    • Start the configuration interface of the my-PV device.
    • Enter the IP address range of the home network or the network in which the my-PV device is located.

    Activate communication via Modbus TCP

    • If necessary, add further devices (inverters, battery storage, etc.) to the search. Instructions for connecting additional devices can be found under Connecting devices.
    • Click on Search and install devices.
    • After successful installation, the device is listed under the heating elements device class with the message Device is installed.

    House consumption

    • Classify the device according to the electrical installation. As a rule, the assignment must be made under Devices registered by the main meter.
    • Complete the configuration according to the house installation. You can find instructions here: Smart Setup

    Display and optimization in the SOLARWATT Manager portal

    Once the my-PV device has been integrated into the Smart Setup, its consumption is displayed in the SOLARWATT Manager portal in the Analytics section under Consumption.

    Due to the infinitely variable power setting, the my-PV devices are ideal for consuming excess PV power yourself. The power consumed is transmitted to the Manager flex. This regulates the heating element according to freely definable switching criteria.

    The switching criteria can be set in the SOLARWATT Manager portal in the energy optimization area.
