Recently, JinkoSolar and Jinko ESS jointly unveiled a full-scenario PV plus energy storage solution tailored for Artificial Intelligence Data Centers (AIDC) during the 14th Energy Storage International Conference and Expo. Built upon two core product matrices–SunTera energy storage system and AIDC-dedicated PV modules–this green energy solution deeply integrates“ESS + PV”to address key operational challenges in AIDC, including response speed, reliability, safety, cost efficiency, and space utilization, providing a highly suitable, safe, and efficient green energy foundation for global AI infrastructure across all scenarios.
SunTera ESS: Five Core Performance Features Address AIDC's Stringent Operating Conditions
Targeting the unique power demands of AIDC, such as high-frequency pulse loads, millisecond-level fluctuations, high availability, and safety, Jinko ESS leverages its SunTera technology platform to build a full-stack solution covering both AC-side energy storage and DC-side coordination. With five core strengths – millisecond response, high reliability, five-layer safety, 10,000-cycle lifespan, and high-density integration, the system is tailored to AI computing power consumption characteristics.
Millisecond response to smooth load surges: Equipped with grid-forming PCS, the voltage-source response time is ≤10 ms, supporting virtual synchronous generator control and enabling autonomous voltage and frequency reference formation in microgrid scenarios. For overseas AIDC adopting the “HVDC + supercapacitor + BBU” architecture, Jinko ESS’s DC-side products can coordinate with supercapacitors – the supercapacitors handle sub-millisecond pulses while the ESS provides sustained support beyond seconds, effectively protecting electrical equipment from instantaneous high-current impacts.
High reliability ensuring full-lifecycle availability: Modular redundancy design supports N+1 power module configuration; in case of a single-module fault, the system automatically bypasses it. Through BMS and EMS coordination, the system monitors cell parameters in real time and applies machine learning to predict failure risks, triggering maintenance alerts in advance. Under extreme conditions, the ESS supports full-site black start, acting as the master power source in a microgrid to self-start and establish the grid when utility power is lost and gas turbines have not yet started.
Five-layer safety protection for site-level security: A five-layer safety architecture is implemented from cell level, module level, rack level, system level to O&M level. The cells use lithium iron phosphate chemistry with thermal runaway triggering temperature ≥150°C; modules are equipped with aerogel insulation layers; each rack has an independent fire suppression unit. The entire cabinet achieves IP55 protection and C5 anti-corrosion grade, supports remote inspection and OTA upgrades, and has passed large-scale fire testing in accordance with UL 9540A 2026 edition, with safety performance authoritatively validated.
10,000-cycle lifespan adapting to high-frequency dispatch: Powered by Jinko’s self-developed 587Ah/588Ah large-capacity cells, the system delivers over 10,000 cycles and energy efficiency above 95%, reducing lifecycle levelized cost while improving system reliability.
High energy density saving valuable footprint: Single-cabinet capacity ranges from 3.44MWh to 6.9MWh, with energy density more than 15% higher than the industry average, effectively saving valuable distribution space within AIDC campuses. Full factory prefabrication and on-site foundation-only installation significantly shorten AIDC project construction cycles.
In addition, the SunTera platform enables differentiated technical adaptations for AIDC construction paths in different regions. In the North American market, it supports stable operation under low SCR (short-circuit ratio ≤1.1), features high/low voltage ride-through capability, can form a self-built microgrid with gas turbines, and provides black start support to address the 5-7 year utility grid expansion cycles. In the Chinese market, diversified revenue models such as peak shaving, demand management, and ancillary services help operators reduce electricity costs while meeting policy requirements for over 80% green power consumption. The 25MW/200MWh project at China Telecom's Anhui Intelligent Computing Center has validated the long-term economic viability of energy storage in data center scenarios.
AIDC-Dedicated PV Modules: Six Core Advantages Define New Standards for the Computing Era
Addressing the special needs of AIDC–high loads, 24/7 operation, extreme weather resistance, and high safety–JinkoSolar's data-center-dedicated PV modules, built on the Tiger Neo 3.0, deliver six core strengths: high efficiency, high bifaciality, excellent low-irradiance response, high fire resistance, hail resistance, and high mechanical load.
High efficiency and high power: Front-side efficiency ≥24.8%, power ≥670W, minimizing lifecycle LCOE and generating more green electricity per unit footprint, injecting stronger clean energy into computing hubs at the source.
High bifaciality: Bifacial ratio reaches 85±5%. Taking a 670W module with 90% bifaciality as an example, under 0.288 ground albedo, the equivalent total output power can reach 844W–for every 1W of front-side power cost paid, users effectively obtain 1.26W of combined generation capacity, delivering“free capacity expansion”benefits for AI data centers.
Excellent low-irradiance response: In the 100-200W/m² low-irradiance range, power generation during morning and evening hours is up to 8.93% higher than BC modules. In extreme low-light conditions such as heavy fog or building shading, relative power output remains at 95%-98%. The generation curve better matches the long-duration, 24/7, stable power demand of data centers. In regions with significant peak-valley price differences, this further improves project returns while reducing grid pressure.
High fire resistance and flame retardancy: The modules have passed the most stringent IEC 61730-2:2023 standard in PV industry, and are the first in China to achieve both IEC Class A and UL 790 Type A certifications–representing the highest level of fire performance in the PV industry. Key insulating materials meet UL 94 V-0, the highest flame retardancy rating, with self-extinguishing within 10 seconds after the flame is removed, reducing DC arcing risks at the source.
Superior hail resistance: Successfully passed the 55mm diameter hail impact test (close to tennis ball size), far exceeding the standard 25mm requirement, effectively breaking the risk transmission chain of “mechanical damage → electrical failure → fire hazard”.
Ultra-high mechanical load: Passed 6000Pa front-side load and 4000Pa back-side load tests, capable of withstanding over 600kg of snow pressure per square meter, ensuring structural integrity and electrical safety under extreme weather conditions.
The Jinko AIDC full-scenario PV+ESS solution achieves deep integration of solar and storage, addressing key AIDC needs including power supply challenges driven by computing demand, safe and reliable operation, and cost efficiency. With a scenario-oriented design approach, it provides a highly adaptable green energy solution for AIDC applications. As global AI infrastructure continues to expand, Jinko ESS will deliver stable and reliable energy foundations for intelligent computing centers, supporting the green transformation of the computing era.
