High Voltage DKHR-RACK: Quality Factory-made Products

DKHR-RACK-series battery products are high-voltage and large-capacity systems developed for industrial andcommercial emergency power supply, peak shaving and valley filling, and power supply in remote mountainous areas, islands and other areas without electricity and weak electric Using lithium iron phosphate cells and configuring a customized BMS system to effectively manage the cells, compared with traditional batteries, it has much more better product performance and safety and reliability. Diversified communication interfaces and software protoco libraries enable the battery system to communicate directly with all mainstream inverters on the market. The product has many charge and discharge cycles, high power density and long service life. Unique design and innovation have been carried out in compatibility, energy density, dynamic monitoring,safety, reliability and product appearance, whichcan bring users a better energy storage application experience. ● Long Cycle Life: 10 times longer cycle life time than lead acid battery. ● Higher Energy density: the energy density of lithium battery pack is 110wh-150wh/kg, and the lead acid is 40wh-70wh/kg, so the weight of lithium battery is only 1/2-1/3 of lead acid battery if the same energy. ● Higher Power Rate: 0.5c-1c continues discharge rate and 2c-5c peak discharge rate, give much more powerful output current. ● Wider Temperature Range: -20℃~60℃ ● Superior Safety: Use more safer lifepo4 cells, and higher quality BMS, make full protection of the battery pack. Overvoltage protection Overcurrent protection Short circuit protection Overcharge protection Over discharge protection Reverse connection protection Overheating protection Overload protection
