Built for Flexible Energy Deployment
The DQ1911 storage system is designed for flexible residential and light commercial deployment, delivering stable and reliable power where efficiency, scalability, and energy independence matter most.
Backup Power
Keep refrigerators, lighting, internet devices, air conditioners, and other essential loads running during outages to maintain daily comfort. For an average household, the system can provide essential backup power for more than 30 days, while the stackable design saves space and allows easy installation even in compact areas.
Solar Self-Consumption
Store excess solar energy during the day and use battery power first at night to continuously supply household loads while reducing grid dependence. For users in high electricity-cost regions, the system can significantly increase solar self-consumption, lower long-term energy bills, and improve overall return on investment.
Off-grid Living
Provide stable independent power for rural homes, small farms, islands, and areas with unreliable grid access. The modular stackable design allows capacity to expand based on actual energy needs, enabling users to build a complete off-grid energy system without a large upfront investment.
Remote Monitoring & Maintenance
With WiFi, GPRS, or RS485 connectivity, users can monitor system performance, battery status, and energy usage in real time, even when away from home. Early fault alerts help users respond quickly and make daily energy management more reliable and worry-free.
Designed for Faster Installation, Lower Costs, and Scalable Projects
Benefits for Installers
70% Faster Installation
Modular & stackable design reduces installation time by over 70% and lowers costs and complexity.
Flexible Scalability
Four configurations with up to 6 units in parallel for flexible system scaling.
Lower After-Sales Costs
Remote diagnostics reduce service visits and after-sales costs.
Reduced Project Risk
All-in-one design reduces compatibility issues and improves reliability.
The Smarter Choice for Home Energy Storage
From installation time and labor cost to efficiency and long-term operating expenses, DQ1911 outperforms traditional systems and diesel generators—helping installers and homeowners reduce costs and improve overall system performance.
