How to Know if a Solar Panel Kit is Approved by Synergrid

In Belgium, for a plug-and-play solar panel kit to be legally connected to the electrical grid, it must be approved (homologated) by Synergrid, the federation responsible for technical regulations in the energy sector.

Here’s how to check if a solar kit is Synergrid-approved:

1. Check the Manufacturer’s Declaration

Each certified product should be listed with a valid C10/11 or C8/1 certificate provided by the manufacturer. This certificate proves that the inverter or microinverter used in the kit complies with Synergrid technical requirements.

2. Search the Official Synergrid List

Synergrid publishes official lists of approved devices:

• Go to the Synergrid website: synergrid.be

• Navigate to “Certificats C10/11” or “Homologation onduleurs”

• Look up the brand and model of the inverter included in the solar kit

3. Ask the Seller

Any trustworthy seller or brand (like Sunflower Solar) should be able to:

• Provide the Synergrid certificate

• Tell you if their plug-and-play kit complies with the latest Synergrid specifications

4. Make Sure It’s Up-to-Date

Standards evolve — ensure the certification is still valid under the current Synergrid version (e.g. Synergrid C10/11 version 9 or newer, depending on the year).

If you're in Belgium and planning to install a plug-and-play solar panel kit on your balcony, choosing a Synergrid-approved product is crucial to:

• Stay compliant with legal requirements

• Ensure a safe connection to the grid

• Avoid issues with your DSO (Distribution System Operator)
