Deye GB-LM4.0 battery module high voltage

Modularity and scalability

The Deye GB-L battery bank, an innovative solution for off-grid solar energy storage applications, features a modular design. This allows multiple 4.09 kWh battery modules to be connected in series to achieve system voltages between 204.8V and 614.4V and system capacities from 8.18 kWh to 24.56 kWh. Its adaptability makes it ideal for a wide range of applications, from small remote cabins to microgrids of entire villages.

Focus on security

Safety is paramount with the GB-L solar power battery bank. The battery bank features built-in explosion venting, fire protection to interrupt the ignition source, and a cable-free connection of the high-voltage battery modules in series, increasing reliability. Thermal sensors monitor cell and system temperatures, and an optional heating system enables operation down to -20°C. With an IP65 rating and corrosion protection, the GB-L is ready for challenging environments.

Intelligent energy management

The GB-L battery bank's intelligent system enables remote monitoring and updates, providing real-time data such as the state of charge via the LCD display and to connected devices via CAN bus and RS485. With a depth of discharge of up to 90%, the GB-L offers excellent energy capacity for powering off-grid loads. Backed by a 10-year warranty, the long-life LiFePO4 chemistry delivers up to 70% of its original capacity over 6,000 cycles. Its advanced design ensures a resilient off-grid power supply for demanding renewable energy projects.
