SUITABLE FOR ANY INITIAL SITUATION
NEW INSTALLATION OR RETROFIT: PV SYSTEM WITH BATTERY STORAGE
A PV system with a storage system makes the user independent from conventional power generators and rising electricity costs. With the Sunny Boy Storage, this is particularly easy and quick. Whether a new set-up or an existing system, the Sunny Boy Storage can be retrofitted in any existing PV system.
SAFE: SUPPLY GUARANTEED EVEN DURING POWER OUTAGES
PV system operators always have a reliable supply during power outages. In the event of grid failure, the inverter can be manually switched to the emergency power supply with the integrated Secure Power Supply function. Secure Power Supply supplies a line conductor with nominal device power of up to 3.7 kW from the battery. The optional transfer switch can even take over the household’s entire electricity supply of all three line conductors, fully automatically, in the event of grid failure. This means that you will have a reliable energy supply any time of the day and night.
EXPAND: ADAPT AN EXISTING BATTERY STORAGE SYSTEM TO INCREASING DEMAND
For the first time, the multistring battery inverter offers the option to connect up to three high-voltage batteries made by different manufacturers. The system can therefore be expanded in the future due to rising energy demand without any problems. To connect larger batteries, three separate battery inputs can also be connected in parallel.
Compatibility of Sunny Boy Storage 3.7 / 5.0 / 6.0 multistring battery inverters and the BYD Battery Box Premium (series HVS / HVM) was officially released by both parties in 2020-CW37.
