Grid and Plant Protection (NA Protection) correctly implemented

Grid and plant protection (NA protection) is a mandatory safety component for decentralized power generation plants (PV, BHKW, wind) to ensure grid stability and safety.

Central NA Protection

For plants with a capacity of more than 30 kVA, a central NA protection according to VDE-AR-N 4105 is required in Germany. This device monitors voltage and frequency and disconnects the plant from the grid in case of deviations.
