VDE tests and certifies balcony power plants

By testing and certifying balcony power plants on the part of the VDE, this protects consumers and grants them more safety. The VDE is developing a test specification with which balcony power plants can be evaluated as a complete system. Security for the retailer in accordance with the current legal basis and applicable regulations and standards is available.

(Frankfurt am Main, 07.09.2023) The VDE tests and certifies balcony power plants with immediate effect. The corresponding test specification was developed in accordance with the current legal basis and the applicable regulations and standards. It covers all components of plug-in mini power generation systems. This includes one or two PV modules, the cables and plugs, the inverter, the grid connection and the mounting system. This means that it is now possible for the first time through the VDE to test and certify balcony power plants as a complete system and not just individual components.

The VDE is also responding to numerous reports in recent weeks on safety deficiencies in mini PV systems. VDE CEO Ansgar Hinz: "Balcony power plants are very popular with consumers because they can actively participate in the energy transition by using them. We as VDE want to support this. For this reason, it is important to us that the new devices are safe for the user. Who if not we can guarantee this? The VDE has stood for protection and safety in electrical engineering for more than 130 years."

Increase protection and safety for users

A test specification with which the overall product balcony power plants can be evaluated has the advantage that not only the individual components per se, but also the interactions of the individual components with each other are taken into account. This increases protection and safety for users.

The VDE is committed to facilitating the installation and operation of mini PV systems without compromising on safety. At the beginning of the year, for example, we made proposals for improvements in a position paper, some of which were taken up by the legislature. Our standards organization DKE is also working on the first product standard for the complete balcony power plant product. We expect a result before the end of this year.
