Deye GB-L Pro Pack \u2013 high-voltage LiFePO4 energy storage module for residential solar systems<\/h2>\n

The Deye GB-L Pro Pack<\/strong> is a 4.09 kWh capacity, high-voltage LiFePO4 energy storage module<\/strong> 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 \u2013 making the Deye GB-L Pro Pack<\/strong> flexibly scalable to your household’s energy needs, from solar energy storage to increasing self-consumption and providing reliable home backup power. <\/p>\n

Why choose the Deye GB-L Pro Pack energy storage?<\/h3>\n

The Deye GB-L Pro Pack battery<\/strong> 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. <\/p>\n

Key advantages of the Deye GB-L Pro Pack<\/h3>\n
    \n
  • Uncompromising safety<\/strong> \u2013 built-in aerosol fire suppression and gas detection system, overpressure relief valve, and fire protection disconnect<\/li>\n
  • Cable-free, fast installation<\/strong> \u2013 modules simply snap together, no error-prone cabling between modules<\/li>\n
  • Intelligent thermal management<\/strong> \u2013 temperature monitoring of critical components, cells and connectors, with optional heating function for low-temperature operation<\/li>\n
  • Outdoor tolerance<\/strong> \u2013 IP65 protection and C2 corrosion resistance for dusty, humid environments<\/li>\n
  • Smart and transparent monitoring<\/strong> \u2013 LCD display, real-time alerts, remote firmware updates<\/li>\n
  • Flexible expandability<\/strong> \u2013 up to 6 modules can be stacked in series under a single BMS, up to approx. 24.5 kWh <\/li>\n
  • Long service life and reliable support<\/strong> \u2013 \u22656000 cycles and 10-year warranty<\/li>\n<\/ul>\n

    Applications<\/h3>\n

    The Deye GB-L Pro Pack energy storage<\/strong> is ideal for storing solar energy generated during the day for use in the evening or during cloudy weather \u2013 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). <\/p>\n
