Battery Solution
in Malaysia
Solar panels only generate power while the sun shines. A Battery Energy Storage System, or BESS, changes that completely. It stores your excess solar energy during the day. Then you use that power at night, during peak hours, or when the grid fails.
With AQ Energy’s BESS solutions, powered by Fox ESS, you gain true energy independence. Enjoy lower bills and reliable backup power around the clock.
What Is a Battery Energy Storage System (BESS)?
A Battery Energy Storage System, or BESS, stores electricity for you to use later. In a solar setup, it captures the surplus energy your panels produce. Instead of exporting all that power to the grid, you keep it in the battery. Then you draw on it whenever you need it, day or night. Modern systems like FOX ESS use lithium iron phosphate, or LiFePO₄, batteries. This chemistry delivers strong safety and a long service life.
A built-in Battery Management System, or BMS, also monitors performance constantly. As a result, it keeps your whole system running safely. In short, a BESS turns your panels into a round-the-clock power source. So your solar works for you long after sunset.
Benefits of BESS:
Why Add Storage to Your Solar Solution
Benefit 1Energy Independence
Use your own stored solar power instead of relying on the grid. Therefore, you take control of your daily energy supply.
Benefit 2Lower Electricity Bills
Store cheap daytime solar and use it during expensive peak hours. As a result, you cut your monthly electricity costs.
Benefit 3Reliable Backup Power
Keep essential appliances running during blackouts or grid outages. So your home or business stays powered when it matters most.
Benefit 4Maximise Self-Consumption
Use more of the solar you generate rather than exporting it cheaply. In turn, every panel on your roof works harder.
Benefit 5Protection From Rising Tariffs
Shield yourself as TNB electricity rates continue to climb. Consequently, your stored solar becomes even more valuable over time.
Solar + Battery Package
for Your Home
For homeowners, a battery means your solar keeps working long after sunset. During the day, your panels quietly charge the battery. At night, your home then runs on stored solar instead of grid power.
As a result, you buy far less electricity from TNB. You also gain valuable backup power during outages. So your lights, fridge and Wi-Fi keep running when the grid drops. For families who want lower bills and real energy security, storage is the natural next step. Therefore, it pairs perfectly with your rooftop solar system.
BESS
for Your Business
For businesses, a BESS is a powerful tool for controlling energy costs. It stores solar energy to offset expensive peak-hour tariffs. It also helps you manage high maximum-demand charges on your bill.
As a result, your business gains a clearer, steadier energy spend. Just as importantly, it provides critical backup power during outages. So you protect your operations from costly, unexpected downtime. Whether you run a factory, office or retail space, storage puts you in control. Moreover, it strengthens your sustainability credentials with customers and partners.
