Overview
- Under the new VDE product norm, systems that meet the standard may use a regular Schuko plug up to 960 W module power, with inverter output still capped at 800 W to the household grid.
- Above 960 W module capacity, a recessed or equally safe specialist connector such as Wieland remains required and must be installed by qualified professionals.
- The Bundesnetzagentur confirms that compliant plug‑in systems require only registration in the Marktstammdatenregister, whereas setups with storage must always be reported to the network operator.
- Retailers roll out steep deals, including 900–1000 Wp plug‑in sets for about €199–€299 (e.g., AC TEC, Kleines Kraftwerk, Solakon) and 2,000 W packages with storage for roughly €1,149–€1,299 (e.g., solago with Anker Solarbank 3 Pro).
- Vendors maximize yields by pairing higher module wattage with inverters limited to 800 W, though the Schuko threshold preserves simple plug‑and‑play only for lower‑power kits.
