SMA Sunny Boy Storage Auto Backup Unit

The Sunny Boy Storage Automatic Backup Unit (SBS-ABU-200-US-10) is a fully integrated solution for whole home backup power. The ABU consists of several components. The first is a 200 Amp rated contactor, which automatically disconnects the home energy system from grid power during a power outage. The integrated auto-transformer balances up to 5 kVA of imbalance across phases, reducing the potential for system interruption during backup mode operation due to imbalanced loads within the home. The solution also includes built-in energy consumption metering with pre-installed current transformers, eliminating the need for additional hardware and labor. Two 50 Amp breakers are included for landing PV and energy storage inverter output, which also reduces hardware needs. Finally, the ABU features an SMA backup controller, which manages and stabilizes the microgrid by monitoring solar generation, load consumption, and battery state-of-charge.
