We have solar panels on our roof which are able to generate a peak power of 10 kW. An energy controller controls the converter, our heat pump and our battery with the goal that most of the solar energy is used locally. First we use the solar energy in our home, we charge the 230V-battery, and we load the heat storage tank. Only if even more solar power is generated we send the rest into the grid.
To visualize this and I am monitoring this system with PRTG using the Modbus protocol.
