The last couple of weeks I’ve been running monitoring software that is connected to the Aurora inverter and receives measurements from it. The setup is as follows:
A lot of measurements are available, such as voltage, current and power of both inputs (solar panel strings) and the grid, temperature of the inverter and its booster, etc. The most interesting graphs are shown below. The first one shows the energy produced on each day since the solar panels were installed.
The second one shows the power of a single day, from both the input (solar panel string) and the grid. There is a difference in these two readings, because the inverter is not one hundred percent efficient in transforming DC input into AC output.
The third one shows the voltage outputs of the solar panels. Although not perfectly stable, it tries to keep quite constant at about 200V.
The fourth one shows the current outputs of the solar panels. This is what matters for the production of the panels.
The fifth one shows the temperature of the inverter itself and its booster. It seems that the inverter tries to keep the temperature of the booster below 50 degrees. As soon as it hits 50 degrees, it cools down to 40 degrees and rises again.
