A large commercial complex in Lagos, Nigeria integrates shopping malls, restaurants, office buildings and underground parking lots, with strong and concentrated EV charging demand. The local public power grid is unstable, with frequent power outages and voltage dips, which seriously affect the safety and experience of EV charging. The developer needs a high‑reliability, intelligent and expandable EV charging energy solution.
Location/Time: Lagos, Nigeria, August 2025
Configuration: PCS: 600kW, BAT: 1800kWh, PV: 500kW, Backup Diesel Generator: 400kW
Load: High-power DC charging piles, commercial lighting, air conditioning, elevator systems, monitoring and security equipment
Operating environment: Central urban area, high temperature, humid, heavy load fluctuation, high requirement for stability and safety
Operating modes: Off-grid operation, solar energy priority, energy storage for peak regulation and voltage stabilization, backup generator automatic start to ensure uninterrupted power supply for the whole complex and EV chargers.
The system adopts high integration, low noise and intelligent control. It can support simultaneous super fast charging of dozens of electric vehicles. The energy management system optimizes the power distribution between commercial load and charging load to avoid overload.
The solution completely eliminates the impact of power outages. The complex operates continuously and stably, and EV charging service is highly praised by customers. Annual energy cost is reduced by 55%, and the project becomes a benchmark for green intelligent commercial energy systems in West Africa.
