On June 11, Kehua, a leading provider of intelligent energy solutions, made a grand appearance at SNEC PV+ 2025, showcasing its new-generation 2,000V 450kW string inverter along with three innovative solutions tailored for large-scale photovoltaic (PV) power plants, generation-side energy storage, and industrial-commercial PV-storage-charging systems. This comprehensive display highlights Kehua’s robust capabilities in driving cost reduction and efficiency enhancement within the industry, as well as its contributions to constructing a new power system.
Kehua has introduced its new-generation utility-scale 2000V 450kW string inverter, marking a pivotal step forward in assisting the industry in achieving cost reduction and efficiency enhancement. This product delivers exceptional value to users in terms of efficient power generation, safety and reliability, intelligent operation and maintenance, and grid-friendliness. Empowered by Kehua’s AI technology, the inverter has achieved qualitative leaps in intelligence, efficiency, and reliability, making PV power plants “smarter.” Through AI, the new-generation utility-scale string inverter optimizes MPPT, enables proactive fault prediction, and manages health, further improving system efficiency and operational safety. Additionally, with AI-enhanced weak grid adaptability, the inverter employs big data to train optimal control algorithms, ensuring continuous grid-connected power generation and enhancing power quality under weak grid conditions.
As a leader in the PV-storage sector, Kehua’s products and solutions cover all application scenarios. In addition to the new product launch, the company also showcased three solutions for large-scale PV power plants, generation-side energy storage, and industrial-commercial PV-storage-charging systems at the exhibition.
Kehua’s new energy generation-side PV solution is characterized by efficient power generation, stability, reliability, and cost savings. It can be flexibly configured according to different terrains and environmental conditions to achieve optimal levelized cost of electricity (LCOE) throughout the system’s lifecycle. In the new energy generation-side PV solution exhibition area, Kehua displayed core products such as the 5MW liquid-cooled centralized inverter-booster integrated machine, 2.5MW liquid-cooled centralized PV inverter, and 320kW string inverter.
Among them, the 5MW liquid-cooled centralized inverter-booster integrated machine is specifically designed for large-scale PV bases in “deserts, gobi, and barren lands,” featuring high power generation, reliability, safety, and protection. It reduces the number of 100MW power station subarrays by 35%, significantly lowering construction and operation and maintenance (O&M) costs. Employing wind-liquid intelligent cooling technology, it can operate at full load even at 45℃. Supporting 1600V open-circuit voltage, it allows for two more modules per string, reducing system costs by 2 cents/W and improving efficiency by 0.15%. High MPPT voltage increases power generation by 0.4%, achieving a dual leap in cost reduction and efficiency enhancement. Multiple protections, such as DC-side intelligent disconnection, terminal temperature detection, and air duct self-cleaning, ensure high safety and low O&M investment.
Currently, Kehua’s new energy generation-side PV solution boasts rich application cases in high-cold, high-altitude, desert-gobi-barren land, hilly-beach-marsh, and various PV+ scenarios.
The exhibition area also highlighted core products such as the 5MW grid-forming centralized energy storage converter-booster integrated machine, 5MW centralized energy storage converter-booster integrated machine, S³-EStation 5MWh liquid-cooled energy storage battery system, 2.5MW liquid-cooled centralized energy storage converter, and 1.25MW centralized energy storage converter. The most eye-catching among them is the new-generation 460kW liquid-cooled cluster-level management PCS launched in April 2025.
Kehua’s new-generation liquid-cooled cluster-level management PCS boasts excellent grid-forming performance, robust liquid-cooled heat dissipation, ultimate protection reliability, and flexible adaptation efficiency. It adopts ultra-high power density design, reducing costs while improving equipment operational efficiency. It possesses full-domain grid-forming support capabilities, with millisecond-level power response and microsecond-level voltage construction, supporting adaptive wide short-circuit ratio, multi-coordinated group black start, and network-level black start. The new product employs full liquid-cooled heat dissipation + new cold plate patent design, operating at full capacity at 50℃ without derating and extending system lifespan by 25%+. With IP66+C5 anti-corrosion composite protection, it easily withstands harsh environments. It is compatible with both large and small cell systems, supporting 2h/4h scenarios. Optional AC-DC integration and box-type transformer integrated machine solutions enable extremely simple layouts and rapid deployment.
In the industrial-commercial PV-storage-charging solution exhibition area, Kehua displayed products such as the 36kW string inverter, new-generation 125kW string inverter, S³-EStore industrial-commercial energy storage system, energy management system, and megawatt split-type DC charger.
For industrial-commercial scenarios, Kehua offers multiple PV inverters to adapt to different working conditions. The industrial-commercial scenario series inverters ensure stable operation in various extreme environments with their wide temperature range stable operation capability, high protection grade, and adaptive thermal management system.
In terms of energy storage, Kehua’s S³-EStore industrial-commercial energy storage integrated machine adopts liquid-cooled temperature control technology and high energy density design, comprehensively building a solid safety defense line. Its millisecond-level grid-connected/off-grid seamless switching technology sets a new industry benchmark. This industrial-commercial PV-storage system solution offers significant overall advantages and is suitable for various scenarios such as factories, commercial complexes, and ecological farms.
