1. Project Overview

This project is located in Mauritania, Africa, providing an integrated power solution for local communication base stations. A total of seven equipment sets were installed. Due to the absence of grid support in the region, an off-grid system was adopted, combining photovoltaic power, energy storage, and diesel generators (a solar-storage-charging-diesel integrated system) to ensure stable operation of the base stations without grid connection.

2. Project Details

Application

This project addresses power supply challenges for telecommunication base stations in Mauritania. It delivers a flexible, reliable energy solution in off-grid environments by integrating photovoltaic systems, energy storage batteries, and diesel generators.

Primary Equipment

Cabinet: Outdoor cabinet, dimensions 2000mm (H) x 1500mm (W) x 800mm (D), constructed from galvanized steel.

Temperature Control Equipment: Includes 4 fans (DC 48V) and an intelligent thermostat.

Battery System: Lithium iron phosphate batteries (48V/155200AH) with extended charge/discharge cycle life.

FSU Monitoring Unit: EMS-B2010 for energy management and monitoring.

Hybrid Power System: Includes power distribution frames, photovoltaic modules, rectifier modules, and PV distribution boxes, supporting switching between different power sources.

Photovoltaic System: Includes 6 PV modules and PV mounting structures, delivering high efficiency.

Diesel Generator: 16KW/20KVA outdoor silent intelligent diesel generator with smart control system.

3. Project Advantages

Reliability: Utilizes an integrated photovoltaic-storage-charging-diesel design to ensure stable power supply, particularly in off-grid areas.

Flexibility: The system automatically switches power sources based on battery charge status, implementing an energy priority control strategy (PV > storage > generator).

Environmental Sustainability: Combining solar power generation with energy storage reduces reliance on traditional diesel generators, minimizing environmental pollution and energy consumption.

Intelligent Monitoring: Remote monitoring and management via the EMS system ensure efficient and stable system operation.
