On 17/10/2024, an amended edition (edition 2.3) of technical regulation C10/11 (connection of decentralised production installations) was published. In this edition, the obligation for a fixed connection was removed. This mainly impacts balcony PV systems and small mobile batteries with a household plug, but also bi-directional on-board chargers for electric vehicles, and for example mobile generators for construction sites and events.
From 17/10/2024, manufacturers of plug&play devices can submit a C10/26 homologation application
submit, and from 17/04/2025, C10/26-approved plug&play devices may be connected to an electrical installation.

Plug&play devices: Points of attention for users
There are a few special features that apply specifically to plug&play systems with a household plug:
• According to the AREI, these devices are considered to be a product, i.e. a mobile or transportable device that can be connected to an electrical installation via a socket. Consequently, when connecting such devices to an electrical installation, there is no obligation to carry out a conformity check prior to use (AREI Book 1, Chapter 6.4) or an inspection visit (AREI Book 1, Chapter 6.5), as is provided for electrical installations. However, it remains the responsibility of the owner, manager or operator of the electrical installation to which such devices are connected to ensure compatibility with and the impact of such a connection on his electrical installation, and if necessary to make the necessary changes to his electrical installation to ensure conformity with the AREI.
• Electrical equipment must comply with European regulations, including a CE marking and an EU declaration of conformity, and also with the general provisions of the AREI on electrical equipment connected to an electrical installation (see, among others, AREI Book 1, Section 1.4.2 Electrical equipment, and Section 5.1.3 Conformity with standards). The connection and use of electrical equipment must comply with the manufacturer's instructions for use and safety regulations. These aspects fall outside the jurisdiction of Synergrid.
• Regulation C10/11 ensures the stability and safety of the distribution network. The internal safety of the user's installation falls outside the remit of this regulation. It is therefore important for the safety of the user and his electrical installation to inform himself about the risks via the instructions for use and the manufacturer's safety instructions, and to strictly comply with the manufacturer's instructions in order to prevent dangerous situations.
• Other obligations and restrictions (outside the scope of this regulation) may apply to plug&play devices. If necessary, the user must obtain clear information about this in advance from the municipal urban development department in the case of balcony PV, the association of co-owners in the case of an apartment building, the landlord in the case of rental of real estate, the fire insurance company, etc.
