Overview
- The DIN VDE V 0126‑95 product standard defines safety tests and connector limits for plug‑in photovoltaic devices and will take effect on December 1, 2025.
- Layperson connection via a Schuko plug is permitted up to 960 watts of module capacity and 800 watts of inverter output under the new rules.
- Use of manufacturer energy connectors such as Wieland or SEP is permitted up to 2000 watts of module capacity, after which systems are treated as conventional PV.
- Integrated battery versions are excluded from the standard and typically require a current sensor installed by a qualified electrician plus additional registration with the grid operator.
- Roughly 1.15 million plug‑in systems are registered in Germany, and VDE and industry groups say the clear standard should improve legal certainty and consumer confidence.
