Testing of energy storage | TÜV Rheinland

Optimizing energy storage systems with our expert testing and certification

Your commitment to safe, efficient, high quality energy storage systems benefits customers, the planet and the health of your company. An integral part of that commitment is third-party testing and certification of your energy storage systems and components, and selecting the right partner makes a difference.

With extensive experience in the solar industry, our experts test and certify both photovoltaic battery energy storage systems and individual components, such as the battery, management system, inverters and interfaces. Based on recognized standards our tests focus on safety, grid conformity and efficacy.

Our internationally respected test mark proves to customers and authorities that your systems have been tested for compliance with current applicable standards and reflects your dedication to optimizing your PV energy storage products.

Our energy storage system certification hones your competitive edge

When you choose to work with us to test and certify your energy storage systems, you gain access to our substantial experience in the wind and solar industry. We can provide you with unmatched expertise as you strive to attain the highest quality and safety standards in the field.

Not only does our test mark distinguish you from competitors and send a strong signal to customers, we save you valuable time and expense by assisting you from the design and development stage onward.

We provide comprehensive energy storage system testing

Our approach to PV energy storage testing and certification begins at the earliest stages of development and continues throughout production. The process involves:

  • Review of documents for completeness and plausibility
  • Testing based on existing standards
  • Preparation of test reports
  • Factory inspection
  • Certification


For the certification of stationary local battery energy storage systems, we take into account the following standards:

  • UN 38.3: Safety requirements for the transport of lithium batteries
  • IEC 62619: Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for secondary lithium cells and batteries
  • EN 50272-2: Safety requirements for secondary batteries and battery installations
  • VDE AR 2510-50 for energy storage system with lithium batteries
  • BATSO 02 2014: Manual of Evaluation of energy system


Moreover, we are offering the following additional tests:

  • Inverter testing for safety and grid conformity according to EN 62109-1/2, VDE-AR N 4105 and VDE 0124-100 and other standards.
  • UN 38.3. Safety requirements for the transport of lithium batteries
  • Individual tests (e.g. vibration, shock, climate, IP protection, EMC and electrical safety)
  • Support and development assistance from the design stage onward
