Anyone considering a battery storage system for their company today cannot ignore China. The largest and most competitively priced manufacturers of Battery Energy Storage Systems (BESS) are located in Asia. For German companies, the real challenge is no longer the technology itself, but the journey to get it: choosing the right manufacturer, ensuring compliance, and bringing the goods into Germany legally.
This is exactly the path we take at Kaiserberg every day. We import battery storage systems from Asia and already have the right manufacturers on hand. In this article, we show you what really matters when importing.
The market for battery storage literally exploded in 2025. Around 315 GWh of BESS were delivered worldwide, an increase of nearly 50% compared to the previous year. At the same time, system prices have dropped to about $117 per kWh, a decline of roughly 31%. In December 2025 alone, China installed 65 GWh of grid storage.
This dynamic is also reflected among manufacturers: six of the ten largest battery manufacturers worldwide are from China, led by CATL and BYD. Other well-known names in the commercial and large-scale storage market include Hithium, Envision, Pylontech, and Sungrow. For German companies, this means the largest selection, the most advanced LiFePO4 technology, and the best prices are found in Asia.
But this is exactly where the real work begins. Ordering from the first available supplier risks poor quality, missing documentation, and, in the worst case, a storage system that cannot even be legally placed on the market in Germany.
Battery storage systems are not ordinary import products. The EU Battery Regulation (Regulation (EU) 2023/1542) has been in effect since February 18, 2024. It creates a uniform set of rules for the sustainability and safety of batteries and explicitly applies to stationary energy storage systems, regardless of whether they were manufactured in the EU or imported. In Germany, the previous Battery Act (BattG) was replaced by the Battery Law Implementation Act (BattDG) on August 18, 2025.
The role you take on as a company is crucial. An importer is defined as anyone who places a battery from a third country onto the EU market. If the storage system is sold under your own brand, you may even assume the obligations of a manufacturer, regardless of who actually made the product. This includes, among other things:
Checking these requirements only after ordering will lead to problems. Compliance must be considered before selecting the manufacturer, not after.
Special rules also apply to transportation. A containerized battery storage system is transported as a Class 9 dangerous good under UN number 3536. The documentation requirements for such shipments were tightened once again on January 1, 2026.
In concrete terms, this means packaging, labeling, transport documents, and the choice of carrier must be correct from the start. Incorrect dangerous goods documentation leads to downtime at the port, additional costs, and, in cases of doubt, the rejection of the shipment. For a single storage project, this can upend the entire timeline.
These three exact points—manufacturer selection, compliance, and logistics—are where we come in. We import battery storage systems from Asia and handle the entire process from a single source:
The fact that we aren't just talking about theory is demonstrated by our own facility: we already operate five truck charging stations there in combination with a PV system. We know the practical side of charging infrastructure and storage because we built it ourselves.
Battery storage systems from China are highly attractive economically for German companies, technically mature, and available in a wide selection. The risks do not lie in the product, but in the process: in manufacturer selection, EU compliance, and dangerous goods logistics. Mastering these three points brings the full price and technology advantages in-house without the legal risks.
