Monitoring interfaces enable the interaction between the human operator and the monitored process. This role acquires special relevance for advanced scenarios like microgrids and renewable energiesbased facilities, which involve a large amount of magnitudes and energetic interactions. This paper performs a brief survey about monitoring interfaces applied to DC microgrids and photovoltaic systems. The software environments that are used and graphical design aspects are studied and reported. Furthermore, an experimental case applying an open-source suite (Grafana) to a DC microgrid is expounded.
