SMA Sunny Boy 3,7 kW – 400 V AC-coupled energy storage inverter – single phase
With the SUNNY BOY STORAGE multistring battery inverter, up to three different high-voltage batteries can be connected to one battery inverter for the first time. Three DC inputs can also be connected in parallel to connect larger batteries . The Sunny Boy Storage has an integrated emergency power supply that can be switched manually. In addition, it can even take over the entire power supply of the three external conductors via the optional automatic transfer unit. Thanks to proven AC coupling, the Sunny Boy Storage is ideally suited for new and retrofit systems. The integrated web server enables quick and easy commissioning, which is also possible via smartphone or laptop. Thanks to the direct connection to Sunny Portal and Sunny Places, the energy flows in the household are completely transparent.
NEW INSTALLATION OR RETROFIT: PV SYSTEM WITH BATTERY STORAGE A PV system with a storage system makes the user independent of conventional power generators and rising electricity costs. With the Sunny Boy Storage, this is particularly easy and fast. Whether new or existing system, the Sunny Boy Storage can be retrofitted into any existing PV system. SAFE: SUPPLY GUARANTEED EVEN IN THE EVENT OF A POWER FAILURE PV system operators are always reliably supplied even in the event of power failures. In the event of a power failure, the inverter can be manually switched to emergency power supply with the integrated Secure Power Supply function. Secure Power Supply supplies an external conductor with a device output of up to 3.7 kW from the battery. In the event of a power failure, the optional mains switch can even take over the entire power supply of the household fully automatically via all three external conductors. So you have a reliable energy supply at any time of the day or night. EXPAND: ADAPT AN EXISTING BATTERY STORAGE SYSTEM TO INCREASING DEMAND For the first time, the multistring battery inverter offers the possibility of connecting up to three high-voltage batteries from different manufacturers. The system can therefore also be easily expanded in the future due to the increasing energy demand. To connect larger batteries, three separate battery inputs can also be connected in parallel .
