Abstract

This paper presents a solar inverter with the IoT interface. The intention is to build an inverter, which is used to interface a solar energy module to the power grid/load. The single stage boost converter and inverter are built eyeing cost efficiency and reliability. The control strategy for the Inverter should be in a way that, the required voltage and frequency (50 Hz) has to be supplied by the system. The IoT module measures the voltage, current and frequency of both inverter and the grid. The module also measures the temperature and the humidity of the system. The smart system measures the output power of the inverter connected to the grid. If the grid supply is off, the smart system turns off the inverter supply to the grid. Every value that are measured by the module are updated to the server, hence maintaining the database. The DSP TMS320LF2407A is used to generate the PWM signals for the inverter and boost converter. The Renesas micro-controller is used in the IoT module for measurement of the parameters. A battery bank is used for storage purpose. The Amazon cloud server is constantly updated through the GPRS module.
