Monitoring of a solar installation with 24V 330W panel, Tracer4210AN MPPT controller, 12V 138Ah battery and 12V 1000W inverter (connected to load terminal). Used STM32F103 to decode controller data and get inverter current and SIM808 GPRS module to commun

Test channel data from SIM808

GPS-GSM

Test Only

Use Arduino Uno and SIM808 to transfer data to server

DS18B20 temperature sensor, Arduino nano and SIM808 GPRS module
