Solar Inverter QA-series

Flexible Grid Interaction & Energy Trading

• Supports on-grid, off-grid, and hybrid modes. Enables battery-free operation and flexible adaptation to different scenarios. Battery power selling modes (SUF & PEC) support both energy storage and grid feed-in.

SiC Technology for Low Loss & High Efficiency

• Adopts silicon carbide (SiC) devices for higher efficiency, lower thermal loss, and reduced self-consumption. Ensures stable long-term operation with minimal overheating, noise, and failure rates.

Real-Time Monitoring via Smart APP

• Optional WiFi module enables real-time power generation monitoring, fault diagnostics, and error alerts. High-performance DSP improves system responsiveness and overall control accuracy.

Self-Consumption Priority, Grid-Compliant Control

• Built-in CT anti-backflow function intelligently controls power flow, prioritizes self-use, prevents reverse current, and complies with energy regulations. Fast response time of 20 ms ensures precise control.

Automatic Restart After Deep Discharge

• Compatible with multiple lithium battery brands. Supports intelligent battery activation and automatic restart after over-discharge using both PV and utility power.

Flexible Load Expansion Beyond Rated Power

• Supports unlimited load capacity through proper system wiring. Grid and PV power work together to supply excess demand without being limited by inverter rated output.
