Data Retrieval from Old SMA Inverter Using AC Energy Meters
August -2021


How It Works
There was no ⛔direct communication method available for extracting energy data from an SMA 3kW solar inverter, which was connected to several solar panels, this particular model lacked such functionality.
I was tasked 🚩 with finding a solution to track the energy being generated.
To gather the necessary data, I installed AC energy meters (PZEM-004T) on each of the phases connected to the inverter. By summing the data from each meter, I was able to calculate the total energy delivered by the inverter. This energy data was then sent as a </> POST request to our local API for further processing.
