Description

Growatt WIT 4K-HU is a powerful three-phase hybrid inverter for anyone who wants to flexibly store and use their solar power at home. With a rated AC output of 4000 W and backup power functionality, the WIT 4K-HU ensures a reliable energy supply for your home.

Key Benefits for Your System

Reliable backup power supply: In the event of a grid outage, the inverter switches to battery operation in just 10 ms.
High overload capability: Short-term load peaks of up to 200% of rated power for 10 seconds are handled without any issues.
Flexible battery compatibility: Compatible with lead-acid and lithium-ion battery storage in the 40–60 V voltage range.
Easy monitoring: Thanks to integrated Wi-Fi and LAN, you can conveniently keep track of your power consumption via app.

Smart Use of Your Solar Power

A modern hybrid inverter like the Growatt WIT 4K-HU ensures that your self-generated solar power is used optimally – whether for direct consumption, storage in a battery, or grid feed-in. With an efficiency of up to 97.6%, the device operates extremely efficiently and reduces conversion losses to a minimum. The integrated generator input and smart load management enable flexible operation, while the transformerless topology with smart air cooling ensures quiet operation below 50 dB(A). This gives you a significant degree of independence from the public grid and noticeably lowers your electricity costs. Thanks to IP66 protection, the Growatt WIT 4K-HU is also suitable for indoor and outdoor installation.
