Growatt WIT 12K-HU 12kW - 3-Phase Hybrid LV Inverter

The Growatt WIT 12K-HU is a powerful 3-phase hybrid low-voltage inverter (48V) designed for residential and small commercial energy storage systems. With a rated output power of 12 kW, battery storage support, and an integrated backup function, this inverter provides maximum energy independence and optimal use of solar energy. Suitable for both grid-connected and off-grid applications, it features intelligent energy management to increase self-consumption and reduce energy costs.

Thanks to its dual MPPT trackers, a maximum recommended PV capacity of 19,200 Wp, and an efficiency of up to 97.6%, this hybrid inverter maximizes the performance of any solar installation. The integrated UPS (Uninterruptible Power Supply) function switches to backup power within 10 ms, ensuring that critical loads remain operational during grid outages.

The inverter supports both lithium-ion and lead-acid batteries, offers a maximum charge and discharge current of 250 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.
