DG-SRTU Solar Telemetry Terminal

The solar energy system comprises two main components: the solar power supply system and the RTU system. The solar power supply system converts solar radiation into electrical energy, uses a solar charge controller to efficiently charge the batteries, and supplies power to the RTU system. The RTU system collects and stores data from the water meters and periodically uploads this data to the user platform.

Measurement principle

The solar energy system comprises two main components: the solar power supply system and the RTU system. The solar power supply system converts solar energy into electrical energy, uses a solar charge controller to efficiently charge the batteries, and supplies power to the RTU system. The RTU system collects and stores data from the water meters and periodically uploads this data to the user platform.

Key Features

Discharge Control Corrected by Battery Discharge Rate Characteristics

It features protection functions such as overcharge, overdischarge, load short-circuit, overload, and reverse polarity protection for photovoltaic cells.

A series‑connected PWM charging method, with four distinct charging stages, can extend the service life of storage batteries.

The LED indicator displays the battery status, allowing users to easily and intuitively monitor the battery’s operating condition.

It employs industrial-grade chips, enabling seamless operation in cold, high-temperature, humid, and rainy environments.

Features a digital LED display and intuitive one-touch setup for convenient, straightforward operation.

IP67 protection rating
