Communication gateway WebdynSunPM

IoTtelemetryMQTT

Product overview
The WebdynSunPM 4G concentrator is a gateway for monitoring and controlling photovoltaic installations. It collects and analyses data from inverters, meters and sensors, and executes power management strategies to modulate grid injection, optimise storage and manage self-consumption. Configuration is available locally via the embedded web server and wizard, and remotely when required. Data can be sent to one or two servers or stored locally on a micro SD card.
