BYD Battery-Box Premium HVS 12.8 is high-voltage storage battery for all applications suitable for 1 and 3 phase systems with flexible modular system and parallel connection.

The new BYD Battery-Box Premium HVS 12.8 battery storage system generation builds on the well-known memories and has all previous functions. The Battery-Box Premium HVS is a battery module that has higher storage capacities than its predecessor. The further development of cell technology has reduced the system weight by almost 30%. The construction depth was also reduced by 8 cm. This means that less floor space is required. At the same time, the new devices have a leaner look. One of the highlights: The new storage systems have “protection class IP55”. This enables use outside as well.

BYD Premium HVS are compatible with Kostal Plenticore Plus, Sungrow Hybrid as well as Kostal PIKO MP plus and GoodWe Hybrid Inverters.
