QA-series | 3.6kW/6.2kW zero export hybrid solar inverter support CT anti-backflow
Lithium Battery Auto-Restart Function
Product Highlights
Key Features
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.
