Recently, Beijing Jianheng Certification Center (hereinafter referred to as Jianheng Certification Center), a leading third-party testing and certification organization in China, has issued the first China-based Xinneng Gold Solar Certification for PV inverters to Huawei Technologies Co., Ltd. (hereinafter referred to as Huawei).
The certification is performed based on the new version of NB/T32004-2018 Technical Specifications for Grid-Connected PV Inverters, compared with the NB/T 32004-2013 Technical Specifications for Grid-tied PV Inverters, the new version of the standard enhances technical requirements for device adaptability, efficiency limit setting, and electromagnetic compatibility (EMC) test. Huawei inverters have withstood the tests of various indicators of the new energy standard and become the first enterprise in China to obtain the certification of the new energy standard for PV inverters, which fully proves Huawei's technical advantages in the inverter field.
The certified Huawei SUN2000 series smart inverters (5KTL-M0, 6KTL-M0, 8KTL-M0, 10KTL-M0, and 12KTL-M0) The industry's first AI-powered distributed PV inverter is the highlight. Intelligent arc detection (AFCI) based on AI technology, precise prevention, avoiding frequent false positives and eliminating fire hazards; The AI-enhanced intelligent grid-tied algorithm ensures network connection and adapts to complex grid scenarios. AI-powered Smart I-V Curve Diagnosis accurately locates PV string faults, improving O&M efficiency by 50%.
How to improve the inverter efficiency, enhance its adaptability and stability in different working conditions, and maximize the benefits of governments, enterprises, households, and investors in different application scenarios is a new opportunity for PV inverter enterprises to explore and develop continuously, and also a development bottleneck that urgently needs to be broken through. The new version of the standard improves the inverter's adaptability to the power grid, ensures that the inverter can run effectively in various working conditions, and reduces the number of startups and shutdowns. The new version of the standard not only extends the service life of the inverter, but also reduces the O&M cost, energy yield loss, and increases the enterprise's revenue. In addition, the new energy standard sets the average weighted efficiency limit, dynamic MPPT efficiency limit, and maximum conversion efficiency limit, which not only sets the minimum product performance from the technical perspective, but also ensures the energy utilization and gives end users the right to directly monitor the technology and market development, clearly understand the performance of the equipment used to protect the rights and interests of the end users.
In the wave of digital transformation, Huawei will continue to increase research and investment in the convergence of AI and PV technologies, build more competitive products and solutions, promote the transformation and upgrade of the PV industry towards intelligence, and accelerate the arrival of the era of grid access with parity.
