Description High Voltage Energy Storage System Deye GB-L Safety Built-in explosion relief device to dredge gas, and built-in fire protection device to cut off the fire source for 3 seconds High voltage stack Modules are connected in series without a cable connection, and a high-voltage platform improves system efficiency Thermal management Temperature detection of key parts, cells, power plug-ins, etc. Wide temperature operation The heating function is optional to meet the application scenarios with low temperatures and no sense Environmental friendliness IP protection grade 65, anti-corrosion grade ≥C2, environmental protection battery Intelligent and visual Support remote upgrade, real-time battery warning information push, LCD data display The Deye GB-L solar power off grid battery bank is an intelligent and safe lithium iron phosphate (LiFePO4) battery system designed for off-grid solar energy storage applications. With a modular design, the GB-L system can be easily scaled up by connecting multiple 4.09 kWh battery modules in series to achieve system voltages from 204.8V up to 614.4V and system capacities from 8.18 kWh up to 24.56 kWh. Safety is a key focus of the GB-L solar power off grid battery bank. It features built-in explosion relief to vent gas and fire protection to cut off the ignition source. The high-voltage battery modules connect in series without cables for increased reliability. Thermal sensors monitor cell and system temperatures, and the optional heating system allows operation down to -20°C. With an IP65 rating and anti-corrosion protection, the GB-L solar power off grid battery bank can withstand challenging environments. The smart GB-L solar power off grid battery bank enables remote monitoring and upgrades. It provides real-time system data like the state of charge on the LCD display and to connected devices via CAN bus and RS485. With a depth of discharge up to 90%, the GB-L provides excellent energy capacity to power off-grid loads. Backed by a 10 year warranty, the long-lasting LiFePO4 chemistry offers over 6000 cycles to 70% of original capacity. With dimensions from 650mm to 1530mm high depending on the number of modules, the floor-mounted GB-L solar power off grid battery bank scales to fit applications from small off-grid cabins to village microgrids. Weighing from 97kg to 253kg, the modular and compact design simplifies transport, installation and maintenance. The advanced Deye GB-L solar power off grid battery bank intelligently stores and supplies solar energy for resilient off-grid power. Its safe, robust and flexible architecture meets the needs of challenging off-grid renewable energy projects.
