Reliable and Stable Power Supply

The DQ1913 Energy Storage System ensures reliable backup power and intelligent peak shaving for industrial and commercial applications. Its DC-coupled architecture provides a higher DC/AC ratio and improved round-trip efficiency, while advanced fault protection, low battery cycling, and automatic current sharing across multiple parallel units guarantee stable and efficient energy delivery even under demanding load conditions.

Future-Oriented Value & Revenue

Beyond energy storage, DQ1913 represents a long-term energy asset. It can participate in demand response programs and ancillary service markets, creating additional revenue streams by feeding power back to the grid. Equipped with high-safety LiFePO₄ batteries and an advanced energy management platform, it offers long service life, low maintenance costs, and high reliability, supporting strategic energy planning for the next decade and beyond.
Sustainable and Eco-Friendly

Green Energy Transition

The DQ1913 ESS actively facilitates the transition to renewable energy, enabling efficient self-consumption of solar PV and wind energy while smoothing intermittent generation. By reducing reliance on fossil fuel generation and optimizing energy dispatch, it contributes to sustainable, low-carbon operations for industrial and commercial facilities.
