Web enabled data logger for photovolatic inverter

Abstract

In recent years, the rapid development of technology makes human demand for energy and increasing reliance, leading to the rapid consumption of the world’s oil storage. Decades later, I am afraid that the global energy crisis will occur, so the development of alternative energy sources has become essential. Solar energy is inexhaustible source of natural energy if we can make full use of it, lack of energy issues will be resolved. However, solar energy still needed to be improved by monitoring the efficient. As a result, a web box is needed. In my project, a web box is made and it has the basic function of data logging such as data receiving, data sending, data saving in SD card, and data displaying(on board and website). Besides, for the safety purpose, the web box can monitor its temperature itself and it has a power state led light. For the maintenance purpose, it provided a self-test mode which can let user to ensure the application is function well before using it, also the web box provided a firmware update mode, it allow the using to update the firmware to repair or improve the firmware.
