【 摘 要 】

In this paper, a new smart monitor and control system has been designed for injected power application to grid from a three-phase photovoltaic inverter (a smart monitor and control system (SMCS)). The system consists two main units. Firstly, the control system unit: this unit connects directly to the inverter to measure the output voltage of three-phase photovoltaic inverter and the control circuit, It can turn the inverter 'on' or 'off' from a long distance. Secondly, the monitoring unit: this unit is designed to monitor the states of the photovoltaic inverter system from long distances. It has two monitoring options OLED and a smartphone monitoring application. LoRa technique (long range) used to send and receive data between controllers system and monitoring system. LoRa is a new type of wireless communication technology within the Internet of Things (IoT). The SMCS application has been designed by using open source software "MIT App Inventor 2"; this application is used to sends and receives the data from a control unit by using Bluetooth as a wireless communication in order to monitor and control the whole system. The main advantage of the SMCS that it can monitor and control three-phase photovoltaic inverters that have been installed in remote and rural areas.
