Network and plant protection (NA) from enwitec. Depending on the national directive, generating plants must be shut down in the event of impermissible voltage or frequency deviations in the low-voltage grid. If the limit values permissible in the application rule are exceeded, the generation plant is automatically disconnected from the grid. If the mains voltage or mains frequency is back in the permissible range, the system is automatically switched on again. We offer both standard products and individual solutions, which are adapted to the needs of the respective photovoltaic system.
This network and system protection is specially built for the German and Austrian market, in accordance with VDE-AR-N 4105:2018-11 and ÖVE TOR R25 NS ASYNC .
