Three Phase Inverter

X3-FORTH

  • 75kW / 80kW / 100kW / 110kW / 120kW / 125kW / 136kW / 150kW

Available in 75kW to 150kW, the X3-FORTH series features a compact, lightweight build with advanced heat dissipation—over 5% smaller and lighter. Smart air cooling extends fan life, while I-V curve diagnosis and night-time reactive power compensation boost system efficiency and stability.

Achieving up to 99% efficiency, the X3-FORTH supports 150% PV oversizing and 110% output overloading. With 12 MPPTs, 32A per tracker, and a 180–1000Vdc MPPT range, it offers flexible, high-performance energy generation for commercial solar systems.
