CT Anti-Backflow ProtectionPF 1.0 High-Efficiency Inverter DesignExternal WiFi Communication (Optional)Built-in BMS Communication for Lithium Batteries

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.

Flexible Grid Interaction & Energy Trading

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.

SiC Technology for Low Loss & High Efficiency

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.

Real-Time Monitoring via Smart APP

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.

Self-Consumption Priority, Grid-Compliant 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.

Automatic Restart After Deep Discharge

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.
