DIY Installation of 10kWp PV Systems Under New Norms (heise.de)

• New standard separates DC capacity from AC output constraints.
• AC output limit remains strictly at 800W for simplified legal status.
• Strategic oversizing increases yield during suboptimal solar conditions.

"New regulatory standards for small-scale solar generators decouple DC module capacity from AC inverter output. While grid-feed is capped at 800W for simplified registration, users can install significantly larger solar arrays. This allows for higher energy yields in low-light conditions, enabling homeowners to maximize self-consumption efficiency without triggering the complex bureaucratic requirements of large-scale industrial installations."
