143kWh Off-Grid ESS in Burkina Faso | Reliable 24kW Solar Battery System

Solving Power Challenges in West Africa

In many regions of Burkina Faso, unstable grid infrastructure and frequent outages create significant barriers for residential, commercial, and industrial energy users.

To address this challenge, a 143kWh off-grid energy storage system (ESS) was successfully deployed, delivering stable, safe, and scalable electricity for continuous operation in remote environments.

This project demonstrates how low-voltage lithium battery systems combined with parallel inverter architecture can provide a highly reliable alternative to diesel-based power solutions.

Project Overview

Location: Burkina Faso

System Capacity: 143kWh

Output Power: 24kW

System Type: Low Voltage (51.2V) Battery System

Key Objectives

Ensure a 24/7 uninterrupted power supply

Reduce dependency on diesel generators

Enable long-term energy cost savings

Provide a scalable and easy-to-maintain solution

System Configuration & Technical Architecture

1. High-Capacity Lithium Battery Storage

Battery Type: LiFePO4 (Lithium Iron Phosphate)

Specification: 51.2V 280Ah per unit

Single Unit Energy: 14.34kWh

Total Units: 10 battery modules in parallel

Total Storage Capacity: 143kWh

This configuration creates a robust DC energy storage backbone, ensuring sufficient reserve for a long-duration power supply.

2. Parallel Inverter System for Redundancy

Inverter Brand: SunWell

Single Unit Power: 6kW

Quantity: 4 units in parallel

Total Output Power: 24kW

Key Advantages:

  • Enhanced surge capacity for heavy loads
  • Redundancy (N+1 design) ensures continuous operation
  • Maintenance without downtime
  • Even if one inverter is offline, the remaining units continue supplying power, critical for off-grid applications.

Key Technical Advantages

1. Low Voltage Design (51.2V) for Maximum Safety

Compared to high-voltage systems, the low-voltage architecture offers:

  • Reduced electrical risk during installation and maintenance
  • Simplified system integration
  • Better suitability for regions with limited technical infrastructure
  • This makes it an ideal solution for African and emerging markets.

2. Long Cycle Life & High Thermal Stability

The system utilizes LiFePO4 battery cells with:

  • 6000+ cycles lifespan
  • Excellent performance under high temperatures
  • Strong resistance to deep charge/discharge cycles
  • Result: Lower total cost of ownership (TCO) and longer service life.

3. Modular & Scalable Design

Plug-and-play battery expansion

Parallel architecture enables easy capacity increase

No need for major system redesign

Businesses can scale energy storage as demand grows, optimizing capital investment.

4. High System Availability with Redundant Design

The multi-inverter setup ensures:

  • Fault isolation
  • Continuous operation
  • Increased system reliability
  • Ideal for critical loads such as telecom, clinics, and remote facilities.
