9.16 Information on dynamic feed-in

9.16.1 Control behaviour
With a system output of 7 kWp and above, a digital feed-in meter or a remote control option is still mandatory at present.
Active power limitation is the simplest option here. This can be achieved for all NX3 devices via the Smart-Meter or a data
logger.
