Powering Tomorrow: Jinko’s BESS Top Solutions
The global shift toward renewable energy has made Energy Storage Systems (ESS) a vital part of the energy landscape. Worldwide, energy storage capacity has grown rapidly, nearly tripling from 35 GWh in 2022 to about 95 GWh in 2023, with forecasts reaching 205 GWh by 2025. This trend is fueled by regional factors, including policy incentives and time-of-use pricing in China, large-scale storage, ancillary services, energy arbitrage, improved network resilience in the USA, high residential electricity prices, and supportive policies in Europe, as well as broad decarbonization initiatives in Australia and the Middle East.
JinkoSolar a JinkoESS
JinkoSolar has consistently held the top position for global PV panel shipments for many consecutive years, having delivered over 320 GW globally and maintaining a 15.5% market share. Their manufacturing prowess is evident across 14 factories spanning China, Malaysia, Vietnam, the USA, and Saudi Arabia.
In accordance with the global shift mentioned above, Jinko ESS officially emerged as a separate entity at the end of 2022, building upon JinkoSolar’s initial foray into the energy storage market in 2019. This dedicated focus has been validated by its recognition as a BloombergNEF Tier 1 energy storage manufacturer since 2024, a status it has maintained for six consecutive quarters, making JinkoSolar a Tier 1 provider for both PV and ESS solutions. Jinko ESS operates with a complete, independent company structure, including dedicated R&D, sales, marketing, finance, and legal departments, ensuring a highly focused approach to energy storage activities.
JinkoSolar’s strategy includes significant vertical integration within the ESS sector, mirroring its success in the PV sector. The company aims to self-manufacture almost all ESS components. By June 2024, they began in-house production of 314 Ah cells, with a 5 GWh cell production line planned for the year. Internally-produced Battery Management Systems (BMS) have been operational since late 2023. While JinkoSolar develops its own Power Conversion Systems (PCS) for certain markets, it also collaborates with established third-party suppliers, such as SMA and Parelectronics, for other regions. Their manufacturing capacity for ESS systems is expanding rapidly, from 4 GWh in late 2023/early 2024 to 17 GWh by the end of 2025, and projected to exceed 37 GWh by Q3 2026, ensuring robust capability to meet diverse project demands.
JinkoSolar champions safe and intelligent energy storage through its proprietary liquid cooling thermal management technology, which addresses common challenges like thermal inefficiency, safety risks, and complex operation and maintenance. This is embodied in their two flagship product lines: the SunGiga series for Commercial and Industrial (C&I) applications and the SunTera series for Utility Scale ESS.
JinkoSolar's SunGiga Series for Commercial & Industrial Applications
The SunGiga series offers advanced C&I energy storage solutions featuring liquid cooling, intelligent monitoring, comprehensive safety systems, and optimised operational performance.
SunGiga G1 (215 kWh): Jinko SUNGIGA 100KW-215 kWh (Liquid Cooling)
This all-in-one system provides a 215 kWh capacity with an integrated 100 kW Power Conversion System (PCS). It operates at altitudes up to 2000m, offers optional C5 corrosion resistance, and features an IP55-rated external enclosure (IP67 for internal batteries). The system is designed to operate in a wide temperature range of -20 to +50°C and uses 280 Ah cells. Comprising five battery packs, it is highly scalable, allowing up to ten units to be connected for a total capacity of 2.15 MWh. Its 400V AC operating voltage ensures compatibility with various European mechanical machinery. Safety features include an aerosol fire suppression system.
SunGiga G2 (261 kWh): This second-generation system, soon to be released, boasts increased energy density due to a larger 314 Ah cell size. All components have been upgraded, extending the operating temperature range to -30 to +55°C and the altitude capacity to 3000m. The PCS power is enhanced to 125 kW, and the cell life is increased. Scalability is also improved, allowing up to twelve units to be connected, and the system features a slightly thinner footprint for better space utilization. A significant upgrade in the G2 models is the blackstart capability for off-grid power, a feature not present in the G1.
