SMA SBS-ABU-200-US-10 Sunny Boy Storage Automatic Back-up

Manufacturer Part: SBS-ABU-200-US-10

200A SMA SBS Automatic Backup Unit. Includes Wattnode Energy Meter and (2) CTs.

SMA's robust and versatile automatic backup unit. Enclosure includes an automatic transfer switch designed specifically for use with the SMA Sunny Boy Storage inverter family. In the event of a grid failure, the automatic transfer switch disconnects the PV system, loads and the Sunny Boy Storage from the utility grid and creates a battery-backup grid. The included Backup Unit Controller coordinates grid disconnection and reconnection to ensure minimal downtime while also allowing for up to 5 kVA of unbalanced loads. When paired with SMA Sunny Boy inverters, the Sunny Boy Storage curtails PV power production to match load in the event the battery is full to maximize use of solar production.

While alternative backup systems offer merely a transfer switch and require additional hardware purchases, the new SMA Automatic Backup Unit (ABU) is a truly 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 autotransformer 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 micro grid by monitoring solar generation, load consumption, and battery state-of-charge
