Power limitation in accordance with Section14a - only applies to Germany

The power limitation in accordance with Section14a applies to all operators of controllable appliances commissioned after 1 January 2024.

If the energy supplier requires a reduction in power in accordance with Section 14a, the following connection must be made for the ripple control receiver/control box.

The power limitation of the inverter is carried out by the energy supplier. If the energy supplier sends the power limitation signal to the digital inputs of the inverter via the ripple control receiver/control box, the power consumption from the grid is limited in accordance with Section 14a of the German Energy Supply Act (EnWG).

After commissioning, the maximum power consumption must be configured in the web server under Service > General > Digital inputs > Power limitation according to §14a or Power limitation with FNN control box. Currently, this is limited to a maximum of 4200 W.

If the power limitation is active, a battery connected to the inverter can then only be charged from the grid with the set maximum power.
