Growatt WIT 4/5/6/8/10/12/15K-HU Hybrid-Wechselrichter 4/5/6/8/10/12/15kW 3-phasig
With the Growatt WIT 6K-HU hybrid inverter you get a powerful three-phase inverter that combines high energy yields, maximum flexibility, and reliable emergency power supply. Thanks to the DC/AC ratio of 1.6, you can make optimal use of your PV system and thus generate more energy. The inverter offers a maximum current per MPPT of 20A, supports a maximum PV input voltage of 1000V, and enables a charging and discharging current of 110A. In addition, it can be scaled up to 90 kW, supports DC and AC-coupled systems, and is compatible with multiple battery systems. With its UPS function, black start capability, and intelligent load control, the WIT 4K-HU is a future-proof solution for private and commercial PV systems with storage.
