Design and application of the photovoltaic inverter equipment monitoring system on Android platform

This paper presents the design and implementation of a photovoltaic inverter equipment monitoring system based on bluetooth technology on Android platform, including the inverter detector and the Android smart-phone. The inverter detector used STM32F103ZET6 as the main control chip. The real-time data received from inverter equipment were stored in AT45DB161 Flash chip and transmitted to the smart-phone via the bluetooth wireless link. Then, the smart-phone processed the received information and displayed it in graph view. Industrial applications show that the monitoring system has the advantages of high stability and performance, and the communication range reaches to about 100 meters in outdoor space.
