The project combines the grid connection and off-grid switching system with the energy management system, applied to a solar power station as a supplement to the existing solar power system.
- Project Introduction
This project is located in a sun-rich area of Nigeria and is an expanded energy storage system that supports its existing solar power station. The project integrates a grid connection and off-grid switching system with an energy management system, helping the client maximize the use of solar power generation.
- Project Details
2.1 Application
The energy storage system is primarily applied to a solar power station in Nigeria as a supplement to the existing solar power system. Previously, the solar power station could only provide power during the day, but with the introduction of the energy storage system, the solar station can store excess electricity and use it during peak demand or at night, achieving higher energy utilization efficiency.
2.2 Installed Capacity
The project is configured with 8 units of 215 kWh energy storage cabinets, with a total energy storage capacity of 1720 kWh (or 1.72 MWh).
2.3 Main Equipment
- Energy Storage Cabinets: 8 units of 215 kWh dual-chamber outdoor energy storage cabinets, with an IP65 protection rating.
- Grid Connection and Off-Grid Switching System: Supports flexible power scheduling, and the system can automatically switch to grid-connected or off-grid mode based on power demand.
- Energy Management System (EMS): Installed in the distribution cabinet, it monitors the real-time operation status of the energy storage system, optimizes the charging and discharging process, improves energy storage efficiency, and extends battery life.
- Solar Radiation Sensor: The project is equipped with a solar radiation sensor that can monitor the solar radiation intensity in real-time, providing accurate input data for the energy management system to help optimize the coordination between photovoltaic generation and energy storage.
