ESP32 datalogger between Danfoss ULX 3600 inverter and Thingspeak / PVOut.
The Danfoss ULX 3600 is a single-phase Unilynx inverter that transforms the DC voltage (PV solar panels) to AC 230 voltage (Grid) and has an RS485 interface.
The ESP32 datalogger receives solar information (Power, Current, Voltage) from the inverter, shows real-time information on a oled display, saves it to EEPROM and uploads the data to ThingSpeak / PvOut.
All data (realtime and historical) is available in the cloud.
