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.

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 HUADA Solar-for-Diesel replacement solution upgrades existing power systems by integrating solar generation and energy storage, significantly reducing generator runtime and lowering OPEX.
The system typically includes:
Solar PV modules
Telecom-grade MPPT controller
HUADA LiFePO4 battery energy storage system
DC/DC modules and distribution components
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
