On December 18, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the General Administration of Quality Supervision, Inspection and Quarantine jointly released the "Notice on Printing and Distributing the Implementation Rules for the Energy-Efficient 'Leader' System of Five Products, Including Electric Washing Machines and Lighting Products, and the Selection of Energy-Efficient 'Leader' Products." This move marks a significant step forward in promoting energy-efficient appliances in China.
In the coming months, the selection process for energy-saving "leader" products will begin for electric washing machines, lighting products, household refrigerators, flat-panel TVs, and speed-controllable room air conditioners. Alongside updating the 2015 version of the "Leader" system for refrigerators, flat-panel TVs, and inverter air conditioners, the three ministries have expanded the program to include electric washing machines and lighting products under the energy-efficient "Leader" initiative.
One of the most notable changes in the 2017 implementation rules is the increased application threshold. Previously, appliances needed to meet energy efficiency level 2, but now they must achieve level 1 under the current national standards. Additionally, the evaluation criteria have been revised, with a focus on energy efficiency, green technologies, and innovation capabilities.
For example, refrigerator applications now require higher energy efficiency standards, with points allocated for energy-saving technology, environmental protection, and innovation. The scoring system includes factors such as energy efficiency levels, green technologies, and enterprise innovation. Each category has its own weight, ensuring that only the most efficient and sustainable products qualify.
The new rules also introduce more detailed evaluations for other products like inverter air conditioners and flat-panel TVs. For instance, inverter air conditioners are now evaluated based on standby power consumption, while flat-panel TVs are assessed on image and sound quality. These changes reflect a growing emphasis on both performance and sustainability.
Although the incentive measures remain largely unchanged from the 2015 version, they still provide strong support for selected products, including recognition and priority procurement by government agencies. The updated rules will be valid for five years and will replace the previous version once implemented.
This expansion of the "Leader" system to include washing machines and lighting products is a major development. Washing machines must meet specific criteria, such as rated washing capacity and water-saving features. The evaluation process also considers technical aspects like energy efficiency time and water content, as well as health and environmental protection features like sterilization or no-clean technology.
Moreover, applicants must commit to shipping at least 10,000 units of each product model within one year of being listed. This ensures that only viable and mass-produced models are included in the program.
Overall, these updates signal a stronger commitment to energy efficiency and sustainability in China’s appliance industry, encouraging manufacturers to innovate and improve their products for a greener future.
Solar Inverter
A solar inverter converts direct current (DC) electricity from solar panels into alternating current (AC) for use in homes and businesses.
Usage:
Solar inverters are used in both residential and commercial solar power systems to convert the electricity generated by solar panels into a usable form for powering homes, businesses, and other facilities. They are an essential component of grid-tied solar systems, off-grid solar systems, and hybrid solar systems.
Working Principle:
Solar inverters work by using a process called "pulse width modulation" to convert the DC electricity generated by solar panels into AC electricity. This involves rapidly switching the DC input to create a waveform that mimics the characteristics of standard grid electricity. The inverter also synchronizes the output with the grid frequency and voltage to ensure compatibility with the existing electrical infrastructure.
Purpose:
The primary purpose of a solar inverter is to enable the use of solar energy as a practical and reliable source of electricity for residential and commercial applications. By converting the DC electricity generated by solar panels into AC electricity, solar inverters make it possible to power appliances, lighting, and other electrical devices with clean, renewable energy from the sun. Additionally, solar inverters also provide monitoring and control functions to optimize the performance and efficiency of the solar power system.
