Description

Growatt WIT 8K-HU is the powerful three-phase hybrid inverter for anyone who wants to use their solar power efficiently and combine it with a battery storage system. With 8 kW AC rated power, two MPP trackers, and an integrated backup power function, this Growatt inverter is ideal for demanding photovoltaic systems in residential and commercial applications.

Key Benefits for Your System

High overload capability: 200% of rated power for 10 seconds handles even demanding inrush currents.
Reliable backup power supply: In the event of a grid outage, the WIT 8K-HU switches to backup operation in just 10 ms.
Flexibly scalable: Up to 6 units can be connected in parallel, and a generator input is integrated.
Robust and low-maintenance: IP66 protection rating and intelligent air cooling allow for flexible installation.

Smart Use of Your Solar Power

A modern hybrid inverter ensures that your valuable solar energy doesn't flow unused into the grid, but is instead stored and used specifically when you need it. The Growatt WIT 8K-HU fully automatically manages the interaction between photovoltaics, battery storage, and the household network. Thanks to compatibility with lithium-ion and lead-acid batteries as well as RS485/CAN communication with the BMS, the storage system is always kept optimally charged. With a maximum efficiency of 97.6%, almost no energy is lost. This noticeably reduces your electricity bill and gives you a significant degree of independence from the public grid. Via Wi-Fi or LAN, you can conveniently monitor your yield and consumption at any time.
