Industry Background

In remote and off-grid areas, telecom base stations are typically powered by diesel generators. The generated AC power must be converted into -48V DC to supply telecom equipment.

Such sites are common in mountainous regions, deserts, grasslands, border areas (e.g., Tibet, Yunnan, Inner Mongolia), as well as most off-grid locations in the Middle East, Africa, and Southeast Asia.

However, diesel generator systems face several major challenges:   High fuel costs and frequent fuel theft, leading to rising OPEX;  Difficult fuel transportation, with high logistics costs and storage challenges;  Environmental impact, including noise, fumes, and significant CO₂ emissions;  Low reliability, as generators wear out quickly under long-term operation;  Low energy efficiency, since generated power still requires rectification to DC.

With increasing pressure to reduce operational costs and boost clean energy usage, traditional diesel-powered base stations require transformation.

Solution Overview: Solar-for-Diesel Replacement

The EverExceed Solar-for-Diesel replacement solution upgrades existing power systems by integrating solar generation and energy storage, significantly reducing generator runtime and lowering OPEX.

System Operation

Daytime:Solar energy powers the telecom load and simultaneously charges the lithium battery.

Nighttime:The battery discharges to supply power continuously.

Backup Mode:When the battery reaches a preset depth of discharge, the diesel generator automatically starts as a backup source, mainly used to recharge the battery.

This dramatically reduces generator working hours—typically by 60–90%.

This hybrid architecture (PV + Battery + Diesel) ensures clean, stable, and cost-efficient base station power.

Suitable Application Scenarios

This solution is ideal for telecom sites with: 

High solar irradiation (>1000 hours/year) 

Sufficient space for solar panel installation

Minimal obstruction (no surrounding trees, buildings, chimneys)

Moderate environmental conditions (no extreme typhoons, severe sandstorms, or >5000m altitude)

High fuel costs or challenging fuel logistics

A need to reduce OPEX and increase renewable energy share
