Description

Growatt WIT 12K-HU hybrid inverter is the powerful centerpiece for your photovoltaic system with battery storage. With a rated power of 12 kW and a three-phase connection, this hybrid inverter reliably powers demanding households and commercial businesses with self-generated solar power.

Key Benefits for Your System

High overload capacity: With 200% overload for 10 seconds, you can easily start power-hungry appliances.
Reliable backup power supply: In the event of a grid outage, the device switches to backup power in just 10 ms.
Flexibly expandable: Up to 6 units can be connected in parallel, allowing your system to grow with your needs.
Robust and durable: The IP66 protection rating enables flexible installation even in demanding environments.

Intelligent Use of Your Solar Power

The Growatt WIT 12K-HU hybrid inverter combines your solar modules, battery storage, and the power grid into one efficient overall system. During the day, it converts the generated solar power and feeds surplus energy into your battery storage so you can use it in the evening. Thanks to a maximum efficiency of 97.6%, only minimal energy is lost. The 100% unbalanced output power allows each phase to be loaded up to half of the rated power – ideal for real load distributions in the household. Through the integrated generator input and intelligent load management, you always stay in control. This way, you increase your self-consumption, reduce your electricity costs, and gain a significant degree of independence from the public grid.
