The GB-L-Pro is a high-voltage stacked residential battery system built from LiFePO4 4 kWh modules. Each module (GB-L-Pro-Pack4.1-2) is 102.4 V / 40 Ah / 4 kWh, and the system stacks 2–6 modules for 8 / 12 / 16 / 20 / 24 kWh. It is used as a connected battery for intermediate storage of excess PV energy in an inverter system.
The system consists of the battery module (GB-L-Pro-Pack4.1-2), the high-voltage control box (GB-LBS-Pro), and the battery base (GB-L Base). Modules are stacked on the base and managed by the control box.
Each module is 4 kWh. You can connect 2 to 6 modules in series for 8 / 12 / 16 / 20 / 24 kWh (system nominal voltage 204.8–614.4 V).
Module Nominal Voltage: 102.4 V, Capacity 40 Ah, Energy 4 kWh. Charge/Discharge Current: 40 A nominal / 50 A max (peak discharge 50 A for 2 minutes at 25°C).
Chemistry is LiFePO4 (LFP) with a cycle life of 6000 (25±2°C, 0.5C/0.5C, to 70% EOL).
Communication ports are CAN2.0 and RS485. An LCD displays SOC, Power and Total Voltage.
Charge and discharge: -20~55°C; storage: 0~35°C. Humidity 5%~90%, altitude up to 2000 m.
Ingress Protection is IP65 and installation is floor-mounted. Install in a dry, well-ventilated place away from flammable, explosive or corrosive materials.
The GB-L-Pro is a connected battery for intermediate storage of excess PV energy in an inverter system. Please confirm compatibility (voltage and communication) with your inverter and installer before connection.
Certifications: CE / IEC62619 / VDE 2510-50 / UN38.3.
