Hybrid Inverter

X3-ULTRA

  • 15kW / 19.9kW / 20kW / 25kW / 30kW

The X3-ULTRA offers unparalleled flexibility, supporting up to 10 units in parallel for both on-grid and off-grid systems.  With its 36A PV input per MPPT, it supports high-power solar panels. The advanced microgrid and generator functionality further enhance its adaptability, making it an excellent solution for residential, commercial, and industrial installations alike.

Product Advantage

The X3-ULTRA supports 200% PV oversizing for 100% AC output and battery storage. With 2/3 MPPTs, it ensures fault tolerance and maximizes power generation. The microgrid feature allows off-grid operation, using PV or battery energy to power string inverters during outages, reducing grid dependency.
