Key Features & Technical Highlights

Dual MPPT for LV Three-Phase Systems

The SUN-18/20/21K-G04-LV series incorporates two independent MPPT trackers optimized for low-voltage three-phase grid connections. Each MPPT supports 3 strings (3+3 configuration), enabling flexible array designs across different roof orientations or partial shading scenarios.

With a wide MPPT voltage range of 200V to 700V and rated DC bus voltage of 350V, the inverter accommodates various string configurations while maintaining peak efficiency on LV 127V/220V and 133V/230V networks.

Industry-Leading Efficiency

Maximum conversion efficiency of 98.6% combined with MPPT tracking efficiency exceeding 99% minimizes energy losses throughout the system lifetime. This high efficiency directly translates to improved energy yield and faster return on investment for commercial installations.

Comprehensive Protection Suite

  • DC Side: Reverse polarity protection, surge protection (Type II), integrated DC switch
  • AC Side: Overcurrent, overvoltage, and short circuit protection with Type II surge protection
  • System Safety: Anti-islanding, residual current detection, insulation impedance monitoring
