Overview of ripple control receiver/control box, also with power limitation in accordance with Section14a
INFO
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 power reduction in accordance with Section 14a, the following connection should be provided for the ripple control receiver/control box.
The energy supplier then limits the inverter’s power. If the energy supplier sends the power limitation signal to the inverter’s digital inputs via the ripple control receiver/control box, the power drawn from the grid is limited in accordance with Section14a of the German Energy Industry Act (EnWG).
The maximum rated input should be configured in the Webserver after commissioning by going to General > Digital inputs > Power limitation according to Section 14a. This should currently be limited to a maximum of 4200 W.
If power limitation is active, a battery connected to the inverter can only be charged from the grid using the set maximum power.
