THE SOLUTION – RURAL, CONNECTED, AND POWERED
RedEarth chose our renowned connectivity device, the RUT240 industrial cellular router, to be installed in each of its energy storage systems. The router is connected via Ethernet to a RedPi – a custom device that connects to the storage system’s energy inverters via the Modbus RTU serial protocol.
The storage system is connected to solar panels that generate electricity when it’s sunny (i.e. most of the time), and the RedPi tracks energy generation and consumption data. The data is then transmitted to RedEarth’s cloud server in its Brisbane office via the secure and stable 4G network provided by the RUT240, with its WAN failover feature ensuring an uninterrupted connection. Lastly, the data is then analyzed and made available to the client via the dedicated EMU (energy monetization unit) mobile app.
Enabling the remote access itself is RMS Connect, via the SSH protocol. RMS Connect is one of the key IoT services of our Remote Management System, allowing for a unified access system for remotely reaching and updating connected smart devices, like the RedPi and RUT240. Using this service, RedEarth’s engineers can access and directly manage these end devices as though they were physically next to them – without even needing a public IP address or additional VPN services.
Importantly, RUT240 is an industrial-grade device ready to weather the adverse and arid environmental conditions of Australia. Temperatures in the summer can exceed 50 °C in the summer and drop below 0 °C in the winter. Luckily, the device has sturdy aluminum housing with plastic panels, making it perfectly functional between -40 °C to 75 °C.
Teltonika Networks was chosen to ensure this solution can reliably meet RedEarth client needs and remain relevant for future upgrades and development. It was important for RedEarth to work with a local team that understands Australia’s unique conditions and challenges, and our Australian team was more than happy to provide their expertise.
