Germany is the largest household storage market in Europe.

 

 

In 2022, the total installed capacity of household storage in Germany was about 220,000 units, accounting for 47% of the total installed capacity in Europe. in the first half of 2023, the installed capacity of household storage in Germany was 250,000 units, an increase of 170% year-on-year.

 

 

 

Germany is the global high ground for commercialization and standardization of energy storage applications, with more stringent standards than anywhere else.

 

 

 

 

 

Germany is almost ahead of the rest of the world in the fields of energy storage applications, quality control, technology development, and the development of safety standards for energy storage systems.

 

 

 

VDE-AR-E 2510-50 is a standard developed by the German Electrical and Electronic Association (VDE) specifically for lithium-ion energy storage safety, which is currently the world's first comprehensive assessment of energy storage standards. It puts forward strict technical requirements and test conditions for energy storage systems in terms of electrical safety, battery safety, electromagnetic compatibility, functional safety, energy management, transportation safety, environmental protection, etc., in order to ensure that safe and high-quality energy storage systems can enter the market.

 

 

 

The 2PfG 2698 and 2PfG 2511 standards set by TÜV (German Technical Inspection Association) are also the official German energy storage certification standards, while EN 62109-1/2, VDE-AR N 4105 and VDE 0124-100 are the official German inverter certification standards.

 

 

 

By obtaining the above German certifications, the company is not only authorized to enter the German market, but also proves that its energy storage products have the quality assurance to meet the tests of the global market.

 

 

 

The German market is a must for many energy storage companies, but due to its stringent entry certification standards, there are no more than 20 companies with greater competitiveness in the market.
