CEEMC
CEEMC is a service offered by TÜV SÜD, a globally renowned technical services provider. CEEMC certification is a certification service provided by TÜV SÜD for products sold in the Chinese market, particularly electronic and battery products. It aims to confirm that these products comply with relevant Chinese regulations, standards, and safety requirements.

CE
A CE certificate is a document provided by a Notified Body that certifies a product’s compliance with EU health, safety, and environmental regulations, allowing the product to be CE marked and freely sold within the European Economic Area (EEA). The CE mark itself is a declaration by the manufacturer of this conformity, rather than a quality seal, enabling market access and demonstrating adherence to legal provisions.

IEC
IECEE, the IEC System for Conformity Assessment Schemes for Electrotechnical Equipment and Components, is a multilateral certification system based on IEC International Standards. Its Members use the principle of mutual recognition (reciprocal acceptance) of test results to obtain certification or approval at national levels around the world.

MSDS
MSDS stands for Material Safety Data Sheet, which is a document now largely replaced by the Safety Data Sheet (SDS) to communicate information about the health and safety hazards of a chemical product. Provided by chemical manufacturers, MSDSs contain crucial details on a substance’s properties, potential dangers, safe handling and storage, and emergency procedures. While some existing MSDSs may still be in use, the standardized, 16-section SDS format, developed under the Globally Harmonized System (GHS), is now the international standard for hazard communication.

TÜV
“TÜV” (Technischer Überwachungsverein) refers to independent organizations in Germany that perform safety testing, certification, and inspections for products, services, and systems, and are internationally recognized for their quality standards. Key TÜV entities include TÜV SÜD, TÜV Rheinland, and TÜV NORD, which provide globally accepted certifications for various industries, including automotive, medical, IT, and energy. The term “TÜV” is also colloquially used in Germany to refer to the compulsory vehicle inspection.

Deye Whitelist
To get a Deye-whitelisted lithium battery, you must check the official Deye Inverter website for their latest approved battery list, as only batteries found on this list will receive official Deye after-sales service and warranty. Deye does not provide warranty for other brands that fail communication tests with their inverters.
