Iraq Residential Energy Storage Project: 120kWh Home Battery System by GSL ENERGY

In Iraq, where erratic power supplies have long coexisted with high temperatures, an increasing number of households are installing home energy storage systems to ensure a reliable supply of electricity for daily use.

In 2025, GSL ENERGY successfully installed a 120kWh home energy storage system at a local residence. By connecting six 20kWh wheeled lithium-ion batteries in parallel, the system provides users with a stable, sustainable power supply, enabling greater energy independence.

Project Overview

 Project Location: Iraq

 Application: Commercial power supply / Backup power system

 System Capacity: 120kWh Battery

 Product Model: GSL-W-20W (51.2V 400Ah)

 Deployment Date: March 2026

System Architecture: 6 x 20kWh wheeled batteries in parallel

This system is specifically designed for domestic use, balancing high capacity, stability, and flexible scalability, making it suitable for detached houses, large-scale residential properties, or households with high electricity consumption.

Customer Requirements: Enhancing household energy security and independence

Against a backdrop of an unstable local grid, the customer aims to achieve the following through the deployment of a residential energy storage system:

 Maintain the normal operation of critical household loads (air conditioning, lighting, refrigerators, etc.) during power cuts

 Reduce reliance on the grid and enhance energy independence

 Ensure long-term stable operation of the system in high-temperature environments