SunGiga G2 Plus (520 kWh): This larger system combines two G2 units, offering a total capacity of 520 kWh. It can operate as a 2-hour (0.5 C rate) or 4-hour system (0.25 C rate) and contains ten battery packs. It features an extended 8,000-cycle life. The system integrates an advanced fire suppression design, including an aerosol gas fire extinguishing system, smoke detection, temperature sensors, flammable gas detection, and passive ventilation.
SunGiga systems are versatile and suitable for a wide range of applications, including EV charging stations, backup power, self-consumption optimization, peak value charging, and energy arbitrage. Successful installations demonstrate their utility:
- 09/2024 – Netherlands -Netherlands C&I CSS Project – Capacity: 0.5 MW / 1.075 MWh This system supports self-consumption and peak shaving at a frozen food company
- 04/2024 – Japan – Miyazaki DC-coupled system – Capacity: 7.74 MW / 15.48 MWh DC-coupled PV ESS in mountainous terrain overcomes challenging logistics and allows a 24-hour period where it is possible to sell electricity, maximizing the owner’s profit.
- 08/2023 – China – Lvliang Distributed PV ESS Project – Capacity: 1MW / 2.15 MWh This distributed PV ESS project is dedicated to user-side photovoltaic power generation with energy storage and employs the use of ten G1, all-in-one machines.
JinkoSolar's SunTera Series for Utility-Scale
JinkoSolar has developed a powerful battery solution for large-scale energy projects called the SunTera series. At its core, the system uses reliable LFP battery chemistry packed into a standard 20-foot container, delivering up to 5 MWh of energy.
What makes it stand out is its smart and safe design. The container cleverly separates the batteries from the electrical and fire safety systems to boost performance and prevent issues. It also features an advanced liquid cooling system, which is much more effective and quieter than air cooling. This keeps the batteries at their ideal temperature, helping them last longer and perform better. On the safety front, the SunTera is built to meet tough industry standards, with multiple layers of protection that include advanced detection, fire suppression systems, and a design that prevents heat from spreading.
The environmental adaptability of Jinko’s energy storage systems is a key design feature. Durability is assured through a C5 corrosion rating and IP55 water protection. The validated operational parameters include functionality at altitudes up to 4000m and a wide ambient temperature tolerance from -30°C to 55°C. Acoustically, the systems are engineered for low-noise output (≤ 75dB), ensuring compliance in areas with strict noise regulations.
Looking ahead, JinkoSolar has a clear improvement plan; while today’s models are already very efficient and can last for over 8,000 cycles, they are planning to release new versions soon that will push capacity past 6 MWh and extend the battery lifetime to over 15,000 cycles.
Below are some examples of proven installations:
- 09/2023 – China – Dongguan C&I Projects – Capacity: 73.3 MW / 157.6 MWh
These projects are part of a larger installation with a total capacity of 87 MW / 209 MWh, which also includes a utility portion.
- 04/2024 – Tahiti – Tahiti BESS Project – (considered a European project due to French regulations) – Capacity: 8.6 MW / 17.2 MWh
This large-scale project merges agriculture with renewable energy, specifically involving photovoltaic greenhouses for “100% organic” production across 10 hectares. It is designed to supply 15,000 MWh/year, equivalent to the electricity needs of over 5,000 households.
- 06/2025 – Thailand – Thailand Utility ESS Project – Capacity: 12.5 MW / 25 MWh
This is recognised as JinkoSolar’s flagship utility ESS project and represents their first utility deployment in Thailand. It is a solar-integrated system featuring Jinko’s Suntera G2 5 MWh product and 2.5 MW PCS MV Skids. This project is strategically positioned within Southeast Asia’s high-growth renewable energy market and aims to demonstrate Jinko’s capability to deliver complex grid solutions and accelerate Thailand’s clean energy adoption.
