Deye GB-L Pro Pack – high-voltage LiFePO4 energy storage module for residential solar systems
The Deye GB-L Pro Pack is a 4.09 kWh capacity, high-voltage LiFePO4 energy storage module designed for residential solar systems. The modules can be stacked in series without cables using simple plug-in connectors, up to 6 modules under a single BMS – making the Deye GB-L Pro Pack flexibly scalable to your household’s energy needs, from solar energy storage to increasing self-consumption and providing reliable home backup power.
Why choose the Deye GB-L Pro Pack energy storage?
The Deye GB-L Pro Pack battery is based on the safest, proven LiFePO4 (lithium iron phosphate) cell chemistry and is designed for more than 6000 charge cycles. The high-voltage, series configuration increases system efficiency, while cable-free connection makes installation fast and safe. The module operates in full compatibility with all Deye high-voltage inverters from 4 kW to 50 kW, and is capable of utilizing the inverter’s full power in off-grid mode (disconnected from the grid) without additional equipment.
Key advantages of the Deye GB-L Pro Pack
- Uncompromising safety – built-in aerosol fire suppression and gas detection system, overpressure relief valve, and fire protection disconnect
- Cable-free, fast installation – modules simply snap together, no error-prone cabling between modules
- Intelligent thermal management – temperature monitoring of critical components, cells and connectors, with optional heating function for low-temperature operation
- Outdoor tolerance – IP65 protection and C2 corrosion resistance for dusty, humid environments
- Smart and transparent monitoring – LCD display, real-time alerts, remote firmware updates
- Flexible expandability – up to 6 modules can be stacked in series under a single BMS, up to approx. 24.5 kWh
- Long service life and reliable support – ≥6000 cycles and 10-year warranty
Applications
The Deye GB-L Pro Pack energy storage is ideal for storing solar energy generated during the day for use in the evening or during cloudy weather – reducing the amount of expensive electricity purchased from the grid. In case of power outage, when paired with a compatible inverter, it functions as a backup power source, and with variable tariff contracts it enables charging during off-peak periods and discharging during peak hours (load shifting).
