Energy efficiency testing results released! Huawei's industrial and commercial network type energy storage LUNA2000-241 series demonstrates its strength

On March 28, 2026, the energy efficiency testing results of Huawei's industrial and commercial network type energy storage LUNA2000-241 series were released, including rated energy efficiency (similar to RTE) test and 24-hour comprehensive energy efficiency (2 charging and 2 discharging) testBoth core indicators were tested by China Electric Power Research Institute's Weikai Testing, marking Huawei's leading technology in the field of industrial and commercial grid type energy storage, which has once again been witnessed by professional third-party testing institutions.

Rated energy efficiency refers to the ratio of output energy to input energy during the charging and discharging cycle of an energy storage system at rated charging and discharging power. It is the core indicator for measuring the economic efficiency of energy storage. In the field of industrial and commercial energy storage,Low energy efficiency and system losses will seriously constrain the development of the industryMeanwhile, during the operation of the systemThe increase in internal resistance and uneven temperature control can also lead to accelerated energy efficiency degradationAfter only three years of operation, some systems have experienced a significant decline in efficiencyExtending the investment return cycle affects the overall economic viability of the project.

This test includes the following two experiments:

　　Rated energy efficiency test

According to the testing method of GB/T 36548-2024, the rated energy efficiency of Huawei's industrial and commercial network type energy storage LUNA2000-241 series was tested. The testing process includes three consecutive charging and discharging cycles with rated charging and discharging power, with a 2-hour static period between each cycle. The tests are conducted at rated charging and discharging power of 108 kW and 54 kW, respectively. This testing method does not calculate the static loss, but focuses on the energy efficiency performance during the charge discharge cycle, truly reflecting the energy efficiency of the system during the charge discharge cycle (similar to a single RTE).By taking the average of three charge discharge cycles, the accuracy and reliability of the test results are maximally ensured, providing a scientific basis for evaluating the economic efficiency of energy storage systems for industrial and commercial users.

　　24-hour comprehensive energy efficiency (2 charging and 2 discharging) test

　　forTo better simulate real-life scenarios, Huawei has proposed a 24-hour comprehensive energy efficiency (2 charges and 2 discharges) detection method, which simulates the typical daily 2 charges and 2 discharges of industrial and commercial users to detect energy efficiency. This method specifically calculates the energy consumption of auxiliary power sources within 24 hours, including the losses during the idle period.This inspection conducted a rigorous 24-hour comprehensive energy efficiency (2 charging and 2 discharging) test on the Huawei Industrial and Commercial Network Energy Storage LUNA2000-241 series, using Huawei's defined calculation method to obtain the 24-hour comprehensive energy efficiency ηIndicators have a direct impact on user returns and investment payback periods.

After testing, the Huawei Industrial and Commercial Network Energy Storage LUNA2000-241 series demonstrated excellent performance in this test, with rated energy efficiency (similar to RTE) reaching 91.03% and 92.38% at rated charge and discharge power of 108kW and 54kW, respectively(Above the industry average of 87%)The 24-hour comprehensive energy efficiency (2 charging and 2 discharging) reached 90.31% and 91.99%, respectively. This breakthrough achievement is attributed to Huawei's innovative wind liquid intelligent cooling and heating management architecture, which ensures that the system operates at the optimal temperature while reducing auxiliary power consumption, improving system life and reliability. The above performance not only reflects Huawei's technological leading advantage in network type energy storage products, but also demonstrates Huawei's digital energy's strength and confidence in continuously promoting industry innovation and helping customers achieve green and low-carbon transformation, serving thousands of customers in various industriesBring higher investment returns and shorter payback periodsHuawei's digital energy will continue to pass throughTechnological innovation drives high-quality development of the industry.

　　Xing Jun, General Manager of Weikai Testing Technology Co., Ltd., stated that,As an authoritative third-party quality and technical service organization that integrates basic research, standardization, testing, certification, inspection, metrology, capability verification, and quality improvement extension services (laboratory technical services, training, etc.), China Electric Power Research Institute Weikai Company is honored to provide Huawei with this testing service. After our two professional and rigorous tests, the test results fully verified Huawei's technical expectations for its industrial and commercial network type energy storage LUNA2000-241 series. In the future, we will also continue to witness the emergence of more new technologies and products with Huawei.

　　Cai Xu, General Manager of Huawei China Digital Energy Intelligent Photovoltaic Industry and Business Expansion Department and Partner Ecological Development DepartmentThis is not only an authoritative test of Huawei's energy storage technology, but also the best affirmation of the team's three-year hard work. The rated energy efficiency of 92.38% (under a rated charge and discharge power of 54kW) is not the "ideal value" in the laboratory, but a "solid" result that can withstand rigorous third-party testing. Huawei will continue to be guided by the "visionary strategy" and work with partners to serve more industrial and commercial customers with higher quality products.
