This Sunny Boy is discontinued and is replaced by SMA's Sunny Boy Smart Energy Series.
The Sunny Boy Storage is the newest addition to the SMA product line. The Sunny Boy Storage is specifically designed for energy management services such as; zero export and peak load shaving. The Sunny Storage AC coupled architecture allows for easy integration with existing PV systems as well as new installations of on-grid residential systems up to 30kWp. Equipped with the Secure Power Supply (SPS), up to 2000 W at 120 VAC of convenience power can be supplied through a dedicated protected outlet both day and night as long as battery power is available.
The inverter is available in a variety of sizes with up to three 10 A DC battery inputs allowing for extensive system flexibility. Each battery input has a voltage range of 100 V DC to 500 V DC and can support different battery brands and capacities on the same inverter.
The Sunny Boy Storage can be accessed via smart phone or laptop through WLAN connection for speedy configuration to decrease installation time. Communication is simplified with a direct Ethernet or Wi-Fi connection to SunnyPortal/SunnyPlaces via Webconnect.
The new SMA Automatic Backup Unit (SBS-ABU-200-US-10) allows the Sunny Boy Storage inverters to be used as a home backup system in event of grid outage or disruption, and is designed to specifically communicate with the SMA Sunny Boy line of inverters. This unit includes an automatic transfer switch that disconnects the PV System and loads from the utility grid, and creates a small 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.
