Plug in solar rules in Germany

Inverter limit800 VA
Panels2,000 Wp by law; 960 Wp with a household Schuko plug under the product standard
RegistrationMarktstammdatenregister only, within one month of start
BatteriesNot covered by the product standard. Register the battery as its own unit; ask your grid operator.
Tenants and ownersPrivileged measure since October 2024: landlord or owners can refuse only for good reason

The product standard DIN VDE V 0126-95 (December 2025) allows a layperson to plug a system into a normal Schuko socket when the inverter delivers at most 800 VA and the panels total at most 960 Wp. Above 960 Wp the standard expects a special energy socket.

The law (Solarpaket I, May 2024) allows up to 2,000 Wp of panels with 800 VA. So 2,000 Wp on a Schuko plug is legal, but not standard compliant. In an insurance case, experts look at the standard.

Registration is a short online form in the Marktstammdatenregister of the Federal Network Agency. No separate notice to the grid operator is needed for the solar device itself.

800 VA, 960 Wp or 2,000 Wp? The German law and the German standard do not say the same thingGerman law allows 2,000 Wp of panels behind an 800 VA inverter. The new product standard accepts that only with a special plug. What this means in practice.Balcony solar in a rented flat or a shared building in GermanySince October 2024, landlords and owners' associations in Germany can no longer refuse a balcony system without good reason. What that means and how to ask.Adding a battery to plug in solar you already haveDC batteries between panels and micro inverter, all in one units and AC batteries on a socket: what each means for your inverter, the 800 W limit and registration.

Not yet confirmed

  • Whether a balcony battery must also be notified to the grid operator: sources disagree (federal ministry fact sheet versus ADAC).
  • Draft IEC 60364-7-751 could require a dedicated circuit in future.
