A&T Power Systems–Grid-Connected with Battery Backup

Very similar to the grid-connected system, this system adds a “battery bank” to collect the power generated from the solar panels. Power stored in the batteries can be used during power outages. The battery bank collects power produced by the solar panels, sends it to the breaker box, and then into the house power system. The components of this type of system consist of:


Solar panels mounted on the roof

An inverter to convert solar electricity from DC energy into AC energy

A battery bank for power storage

A charge controller to prevent overcharging the battery

A junction box that connects the solar panel wiring to the breaker panel on the home

A power meter that displays the amount of power used, produced, and stored in the battery bank

A disconnect switch to prevent islanding during power outages.
