Connection for self-consumption control

The inverter offers the option of connecting consumers to the inverter via an external load relay or directly to the switched outputs (e.g. OUT1).

Connection options:

• Use of a load relay to decouple and control 230 V loads.
• Direct connection to the digital input's switched output, e.g. for a heat pump or wallbox or to the input module of a smart home system.

Check which connection method is required for the device. For more information, please refer to the manual of the device to be controlled.

Connection example with load relay:

• Load control operating mode: Here, an external load (e.g. washing machine or air conditioning system) is triggered.
• Events operating mode: As soon as an event is present, an external load (e.g. lamp or signal horn) is triggered.

Connection example, direct connection to the switched output via potential-free contact:

• SG Ready operating mode: Here, the switching signal (e.g. contact closes) for using the PV energy is transferred directly to the heat pump's digital input.
• Wallbox operating mode: The charging process is started as soon as the contact is closed. The wallbox offers a digital/signal input for this purpose.
• Events/external control operating mode: The external device is controlled via a digital/signal input. This can be, for example, a KNX control unit or another smart home system.

For the electrical connection of the self-consumption control, proceed as follows:

INFO

If loads need to be switched and require a higher load at the switched output than 24 V/100 mA, an external load relay must be installed between the inverter and the consumer. No consumers may be connected directly to the inverter.

In the case of loads or consumers that are controlled via a potential-free switching contact (e.g. SG-ready heat pump control or smart home systems), these consumers can be connected directly to the switched output.

Switched output load, potential-free:
Max. load: 100 mA
Max. voltage: 24 V (DC)
