Background
▪ In remote areas without grid power, base stations typically rely on diesel generators for power generation. The electricity produced is then converted into -48V power through rectifier modules to supply communication loads. This applies to base stations in regions such as high mountains, deserts, grasslands, and border areas in Chinese provinces like Tibet, Yunnan, and Inner Mongolia, as well as in overseas locations with limited or no grid coverage, including parts of the Middle East, Africa, and Southeast Asia.
▪ Paint point of diesel generator power supply system:
- The diesel fuel is expensive and is also vulnerable to theft;
- Operation requires frequent and costly fuel deliveries and faces storage challenges;
- Diesel generator causes significant environmental pollution of both noise and large amounts of carbon dioxide;
- Continuous operation leads to accelerated generator wear, shortening its lifespan and driving up maintenance expenses;
- The AC power generated must still be converted to DC via rectifiers, resulting in energy waste.
Introduction of Telecom Solar-Diesel Hybrid System Solution
▪ The system add solar and energy storage system based on the existing power supply system;
▪ The system consists of photovoltaic panels, a base station controller, lithium batteries, and a DC/DC module. The specific configuration will vary depending on the actual application scenario;
▪ The system prioritize photovoltaic power supply during the day while charging the energy storage battery, and switch to energy storage battery power supply at night. A diesel generator provides backup power when the batteries are low.
Components
Application
▪ High solar exposure, with annual direct sunlight exceeding 1,000 hours.
▪ Unobstructed space available for panels and equipment, free from shading by trees, buildings, or other structures.
▪ Absence of extreme environmental factors such as typhoons, heavy sandstorms, or locations above 5,000 meters in elevation.
