This AC-Coupled backup power kit is designed to add battery backup to an existing grid-tied system, providing clean and reliable power during an outage. The Outback Radian inverter can couple to most grid-tied inverters rated up to 12kW in size (10kW for Fronius inverters.)
In the event of a power outage, the inverter will automatically turn on to power your essential appliances, and the batteries can be recharged by an existing grid-tied PV system. The batteries can also charge from the power grid when available or a gas generator with the addition of the Generator Protection Kit (see related items.)
