Battery Energy Storage

The Future of Reliable, Sustainable Power

Improve your grid stability and energy efficiency.

AJ Power QT (Quietude) Battery Energy Storage Systems (BESS) provide reliable, quiet and emissions-free power. Designed for environments where an Uninterruptible Power Supply (UPS) is critical or where power demand fluctuates, the QT range offers a flexible and dependable solution.

These systems support charging via renewable sources, the grid, or a generator, making them a more sustainable choice. Both single-phase and three-phase charging are supported for maximum compatibility.

When paired with a generator, the BESS ensures the generator operates only when necessary—typically just to recharge the battery. This minimizes generator run time and maintenance, while ensuring operation near peak fuel efficiency. The result: lower fuel consumption, reduced emissions, and overall cost savings.

The AJ Power QT range also features remote monitoring capabilities. Through a user-friendly web interface, users can track performance data, generate reports and receive real-time alerts, making site management simple and efficient.
