Deye GB-LB BMS Control Box and Base for High-Voltage All-in-One Systems 120-750 V
The Deye GB-LB is the control box carrying the cluster BMS of the GB-L high-voltage storage systems, supplied together with the base the battery module stack sits on. It supervises voltages, currents and temperatures of the whole string, integrates DC isolation and talks to the hybrid inverter over CAN 2.0 and RS485.
It works with the GB-LM4.0 modules of 4.09 kWh at 102.4 V: 2 to 6 modules in series, meaning systems from 8.18 to 24.56 kWh, with an operating window of 120 to 750 Vdc. The IP65 enclosure allows installation in unconditioned rooms too, making it the part you need to complete a GB-L battery paired with Deye high-voltage inverters.
Key features
Integrated cluster BMSMonitors voltages, currents and temperatures of every module and safely handles DC isolation of the string.
120-750 Vdc windowCovers the full scalability of the GB-L series, from 2 up to 6 battery modules in series.
IP65 enclosureHigh ingress protection and operation from -20 to 65 °C, harsh environments included.
Base includedThe kit comes with the base that supports and aligns the module stack, ready for floor mounting.
