Description

Connection to Modbus RTU (485) inverter interface.

Connection Sungrow Com2 connector A1+B1 (data logger connection).

Attention not for Modbus TCP Winet S2.

A few values such as mains connection and total DC are on other registers.

MPPT 3 can now be read out and running state for battery charge and discharge can be read out.

Unfortunately, these values cannot be read via Winet S2 and Modbus TCP with the current Sungrow firmware.

  1. Charging with Loxone. RTU actuators

    Hello is there a way to control the actuators? At the moment I can only see the sensors and can display the data, but it is not possible to build intelligent solutions with dynamic electricity tariffs?

      Hello Mr. Altmann, currently the control via Modbus is not entered into the program. We are currently clarifying the data points for control with Sungrow and hope that we can adapt the module. If you already have data points, you are welcome to send them to us for incorporation.

    2. Maximilian Altmann

      unfortunately i don´t have the data points Currently i am facing another problem. The sensor "Batterie Leistung" always show a positive value, so the Loxone "Speicher Zähler" doesnt know if the battery is charging or discharging, do you have a solution for that?

      Maybe this PDF helps? https://github.com/BigWanna/Sungrow-ModbusRegister-/files/13242230/TI_20231019_Communication.Protocol.of.Residential.Hybrid.Inverter_V1.1.2_EN.pdf

    Hi, what does "Leistung Netz" deliver? In my config there are 375 MW of flow displayed instead of the correct 1 kW that is flowing. Why is that so?
