We have a total of around 20 solar panels on our roof which are connected to a 5kW inverter system (ZeverSolar) which is connected into the house and subsequently the grid.

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

MPPT Hybrid inverter

Display power output from solar powered battery bank. Producing power for 7 stage grid inverter. Output controlled by household power consumption masurement. (Current transformer)

Sending Sensor data values to the ThingSpeak channel for Remote monitoring.

Data from scanning JFY inverter @ 300ms and producing stats each minute
