The photovoltaic system is not constant in power generation depending on the time or the surrounding environment. If an over-current occurs during the power generation due to an unexpected environment, or a short-circuit state occurs, the photovoltaic panel, Damage to the solar panel can significantly reduce the efficiency of the entire power plant or stop power generation. In order to cope with this situation, it is necessary to provide a system capable of managing and determining the abnormality of the photovoltaic power generation system, and further, a comprehensive monitoring system capable of monitoring the generated power is needed.
In a typical grid-connected photovoltaic power generation system, monitoring of the inverter is monitored using a local PC or web monitoring. In a large-scale power generation system, it is possible to monitor the system, but in an independent type solar power generation system in which a small-scale power generation is performed, monitoring is not performed due to an inefficient structure relative to investment costs.
In this paper, we design a small stand-alone photovoltaic power generation system that can be used for mountainous areas and camping, and study and implement a system that can easily monitor power generation, voltage current, temperature and humidity. The small stand-alone solar power generation system tracks the maximum power point of the solar power to raise the efficiency of energy production. The monitoring system is easily accessible by the user through the low-power network communication Bluetooth, It is expected to contribute to the market creation of power generation system.
