Communication gateway WebdynSun

telemetryIoTGPRS

Product overview
The WebdynSun gateway monitors and collects performance and environmental data from solar plants. It aggregates indicators from inverters, electricity meters and environmental sensors (irradiance, temperature, wind speed, etc.) into CSV format and transmits them periodically via 4G/2G mobile networks, Ethernet or PSTN to a central server. Installation and configuration are performed via the embedded web server and can be executed locally or remotely. The gateway also supports remote-controlled local actions initiated by the central platform.
