DEYE BOS-A – High Voltage Battery (HV) – LiFePO4 battery HV Pack 7.68 kWh

The Deye BOS-A Pack 7.68 kWh is a high-voltage lithium-iron-phosphate (LiFePO4) battery designed for building scalable energy storage systems. It is part of Deye's BOS-A series and has been developed specifically for commercial and industrial applications as well as large hybrid PV systems.

The battery offers a modular (rack-mounted) design that allows for easy expansion according to system needs. It is possible to connect multiple battery modules in series and parallel, which provides flexibility and high total energy capacity.

With an integrated intelligent BMS system, BOS-A guarantees optimal operation, cell balance and a high level of safety. Supports communication with inverters via CAN interface and allows full control and monitoring of the system.

Thanks to the long service life (over 6000 cycles) and deep discharge capability, this battery is a reliable solution for long-term energy storage.
