An often rudimentary IT structure with simple routers, minimal firewall protection and dial-up via openly accessible IP addresses without secure VPN access, as well as unsecured access to power plant components (e. via unencrypted WLAN) can become a security risk for the plant. This paper discusses the development of a two-way communication protocol between. Our PV Weather Boxes are the interface between weather sensors and the plant monitoring and deliver data to maximise the energy output. The portfolio offers certified and ready-to-use cabinets for PV power plants that meet the specific environmental, electrical and data transmission requirements. Photovoltaic system design represents a critical intersection of renewable energy technology, electrical engineering, and sustainable infrastructure development. The meticulous process of designing PV systems demands comprehensive understanding of solar resource assessment, electrical components.
