Deye GB-LB BMS Control Box and Base for All-in-One High Voltage Systems 120-750 V
The Deye GB-LBS-PRO is the high voltage control box (cluster BMS) of the Deye GB-L PRO series residential storage systems, supplied here together with the GB-LBase support base on which the battery modules are stacked. The box manages charging and discharging of the whole stack, balances the cells, monitors the temperature of critical points and provides the electrical and communication link between the battery pack and the hybrid inverter.
It is floor mounted: the GB-LBase base is laid down first and the GB-L Pro modules (4 kWh / 4.1 kWh each) are fitted in series on top of it, connecting without any cabling between one module and the next. The unit works within a voltage range of 120-750 V DC, with a rated charge and discharge current of 40 A and a 50 A peak, and it is compatible with Deye high voltage hybrid inverters in the all-in-one solutions.
Key features
Cluster BMS ControlIt manages charging, discharging and cell balancing across the whole stack, optimizing energy flow and battery life.
Wide Voltage RangeIt operates from 120 to 750 V DC; the high voltage architecture reduces losses and improves system efficiency.
Base IncludedThe item also includes the GB-LBase base (540 × 385 × 100 mm, 7 kg) that provides mechanical support for the stacked modules.
Cable-Free StackingThe battery modules connect in series by direct contact, cutting installation time and wiring errors.
Thermal Management and SafetyTemperature sensing on critical components and protections against over-temperature and overcurrent.
IP65 Protection RatingAn enclosure suitable for residential installations even in harsh environments, with an operating range from -20 to 65 °C.
