Project Overview

Project Location: Matunggong, Kudat, Sabah, Malaysia
Application: Off-grid solar power system for small business
Solar Capacity: 15kWp solar PV system
Energy Storage Capacity: 60kWh LiFePO₄ battery storage
Battery System: 6 × 10kWh GSL ENERGY Wall-Mounted Solar Batteries
System Type: Off-grid solar + battery energy storage system
Solution Provider: GSL ENERGY

In Matunggong, Kudat, Sabah, Malaysia, a local business owner was looking for a reliable energy solution to support daily operations on a remote property. Due to the high cost and complexity of extending utility grid cables to the site, connecting to the traditional power network was not an economically viable option.

To achieve energy independence, the customer selected a 15kWp off-grid solar system integrated with a 60kWh GSL ENERGY LiFePO₄ battery storage solution, creating a stable and sustainable power supply for the property and business activities.

The system uses six units of 10kWh wall-mounted solar batteries connected in parallel, combined with an off-grid inverter, allowing the customer to store solar energy during the daytime and use clean power throughout the night or during periods of low solar generation.

Reliable Energy Independence for Remote Areas

For many remote properties in Sabah, Malaysia, grid connection can involve significant infrastructure investment, including long-distance cable installation, construction work, and ongoing maintenance costs.

Instead of relying on expensive grid expansion, the owner of this small business chose an independent solar energy solution.

The installed system consists of:

• 15kWp solar photovoltaic panels for renewable energy generation
• 60kWh GSL ENERGY LiFePO₄ battery storage system for energy backup
• 6 × 10kWh wall-mounted batteries for modular energy expansion
• Off-grid inverter system for stable AC power output
• Intelligent battery management system (BMS) for safe operation and monitoring

This configuration provides sufficient stored energy to support essential business loads, reducing dependence on diesel generators or unstable power sources.

60kWh Modular Wall-Mounted Battery Storage Solution

The energy storage system is built with six GSL ENERGY 10kWh wall-mounted LiFePO₄ batteries.

The modular battery design provides several advantages:

Flexible Capacity Expansion

Each 10kWh battery module works independently with intelligent BMS protection. Multiple batteries can be connected in parallel according to actual energy requirements.

For this project, six battery units were combined to create a 60kWh energy storage bank, providing enough capacity for continuous off-grid operation.

Safe LiFePO₄ Battery Technology

The system adopts lithium iron phosphate (LiFePO₄) battery chemistry, known for:

• High thermal stability
• Long cycle life
• Excellent safety performance
• Reliable operation in solar storage applications

This makes it suitable for long-term residential, commercial, and remote power applications.

Space-Saving Wall-Mounted Design

The compact wall-mounted structure helps optimize installation space. The batteries are neatly arranged inside the dedicated equipment room, creating a clean and organized energy storage area.

Designed for Malaysia’s Remote Environment

Sabah’s tropical climate brings challenges such as high humidity, heavy rainfall, and remote terrain conditions. For this project, the off-grid solar battery system was designed to provide stable electricity under local environmental conditions.

The customer no longer needs to depend on grid availability. Solar energy generated during the day is stored in the battery system and supplied to electrical loads whenever needed.

This improves:

• Energy reliability
• Power availability
• Operational independence
• Long-term electricity cost control

Supporting Sustainable Off-Grid Living and Business Operations

With the completed solar-plus-storage system, the customer has achieved a higher level of energy independence while reducing reliance on conventional electricity sources.

The 60kWh battery storage capacity enables the business to operate with greater confidence, even in areas where grid infrastructure is limited or unavailable.

This Matunggong project demonstrates how distributed solar energy storage systems can provide practical solutions for rural communities, remote businesses, and off-grid properties across Malaysia and Southeast Asia.
