Why Choose the X3-ULTRA?

The X3-ULTRA is a commercial and industrial energy-storage solution suitable for factories, shopping centres, offices, and warehouses.

Its 3 MPPTs maximise solar energy generation and improve compatibility with complex photovoltaic systems. If one MPPT experiences a fault, the operation of the other PV arrays is not affected.

A 200% oversized PV input allows the system to allocate up to 100% of the available power to AC output and up to 100% to battery storage.

This ensures that the available solar energy is fully utilised, converted into AC power, and efficiently stored in the batteries.

Power can be allocated independently to each phase and controlled down to 0 W per phase. The system supports an output of up to 10 kW on a single phase, helping reduce dependence on the utility grid.

Microgrid Function

The microgrid function allows the hybrid inverter to simulate the utility grid and activate a string inverter during off-grid operation.

By connecting the string inverter to the EPS port of the hybrid inverter, the system can use photovoltaic or battery energy to power the string inverter during a grid outage.

Real-time data monitoring through SolaX Cloud helps streamline commercial and industrial energy-management processes.
