FU-SUN-3.6/4/4.6/5/6K-G | 3.6-6KW | Single Phase | 2 MPPT

Higher yields / Safe & Reliable / Smart / User-friendly

The single-phase inverter is one of the best options for residential application thanks to its smaller size and local LCD display, buttons. Also, with built-in zero-export function (external CT is needed), it offers true ease and comfort for PV system operators and installers.

  • 2 MPP tracker, Max. efficiency up to 97.5%
  • Zero export application, VSG application
  • String intelligent monitoring (optional)
  • Wide output voltage range
  • Anti-PID function (Optional)
