160kWh Commercial Energy Storage System Installed in Nigeria | GSL High Voltage Battery & 100kVA PCS

Customer Background

The client is a mid-sized commercial facility in Nigeria, where unreliable power supply and soaring diesel prices have long disrupted operations and raised costs. As the business expanded, stable electricity became a critical need for maintaining productivity, protecting sensitive equipment, and reducing fuel expenses.

Challenges & Needs

Despite having backup diesel generators, the site faced:

Frequent power outages from the national grid, affecting workflow and increasing downtime.

Heavy diesel consumption leads to unsustainable operating costs and environmental concerns.

A need for a scalable energy storage system that could manage peak loads, support essential loads during blackouts, and integrate with their existing PMS/EMS infrastructure.

Demand for a safe, space-efficient, and high-voltage LiFePo4 battery solution that could be expanded in the future.

The GSL ENERGY Solution

After detailed consultation and system design, GSL ENERGY proposed and delivered:

4 sets of 40kWh high-voltage rack-mounted LiFePO4 battery systems (Total: 160kWh)
Seamless integration with Sinexcel 100kVA bidirectional PCS (power conversion system)
Full support for PMS (Power Management System) and EMS (Energy Management System) connection
Multi-layer protection design: overvoltage, overcurrent, short circuit, and thermal management
Modular rack-based structure for easy maintenance and space-saving installation
OEM customization: Rack cabinets matched the client infrastructure with tailored interface ports and smart monitoring

Implementation Highlights

From logistics, on-site installation, system configuration, to commissioning, the entire project was completed quickly and efficiently.

Our engineering team collaborated closely with local technicians to ensure fast adaptation and technical training.

Despite a high-temperature operating environment and tight installation space, the modular high-voltage solution fit perfectly with zero civil rework needed.

Real-time data access and system diagnostics are now available via remote monitoring and on-site touchscreen displays.

Results & Business Value Delivered

Diesel usage reduced by over 70%, delivering rapid cost savings
100% uptime for critical equipment, regardless of grid failures
Payback period estimated under 3 years, thanks to fuel and downtime savings
Energy storage autonomy up to 8 hours, covering off-peak and backup operations
Improved energy visibility and load management via PMS/EMS integration

“GSL ENERGY's battery system was exactly what we needed. It has stabilized our energy flow and cut diesel use massively. Their team worked fast, understood our constraints, and delivered beyond expectations.”
— Facility Manager, Client in Lagos, Nigeria
