Growatt WIT 10K-HU 10kW - 3-Phase Hybrid LV Inverter

The Growatt WIT 10K-HU is a powerful 3-phase hybrid inverter for low-voltage battery systems (48V), specifically designed for residential and small commercial energy storage applications. With a rated output power of 10 kW, battery storage support, and an integrated backup function, this inverter delivers maximum energy independence and optimal use of solar power. It is suitable for both grid-connected and off-grid applications and features intelligent energy management to increase self-consumption.

Thanks to its dual MPPT trackers, a maximum recommended PV capacity of 16,000 Wp, and an efficiency of up to 97.6%, this hybrid inverter ensures maximum energy yield from any photovoltaic system. The integrated UPS (Uninterruptible Power Supply) function switches to backup power within 10 ms, ensuring that critical loads remain operational during power outages.

The inverter supports both lithium-ion and lead-acid batteries, offers a maximum charge and discharge current of 220 A, and provides a 100% unbalanced 3-phase output for maximum flexibility. In addition, it supports advanced features such as generator integration, AC coupling, smart load management, export limitation, and comprehensive monitoring via the Growatt Shine platform. Thanks to its robust IP66-rated enclosure, the inverter can be installed both indoors and outdoors.
