The is a critical German technical application rule that sets the minimum requirements for connecting and operating power generation systems (like solar PV and battery storage) in parallel with the low-voltage distribution network. It serves as the national implementation of the European "Requirements for Generators" (RfG) code. 📋 Core Scope and Application reactive power management
