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 15K-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 15K-HU is a future-proof solution for private and commercial PV systems with storage.

Why a hybrid inverter?
The WIT 5K-HU combines the functions of a grid inverter with integrated battery management. This allows you to store excess energy and retrieve it when needed. With support for DC-coupled and AC-coupled systems, the inverter is particularly flexible and future-proof – ideal for homes and businesses with growing energy needs.
Maximum Power Point Tracking
MPPT (Maximum Power Point Tracking) technology maximizes the energy yield of your PV system. With a maximum input current of 20A per MPPT, the WIT 15K-HU also supports modern, high-performance solar modules. The large MPPT voltage range from 150V to 850V ensures high efficiency even in partial shade or with variable module orientation.
Easy installation and smart control
With its compact design and IP66 protection class, the WIT 15K-HU is ideal for outdoor use. It can be easily integrated into energy management systems via MODBUS TCP. Optionally, you can connect the device to the Growatt Shine app via Wi-Fi or LAN to monitor the system online at any time.
