Grid and system protection (NA) from enwitec. Depending on the national directive, generation systems must be switched off in the event of impermissible voltage or frequency deviations in the low-voltage grid. If the permissible limit values in the application rule are exceeded, the generation system is automatically disconnected from the grid. Once the mains voltage or frequency is back within the permissible range, the system is automatically switched back on. We offer both standard products and customized solutions that are adapted to the needs of the respective photovoltaic system.
This mains and system protection is specially designed for the German and Austrian market in accordance with VDE-AR-N 4105:2018-11 and ÖVE TOR R25 NS ASYNC.
