Plug-in solar rules by country
The European Commission's Recommendation (EU) 2026/1007 of 30 April 2026 asks member states to remove obstacles for plug-in batteries and balcony solar up to 800 W. It is not binding, but most countries now use 800 W.
| Inverter | Panels | Batteries | Checked on | |
|---|---|---|---|---|
| Germany | 800 VA | 2,000 Wp by law; 960 Wp with a household Schuko plug under the product standard | Not covered by the product standard. Register the battery as its own unit; ask your grid operator. | 2026-11-07 |
| Austria | 800 W | Not fixed nationally; some grid operators expect at most 800 Wp for the simple route | Notify as part of the system; details differ by grid operator | 2026-11-07 |
| Switzerland | 600 W AC per metered circuit | Not capped by ESTI | Not covered by current rules; a new Swiss guideline is being drafted | 2026-11-07 |
| United Kingdom | 800 VA and 3.5 A, one device per household | Up to 2,000 W and four panels | Excluded from the plug-in route; a government safety study runs until 2028 | 2026-11-07 |
| France | No official plug-in limit found; the market uses 800 W | 3 kW threshold for free tolerated surplus (Energy Code L315-5, D315-10) | Not specifically regulated (unverified) | 2026-11-07 |
| Belgium | 800 W per household (per guides) | Not specified | Allowed when the battery inverter is on the Synergrid C10/26 list | 2026-11-07 |
