The Challenge
Fadel Textiles, a mid-sized garment manufacturer in Lagos Industrial Estate, faced chronic grid instability—power outages averaging 6–8 hours daily forced reliance on diesel generators at ₦450/kWh effective cost. Production downtime and fuel expenses were eroding margins in a competitive export market.
The factory's 24/7 weaving and dyeing operations demanded a reliable, cost-effective energy backbone that could buffer grid failures, capitalize on rooftop solar potential, and cut diesel dependency without disrupting production schedules.
The WOWTIGER Solution
WOWTIGER's Lagos partner deployed a 50 kW / 120 kWh MAX Series containerized battery system paired with 80 kWp rooftop solar. The integrated solution provides:
- Seamless grid-solar-battery dispatch via built-in EMS controller
- Peak shaving during 7–10 PM utility tariff surge hours
- Diesel generator start/stop automation — battery bridges outages under 4 hours, eliminating short-cycle genset wear
- Remote monitoring and predictive maintenance through TigerCloud platform
Before WOWTIGER, we burned 2,800 liters of diesel monthly just keeping the lights on. Now our generators sit idle most days. The system paid for itself faster than we expected, and our export clients see us as a more reliable partner.

Within 12 months of commissioning, Fadel Textiles documented:
40% reduction in grid energy costs
Monthly utility bills dropped from ₦1.8M to ₦1.08M through peak shaving and solar self-consumption. Diesel consumption fell 78%, saving an additional ₦890K monthly.
Zero unplanned production stoppages
The battery's 4-hour autonomy covers 94% of grid outages without generator intervention. Quality rejection rates from voltage sag incidents dropped from 3.2% to under 0.5%.
18-month ROI
Total system cost of ₦38M repaid through energy savings by month 18. Projected 10-year NPV exceeds ₦120M at current tariff trends.
Technical Highlights
The MAX Series containerized unit integrates LiFePO₄ cells (6,000 cycle warranty), hybrid inverter, and SCADA-grade EMS in a weatherproof 20-ft frame. Installation took 8 days with zero production downtime. The system operates in ambient temperatures up to 45°C and interfaces with the factory's existing diesel ATS panel via Modbus RTU.
