Why X3-ULTRA

Introduces a new C&I energy storage solution, suitable for factories, malls, offices, and warehouse. 

With 2/3 MPPTs, it maximizes power generation, enhancing compatibility with complex solar systems. 

Even if one MPPT encounters a fault, it won't affect the operation of other arrays.


200% oversized PV input = 100% AC Output + 100% Battery Storage

We ensure every unit of solar power is fully utilized, converted into AC output and stored in batteries efficiently. 

Power is allocated independently to each phase, controllable down to 0W per phase, with a max.10kW output on a single phase, reducing grid reliance.


Highlighting our micro-gird function. 

The micro-grid feature enables the hybrid inverter to simulate the grid and activate the string inverter when off-grid. 

By connecting the string inverter to the hybrid inverter's EPS port, it can use PV or battery energy to power the string inverter during utility outages.


Leveraging real-time data detection through our SOLAX Cloud streamlines commercial and industrial management processes.
