BYD Battery Box Premium HVS 7.7

BYD BATTERY-BOX PREMIUM HVS 7.7 high-volt battery

The new system generation is based on the known storage systems and has all previous functions. With the Battery-Box Premium HVS, a battery module with higher storage capacities than its predecessor is launched in the market. Through the further development of cell technology, the system weight could be reduced by almost 30%. The overall depth was also reduced by 8 cm. This means that less floor space is required. At the same time the new devices have a slimmer appearance. One of the highlights: the new storage systems come with “protection class IP55”. This enables the use also in outdoor areas.

More flexibility and scalability. With the new generation, up to three battery towers can now be connected to one system. However, BYD remains true to itself when it comes to charge and discharge power. Each battery can also deliver the nominal capacity as power, i.e. 1C. This makes the new series ideally suited for on-grid, on-grid plus backup and off-grid systems. Since the software remains the same in the new models, the Premium HVS are still compatible with Kostal, SMA, Fronius and GoodWe.
