Protected Supply of Control Circuit for Standalone IoT Applications in Microgrids

This paper shows a circuit concept that can be used for supplying and protecting low power and low voltage self-powered devices which are employed in automation scenarios specific to Internet of Things (IoT). The proposed architecture consists of photovoltaic panels, a battery system, the protection circuit as well as an IoT device, thus allowing for independent control and measurement of various processes that are present in renewable-only microgrid applications.
