Solar-Powered RS485 to NB-IoT / 4G Converter – Industrial RS485/UART Cellular

The Solar-Powered RS485-NB Industrial Converter is a rugged outdoor device that converts RS485, Modbus, and UART sensors into NB-IoT / LTE-M / 4G cellular devices — perfect for remote, off-grid locations where power and connectivity are limited.

Equipped with an integrated solar panel and high-capacity rechargeable Li-ion battery, this unit provides continuous, maintenance-free operation for years. Its IP67 waterproof enclosure ensures reliability in harsh environments such as irrigation sites, farms, water systems, pump stations, industrial facilities, and remote infrastructure.

The converter supports Modbus RTU, UART sensors (3.3V/5V) and interrupt inputs, making it compatible with a wide range of industrial and environmental equipment. Controllable 3.3V and 5V sensor power outputs allow efficient powering of external devices while maximising battery endurance.

Communication is handled via NB-IoT / LTE-M / 4G, offering excellent coverage and deep penetration across Australia. Configuration is quick via Bluetooth v5.1, and the device supports wireless OTA firmware updates for simple fleet maintenance.

All ProSense IoT hardware — including this unit — is fully compatible with ProSight Software, providing dashboards, alerts, charting, reports, and remote system commands.

For integrators, the converter can also be easily integrated into your own IoT or SCADA system using MQTT, HTTP, or UDP protocols.
