Product Overview

The Growatt WIT-XHU-US 480V Hybrid Inverter Series provides a flexible solution for high-power solar PV and energy storage systems requiring grid-connected operation, battery integration, and reliable backup power.

Seven power ratings are available—50kW, 63kW, 75kW, 85kW, 100kW, 125kW, and 150kW—allowing system designers to select the appropriate inverter capacity for a wide range of 480V three-phase installations.

With 10 independent MPPT trackers, the WIT series provides greater flexibility when configuring large PV arrays. Each MPPT supports up to 42A input current, 50A short-circuit current, and two PV strings.

The inverter also integrates directly with compatible battery energy storage systems through RS485/CAN BMS communication. Its 180–1000V battery operating range supports high-voltage battery configurations, while continuous charging and discharging power is available up to the rated power of the selected inverter model.

Reliable Backup Power

The WIT-XHU-US series is designed to maintain critical loads when grid power is unavailable.

Its backup capabilities include:

• Rated backup output from 50kW to 150kW
• 100% three-phase unbalanced load support
• ≤10 ms transfer time
• Built-in UPS functionality
• Black-start capability
• Up to 160% overload capacity for 10 seconds
• 3P3W+PE and 3P4W+PE load configurations

These capabilities make the WIT series suitable for installations that require both energy storage and high-capacity backup operation.
