Inverters can also work as Uninterruptible Power Supplies (UPS) that continuously provide AC even if outside AC is interrupted (as in a blackout or power failure). This type of application continuously operates the inverter from a bundle of batteries with an AC-powered 12 Volt battery charger. Charging can also be by means of a solar charger system. (See diagram shown below) The charger must be selected to operate continuously and to be able to fully replace the charge on the battery as the inverter operates. In this configuration, the battery “floats” on the DC from the charger, not really supplying power or being charged. When outside AC fails, the inverter continues to power the appliances for the life of the battery bank. When the outside AC is restored, the batteries are recharged as the inverter continues to operate.
