This study designs and implements a monitoring system for stand-alone photovoltaic power system. The users can understand the characteristic of the photovoltaic power system and its operation stats through this monitoring system. The stand-alone photovoltaic power system consists of three groups of array solar panels, solar chargers, batteries, inverters and an Auto Transfer Switch (ATS). The monitoring system utilizes LabVIEW software to monitor solar panels voltage / current, charge voltage /current, discharge voltage / current and provide the reading of generated electricity. In this study, the total power of solar panels is 3.99 kW, the largest charging current can reach 25 A, the largest voltage is 300.5 V and the largest current is 1.85 A form solar panels. From the experimental results, the generated power can reach 3.12 kWh every day. Furthermore, the proposed monitoring system can record the information and data of the generating electricity completely, and they can be as the reference for the future research work.
