01
Voltage-stable adaptation
In-house stacked-PV MPPT controllers deliver precise voltage regulation for −48 V site busbars. High compatibility means little rewiring, fast retrofit, and stable site power.
Solar-for-Diesel Energy Scenario
The solar-for-diesel energy scenario is Huijue Technology’s green retrofit for diesel-powered base stations. PV, storage, and core controllers work together to replace diesel generation with clean energy—cutting consumption and cost while enabling low-carbon site operations.
Solution Positioning
This green upgrade package for diesel-powered base stations centers on “solar replacing diesel, storage topping up power, and lower operating cost.” It integrates PV modules, intelligent controllers, bidirectional power modules, and storage batteries into one green supply system. Automatically matching the site −48 V standard, it runs PV-first supply, surplus storage, and deficit top-up—solving high fuel use, heavy maintenance, and high emissions of traditional diesel sites, and delivering fast retrofit value in cost, carbon, and supply stability.
02
PV–storage complementarity
An intelligent PV–storage system dispatches energy dynamically: PV feeds loads first, surplus charges storage, and storage covers weak-light periods—cutting diesel starts and maximizing clean energy.
03
Lower cost and carbon
Clean PV–storage power replaces diesel, cutting fuel and maintenance spend plus exhaust and emissions—enabling low-carbon base-station upgrades.
04
Simple operations
Standardized modular design with high integration, fewer faults, and multi-layer protection supports 24/7 operation and less manned staffing.
Applicable Site Types: Traditional diesel-powered telecom base stations / Remote sites without grid power, diesel-dependent / Outdoor sites with weak grid needing diesel backup / Existing telecom sites needing low-carbon retrofit
System Operation Logic
The PV array outputs through an MPPT module with regulated voltage, feeding DC loads first and storing surplus in the battery bank.
In weak light, the storage battery discharges via a DC/DC module to cover the load gap.
Grid AC is converted through AC distribution and a switch-mode power supply into DC as last-resort backup, while also topping up site batteries.
The system automatically coordinates PV, storage, and grid power—prioritizing clean energy to keep loads online continuously.
