Description

Growatt WIT 15K-HU is a powerful three-phase hybrid inverter for demanding residential and commercial systems that want to flexibly store their solar power and remain self-sufficient in an emergency. With a rated power of 15,000 W (15 kW), this Growatt inverter reliably supplies even larger loads.

Key Benefits for Your System

High power: 15 kW rated power and up to 24,000 W recommended PV power provide ample reserves.
Reliable backup power: In the event of a grid outage, the system switches to backup mode within just 10 ms.
Robust overload capability: 200% overload capacity for 10 seconds can start even demanding loads.
Flexibly expandable: Up to 6 units can be connected in parallel – ideal for growing systems.

Intelligent Use of Your Solar Power

The Growatt WIT 15K-HU hybrid inverter connects your photovoltaic modules, battery storage, and household grid into an intelligent energy system. Thanks to the integrated generator input and smart load management, you use your solar power exactly when it is needed and store surpluses for the evening and night hours. With a maximum charge and discharge current of 290 A, high storage output is also possible. The 100% unbalanced output power allows each phase to be loaded individually up to 50% of the rated power. This gives you a large degree of independence from the public grid, lowers your electricity costs, and ensures you are well supplied even during a power outage. Monitoring is conveniently done via WiFi/LAN and app.
