Factory DK-ESS 20.48KWh 15.36KWh 50A 51.2VDC 120-450V with lithium battery energy storage solar system

Short Description:

The analog front-end collection chip U2 is responsible for the voltage of each battery string and controlling the conduction of the charging and discharging MOS tubes. At the same time, the analog front-end collection chip U2 samples the temperature and transmits all sampled and processed data to the MCU chip U1 through IIC. The present invention can effectively store electricity using a lithium battery; And the battery capacity of lithium batteries is optional; Moreover, the manufacturing cost of the lithium Battery management system is low, and multiple lithium battery modules can be monitored separately, so that multiple modules can be automatically identified and stacked.

Product description

The all-new home appliance style energy storage integrated system adopts a stacked design. The system adopts the ALL-IN-ONE design concept and has fully integrated high-performance PCS, BMS, EMS, and battery PACK independently developed. It continues to iterate and innovate in safety performance, application environment, technical parameters, installation convenience, and other aspects, becoming a household smart energy storage system with complete power bands and leading comprehensive performance in the current market.
The stackable household energy storage lithium Battery management system is characterized in that it includes MCU chip U1, analog front-end acquisition chip U2, LCD segment code screen display module, touch button, communication module, address selection module, current limiting module and charge discharge MOS tube; The MCU chip U1 centrally controls the Battery management system and performs resource allocation and data detection; The analog front-end collection chip U2 is responsible for the voltage of each battery string and controlling the conduction of the charging and discharging MOS tubes. At the same time, the analog front-end collection chip U2 samples the temperature and transmits all sampled and processed data to the MCU chip U1 through IIC. The present invention can effectively store electricity using a lithium battery; And the battery capacity of lithium batteries is optional; Moreover, the manufacturing cost of the lithium Battery management system is low, and multiple lithium battery modules can be monitored separately, so that multiple modules can be automatically identified and stacked.

Stack Lithium Battery Energy Storage System

Product features

1. The stacked energy storage system adopts self-developed seamless off grid switching technology, and the off grid switching time is less than 10ms, ensuring the continuous and stable operation of high-precision equipment and avoiding sudden interruptions. Intelligent control of household electricity load, high output power quality, and strong grid friendliness.
2. The stackable energy storage system uses safe and reliable Iron(III) phosphate lithium battery cells, and all battery modules are PACK level fire protection configuration. The independently developed BMS management system has superior performance and can be controlled safely and freely.
3. The stacked energy storage system adopts self-developed seamless off grid switching technology, and the off grid switching time is less than 10ms, ensuring the continuous and stable operation of high-precision equipment and avoiding sudden interruptions. Intelligent control of household electricity load, high output power quality, and strong grid friendliness.
3. Stacked energy storage system, with a total of 8 power bands available for selection, including 5/6/8/10/12/15/17/20, to meet the needs of households with different loads. Flexible combination and expansion of battery capacity make it easier for users to choose energy storage systems.
4. Stacked energy storage system can be used for spontaneous self use of photovoltaic energy during the day, with surplus storage. When the photovoltaic system does not generate electricity, it can be powered by the system to improve the spontaneous self use rate of electricity. At the same time, the system can also be connected to the power grid without photovoltaic connection, participating in power peak shifting and valley filling, ensuring that the equipment is not affected by sudden power outages for normal use.
