Product Details
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.
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.
Optional WiFi module enables real-time power generation monitoring, fault diagnostics, and error alerts. High-performance DSP improves system responsiveness and overall control accuracy.
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.
Compatible with multiple lithium battery brands. Supports intelligent battery activation and automatic restart after over-discharge using both PV and utility 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.
