With increasing electricity costs and growing concerns about energy reliability, more homeowners are exploring home battery storage systems to reduce dependence on the traditional power grid.
In Johor Bahru, Malaysia, the Tan family faced rising monthly electricity expenses caused by higher household energy consumption, especially during evening peak hours when air conditioning, appliances, and home office equipment were frequently used.
To achieve greater energy independence, they decided to install a wall mounted battery storage system integrated with their existing solar PV system.
The Tan family lived in a modern residential house equipped with rooftop solar panels. Although their solar system generated clean energy during the daytime, most electricity consumption occurred after sunset.
During daytime hours, excess solar power was exported back to the grid, while electricity had to be purchased from the utility provider during evening peak periods.
This created three major challenges:
- Increasing electricity costs during peak consumption periods
- Limited utilization of generated solar energy
- Lack of backup power during grid interruptions
The family needed a reliable residential energy storage system that could store surplus solar energy during the day and provide electricity when demand was highest.
To solve these challenges, a 10kWh wall mounted lithium battery energy storage system was installed.
The system included:
The lithium iron phosphate battery chemistry provides:
- Long cycle life
- Excellent thermal stability
- High safety performance
- Reliable daily charging and discharging
The system automatically stores excess solar power during daylight hours and supplies stored energy to household appliances at night.
This allowed the family to maximize solar self-consumption instead of relying heavily on grid electricity.
Compared with traditional floor-standing battery cabinets, the compact wall mounted battery design offered:
- Easy installation
- Reduced space occupation
- Modern residential appearance
- Flexible indoor and outdoor applications
After installing the home battery storage system, the Tan family achieved significant improvements:
By storing solar energy during the daytime and using battery power during peak hours, the household greatly reduced electricity purchases from the grid.
The solar energy utilization rate increased from approximately 40% to over 85%, allowing more renewable energy to be consumed locally.
During short-term grid outages, the battery system automatically supplied power to essential household loads, including:
- Lighting
- WiFi router
- Security systems
- Refrigeration equipment
- Essential home appliances
"Before installing the wall mounted battery storage system, we generated solar energy but still depended heavily on grid electricity at night. Now, most of our daily energy comes from our own solar system, and we have much better control over our electricity costs."
— Mr. Tan, Residential Energy Storage User, Malaysia
Across Southeast Asia, residential users are increasingly adopting solar battery storage systems as electricity prices fluctuate and energy independence becomes more important.
A modern hybrid solar battery system enables homeowners to:
- Store renewable energy
- Reduce electricity bills
- Improve backup power capability
- Increase solar energy utilization
- Build a smarter and more sustainable home energy system
For homeowners seeking reliable and efficient energy solutions, wall mounted lithium battery storage provides an ideal combination of safety, performance, and flexibility.
