Huijue Group’s “Oil-to-Light Storage” Base Station Energy Solution

Despite the widespread coverage of global power and communication networks, approximately 789 million people in regions such as Asia, Africa, and the Middle East still live in areas without electricity or with unstable power supply. Communication base stations in these regions primarily rely on diesel generators (diesel engines) for power. It is estimated that over 500,000 communication sites worldwide operate diesel engines year-round, significantly increasing operators’ operational costs and maintenance pressures.

In some regions like Africa, diesel prices can reach as high as $1 per liter, resulting in enormous energy costs for the “24/7” operation of communication base stations. Diesel generators have high failure rates, leading to rising maintenance costs and frequent outages. Over 80% of communication interruptions are caused by untimely maintenance of diesel generators. Additionally, diesel generators produce noise pollution and high carbon emissions, failing to meet global low-carbon and energy-saving policy requirements, thereby exacerbating environmental pressure on communication companies.

HuiJue’s customized site energy solutions address operators’ pain points

As a solutions provider with years of experience in the energy and communications sector, HuiJue Technology Group has thoroughly analyzed the characteristics of sites in regions such as Africa, the Middle East, and Southeast Asia. By considering factors such as on-site environmental conditions, energy policies, and return on investment, the company has developed a hybrid energy solution for communication base stations that transitions from diesel to photovoltaic and energy storage systems.

This solution utilizes HuiJue’s self-developed intelligent hybrid energy control system, integrating photovoltaic power generation, lithium-ion battery storage, and emergency diesel generator backup power, helping operators transition from “heavy oil dependency” to “solar-storage-based power supply,” achieving multiple objectives of cost reduction, efficiency improvement, and green upgrading.

Four core advantages:simplicity, efficiency, environmental friendliness, and intelligence

Modular design supports installation in multiple scenarios, including micro-stations, standard stations, and dual-warehouse stations;

Standardized core equipment supports 48V DC systems and oil generator interconnection;

Easy installation, compact size, and compatibility with multiple station types, including ground-mounted, tower-mounted, and rooftop-mounted;

Easy to expand, with multiple devices supporting parallel operation to meet power growth needs.

Efficient operation, significant energy savings

Utilizes high-efficiency MPPT tracking algorithms, achieving up to 99.8% photovoltaic utilization;

Equipment self-consumption power as low as ≤6W, overall conversion efficiency ≥97%;

Photovoltaic input supports 250V high voltage, simplifying wiring structure and reducing line losses;

Energy storage system coordinates with the grid/diesel generator for efficient energy utilization.

Green and environmentally friendly, primarily replacing diesel

The system’s main power source is photovoltaic + lithium-ion battery storage, with the diesel generator serving as an emergency backup;

Compared to lead-acid batteries, HuiJue lithium-ion batteries offer a longer service life and higher energy efficiency;

Achieves “24/7 diesel-free operation” for communication base stations, actively responding to the “dual carbon” strategy;

Reduces carbon emissions and noise pollution, aligning with environmental regulations and social responsibility requirements.

Intelligent operation and maintenance, cost reduction and efficiency improvement

The entire station is connected to the HuiJue HJ-EMS energy management system, enabling remote centralized monitoring;

Real-time monitoring of battery status, fault alerts, and equipment operation data is supported;

Remote start/stop, strategy configuration, and operation optimization are supported, reducing on-site human intervention;

Unmanned stations become possible, significantly reducing OPEX maintenance costs.

Case results: Large-scale deployment with significant benefits

Currently, HuiJue’s site energy system has been commercially deployed on a large scale in Africa, the Middle East, Southeast Asia, and other regions, helping many mainstream operators around the world complete the “oil-to-light storage” upgrade of more than 1,000 sites and achieve “zero oil generator operation” in multiple scenarios, greatly alleviating maintenance pressure.

According to customer feedback, this solution saves over USD 9,000 annually per site in fuel costs, labor, and spare parts, with overall savings exceeding 50%, significantly enhancing site operational profitability.
