Energy Storage Certification News

FAQs Must Both Grid-Connected and Off-Grid Modes Be Tested? Provide all declared operating modes and switching conditions. The test plan should select representative states accordingly to avoid overlooking safety risks under different directions of energy flow. 2026-09-11Read More FAQs Can an Inverter Certificate Still Be Used After Adding an Internal Battery? Integration changes electrical, thermal and control conditions. Check the original certificate’s scope and assess the added battery, charge and discharge paths and overall protection coordination. 2026-09-11Read More FAQs Is Additional Testing Needed If the Cells Change but Capacity Stays the Same? Cell internal resistance, protection characteristics, temperature limits and existing reports may differ. Submit the new cell information and assess battery pack and complete-product differences. Capacity alone cannot establish equivalence. 2026-09-11Read More FAQs Can a Portable Power Station Be Marketed Directly as a UPS? If uninterrupted power or a specific transfer time is claimed, define applicable loads and performance limits and verify those functions accordingly. Having a backup-power mode does not mean all UPS assessments have been completed. 2026-09-11Read More FAQs Is Environmental Testing Still Needed on a Sheltered Balcony? Select tests according to the environment specified in the operating instructions. Condensation, temperature changes, sunlight, humidity and possible rain exposure may still affect connector and enclosure protection. 2026-09-11Read More FAQs Does a CE Assessment Allow Grid Connection in Every Region? Product compliance and local grid connection are separate matters. Check grid parameters, installation and other applicable requirements against the sales country and actual connection conditions. 2026-09-11Read More FAQs Can a Balcony Battery Be Used with Any Microinverter? Check input and output voltages, currents, communications protocols, power limits and fault responses. Changes to the compatible equipment list require assessment of electrical compatibility and complete-product differences. 2026-09-11Read More FAQs Is an Auxiliary Vehicle Power Supply Classified as a Traction Battery? Distinguish them according to actual use. Auxiliary storage supplying living or work equipment differs in function and assessment route from a traction battery that drives a vehicle. 2026-09-11Read More FAQs Are Mobile Energy Storage Systems and Portable Power Stations Tested in the Same Way? Classification depends on capacity, weight, handling method, output interfaces and intended use. Mechanical securing and power distribution risks in trailer-mounted or large mobile equipment cannot be assessed simply as those of a handheld outdoor power station. 2026-09-11Read More FAQs Does Adding Battery Modules Affect the Original Assessment? Changes in module quantity may affect voltage, short-circuit current, heat dissipation and system control. Define the maximum expansion range in advance and assess representative configurations and tests for the differences. 2026-09-11Read More
