Test Bench for Off-Grid Photovoltaic System Based on Cloud Platform

Off-grid photovoltaic systems are widely used for power generation, especially in remote regions without the presence of an electrical grid. Thus, it is necessary that the power conditioning equipment of the off-grid system be efficient and robust to avoid maintenance. In this context, test benches are important to certify the efficiency curves of these equipment. Furthermore, it is interesting to have the test bench monitored and activated remotely, since off-grid systems are generally located in remote location and the battery charging/discharging tests are time consuming. This work aims to develop low-cost test bench to perform efficiency curves for batteries and off-grid system charge controllers. Furthermore, the test bench will be monitored remotely based on cloud platform. The results presents the possibility to perform the charging and discharging processes of the battery and send the measurements to the cloud. In addition, the presentation of the interface to the data visualization is presented in this work.
