JinkoSolar ESS: Efficient, safe and flexible energy storage system

Recently, JinkoSolar Holding. one of the largest and most innovative solar module manufacturers in the world, announced the completion of an order for its Energy Storage System (ESS) with one of the largest distributors in Africa.

The distributor has contracted with JinkoSolar for PV modules and by signing the JinkoSolar ESS order, the client has demonstrated recognition and trust in this new product and brand.

JinkoSolar Energy Storage System is a brand new product of the company’s “PV + ESS” business segment. The product can be paired with PV modules to improve the use of new energy and solve the problem of electricity demand in areas with inadequate power systems. JinkoSolar can provide the most appropriate clean energy solutions for large power plant projects connected to the grid, commercial and industrial power demand, or residential off-grid power demand.

With rapid economic growth, the electricity demand in Africa is expected to double by 2030. As more African countries and energy companies promote the development of new energy capacity, this generation will bring new development opportunities to Africa.

Unpacking the residential energy storage system

JinkoSolar offers different Energy Storage System solutions for different application scenarios, helping to improve the power supply structure in Africa. For some areas with limited access to the grid, JinkoSolar Residential Energy Storage System can effectively solve the problem of local power shortage with high performance and high-security features.

JinkoSolar Residential Energy Storage System ensures excellent product safety while maintaining high performance. It uses a lithium iron phosphate pouch battery with the advantages of high energy density, reliable safety, low inner resistance and flexible design. The energy density of the pouch battery is basically 10 to 15% higher than a prismatic cell, which can effectively improve the performance and efficiency of the system.

Within the same material system, the pouch battery is sealed in aluminium plastic film. Once the battery thermal runaway happens, the heat will be released by gas venting smoothly; while prismatic batteries are packed in a hard shell, heat cannot be released. Meanwhile, internal pressure is large, which means it may cause an explosion. In addition, since the internal resistance of the battery is low, it can significantly reduce the battery self-discharge, improve battery rate performance, cycle life, and ensure less heat production.

The overall flexibility is also a key feature of JinkoSolar Residential Energy Storage System. The PCS module of the system has a comprehensive range of specifications, can provide four kinds of PCS of 3.6kW, 5kW, 8kW and 10kW for customers to choose from, so as to meet the requirements of product specifications in different application scenarios.

The battery cabinet of the Energy Storage System supports parallel and series connection, which can realise parallel capacity expansion through high-voltage wiring harness connected in parallel/series, quickly improve power consumption and meet differentiated electricity demand. Beyond that, JinkoSolar Residential Energy Storage System supports on- and off-grid switching function. In relatively developed areas of Africa, the system can also be integrated into the grid to maximise IRR and lower LCOE.

As the world’s leading PV company, JinkoSolar is committed to providing global customers with a more comprehensive range of new energy solutions by expanding its “PV +” business segment. As an important product in the “PV + ESS” business segment, JinkoSolar Energy Storage System will achieve better electricity management for customers in Africa and around the world.
