Digital inputs

Select use of digital inputs on the Smart Communication Board (terminal X401).

INFO

The settings in this menu can only be configured after logging in as the installer.

Parameter	Function
External battery management	If you have activated external control via the digital I/O ports in the Battery settings menu, you can define the functions of the inputs here. Assign the desired charge or discharge power to the inputs.
Power limitation according to §14a EnWG	For connecting an FNN control box with standard switching specifications and additional control in accordance with Section 14a. Observe the instructions for the FNN control box provided by the manufacturer and whether the connections match the selection made here. In accordance with Section 14a, it must be possible for devices which draw energy from the public grid, such as heat pumps, wallboxes or a battery that is connected to the inverter and can be charged from the grid, to be limited by the energy supplier (power reduction). If power reduction is active, the current max. amount that can be drawn according to Section 14a is 4200 W. Ask your energy supply company what power limit you should set. Max. rated input (W): Here enter the power limit in accordance with Section 14a. This is the max. power with which energy may be drawn from the public grid via the inverter if the energy supplier has activated power reduction. Activate Allocation of control signals for active/reactive power control. Activated: If a ripple control receiver or FNN control box is connected to the inverter, the control signals of the FNN control box are distributed in the local LAN network by means of UDP. Other inverters can therefore also be controlled via the connected FNN control box. Deactivated: The control signals are not distributed in the local LAN network by means of UDP.
Power limitation with FNN control box	For connecting a FNN control box (connection via S1/S2/W3/W4) with standard switching specifications and additional control in accordance with Section 14a. Observe the instructions for the FNN control box provided by the manufacturer and whether the connections match the selection made here. In accordance with Section 14a, it must be possible for devices which draw energy from the public grid, such as heat pumps, wallboxes or a battery that is connected to the inverter and can be charged from the grid, to be limited by the energy supplier (power reduction).
