Solar Energy Storage System (BESS): Technology, Design & Applications

A solar revolution is taking hold. It is not some distant dream that one day solar energy will play significant role, it’s current reality. And at very center of that revolution is energy storage system. Although plentiful, solar energy isn’t always available when it’s needed. You need something to hold onto that precious power when sun is high so you can use it when it goes down, or during those cloudy periods that hit just when coffee maker is being switched on and your computer whirs into action. This is where Battery Energy Storage System (BESS) comes in.

JOZOKING (TIANJIN) TECHNOLOGY CO., LTD has invested years of R&D in traditional lead acid battery bank as well as cutting edge battery technology so that we can provide total solution to solar energy storage system with products range from old traditional battery technologies to newest Lithium chemistries to most established markets in Europe, North America and Australia. In this article, we take you on deeper journey through technology behind, design, real-world use of modern solar energy storage systems, and show how new technology on JOZOKING AGM battery, GEL battery, NCM battery and LFP battery, is allowing houses, business and industries to achieve genuine energy autonomy.

Choosing the Right Chemistry: Lead-Acid vs. Lithium-Ion

At heart of any solar battery system is its battery chemistry and selecting between lead-acid and lithium-ion brings significant differences in terms of efficiency, cost, and lifespan. With expertise across both families, JOZOKING is actually able to meet every requirement for this application.

Lead-Acid Batteries: Proven and Reliable

JOZOKING's lead acid battery lineup comes in two premium designs - AGM and GEL. Lead-acid batteries manufactured using JOZOKING's innovative NCMA+Si negative electrodes increases battery's energy density and decreases it's internal impedance making unit perform brilliantly where high peak current burst is needed like start up of an engine, or sudden battery backup power .JOZOKING's GEL lead acid battery uses an advanced silicon-based electrolyte for increased electrolyte gel strength, minimized acid stratification and eliminates acid drying to maintain performance over many deep cycle charges (hundreds of charge/discharge cycles), perfect for use with stand alone solar panels & battery storage or off grid solar energy solutions, which are normally on daily cycling list.

Lithium-Ion: High Energy Density and Extended Lifespan

When performance is of higher priority, lithium ion solar battery technology is logical choice. JOZOKING produces two main types of lithium chemistry, NCM (Nickel-Cobalt-Manganese) and LFP (Lithium Iron Phosphate). NCM provides very high energy density, often greater than 200Wh/kg, which means you can store lot of energy in small footprint, essential for residential installs where space may be tight. LFP is highly respected for its thermal safety and cycle life, LFP cells can easily achieve >4,000 cycles at 80% depth of discharge, which is more than 10 years of every day usage at very low lifetime cost. Both NCM and LFP are matched with high performance BMS that monitors every individual cells voltage, temperature and SOC for optimal use and safety.

The JOZOKING Difference: Quality, Customization, and Global Support

Our ability to offer quality, flexibility and to enter into long-term partnership with our customer clearly sets JOZOKING apart from rest in solar energy storage market.

Rigorous Quality Assurance Across the Board

Every battery comes off our Tianjin facility perfectly tested-whether from cell sorting and matching, to final performance test of battery pack system. Automated assembly lines keep our units at consistent quality, while in-house R&D teams work endlessly on optimization of electrode formulations, electrolytes, packaging structures to extend capacity and cycle-life further and further. We comply with international CE, UL, UN38.3 standards, and conduct over range of accelerated aging tests, thermal shock cycles and vibrations to ensure reliable performance in operation. The commitment to quality makes our battery trusted by customers in over 60 countries worldwide.

Unmatched Customization Capabilities

We know that every installation is different, which is why we give our clients wide latitude in designing their products. We allow clients to customize battery capacity, voltages, form factors, terminal types, communication methods (CAN, RS485, Modbus), and can adapt products to meet their particular monitoring and inverter systems. For our OEM partners, we invent custom cell chemistries and pack architectures that accommodate special application requirements-such as sub-zero operating temperature performance for Northern Europe, or very high C-rate discharge performance for UPS solutions. Our engineers partner closely with all clients to achieve flawless initial integration and peak system performance.

Global Service Network and Technical Support

Global network JOZOKING offers global support with its sales presence on four continents – North America, Europe, Australia and more, complemented by local support and local warehouses in order to provide rapid response and minimum downtime. Because we work with local distributors and certified installers, no matter whether you’re located in Germany, California or in Queensland area of Australia, you’ll have support on site for expert installation advice and original parts. We train installation teams from basic size calculations, wiring and simple system configuration to complex BMS configuration and remote monitoring.

Innovation for a Sustainable Future

With world increasingly driving towards renewable future, intelligent energy storage will play an even more critical part. We are devoted to pushing battery technology to limit, investigating next-generation materials, building intelligent grid connectivity, and finding innovative second-life use applications for end-of-life EV batteries. Leveraging over hundred years of manufacturing experience and spirit of continuous innovation, we enable individuals and organizations globally to benefit from complete power of sun, one dependable battery at a time.

If you are an industrial plant owner who needs to prevent business disruptions through more reliable, off-grid or stand-alone solar panel and battery storage, we have most cutting-edge technologies and rich portfolio that delivers value for your needs.
