backup System will automatically switch the appliance(s) back to utility power and immediately begin to recharge it’s internal batteries in anticipation of the next power failure.
A battery backup power system includes an integrated battery, which stores electricity at 12-volts DC. Energy stored at 12-volt DC is unable to be used by standard household appliances that require 110-120vAC to operate. Thus, the stored energy must be converted into 110-120v AC electricity. The power inverter converts stored 12vDC energy into usable 120-volt AC electricity. The AC battery charger reverses the process by converting 120v AC energy to stored 12v DC energy.
The batteries used for these applications require do not require that the batteries be fully charged or fully discharged in between uses, thus, you can use your power pack or interrupt the charging cycle at any stage during the charging cycle
