Product Description

Customized 80kwh 100kwh ESS Energy Storage System High Voltage LiFePO4 Lithium Ion Battery built in MPPT Solar Controller

ESS introduction:

ESS energy storage lithium battery system is composed of high quality lithium iron phosphate core (series-parallel connection) and advanced BMS management system. It adopts master-slave mode, which is convenient for monitoring and controlling the input and output system. The charging and discharging are independent, it can control the charging current of the AC charger and solar controller according to the battery temperature, voltage and SOC to better protect the battery cells from overcharging, overheating and discharging. It has high reliability and long life, products developed for applications such as solar energy storage, industrial and commercial energy storage, household energy storage, charging piles, data room and other applications.

ESS Advantages:

• All-in-one design, high integration and space saving installation
• Using high-performance lithium iron phosphate cells, laser welding, good cell consistency, designed service life of more than 10 years
• Charging and discharging are controlled separately, which is convenient and reliable to control charging and discharging. The discharge port will not be disconnected when over-charging, and the charging port will not be disconnected when over-discharging, the system has good stability
• Master-slave mode, passive equalization, can manage the equalization resistance, can set the equalization start voltage difference, and monitor the equalization resistance temperature, more intelligent and safe, and reduce the impact of barrel effect on system energy storage
• BMS adopts NXP(USA) automotive-grade high-performance chips, with strong anti-interference, good reliability and wide temperature range
• CAN2 communication interface, has the advantages of strong real-time performance, long transmission distance, strong anti-electromagnetic interference ability
• System parameters can be set through the host computer, such as fan start and stop temperature, charger maximum current setting, charge and discharge current correction, SOC correction, with insulation leakage detection function to prevent oil leakage and short circuit of the cell
• Integrated solar controller, AC charger, BMS communication control, more safe and reliable
• Cell temperature management, can be automatically controlled with the air conditioner heater according to the cell condition to make the cell works at the most suitable temperature, and can be linked with the fire protection system as needed
• 5 inch LCD screen display, easy to operate, can check the temperature, voltage, working status, discharge current, dynamic and static SOC algorithm of a single cell, local display of alarm info, alarm level distinction, accurate positioning of abnormal cells
  
• Certified by UL1741 and CSA22.2
