NA protection (grid and system protection) is a certified complete solution for the safe and standard-compliant grid connection of photovoltaic and generation systems. It continuously monitors the voltage and frequency of the power grid and automatically separates the system in the event of grid faults to prevent island operation and grid instabilities.
Systems with more than 30 kW require central NA protection in accordance with VDE-AR-N 4105, which is why operators need a reliable, easily integrated and standard-compliant solution. The use of NA protection simplifies planning and commissioning, saves time and ensures safe, compliant operation.
