Description

Growatt WIT 20K-HU is the powerful three-phase hybrid inverter for demanding solar systems in commercial and residential applications. With a rated power of 20 kW and a maximum recommended PV power of 40,000 W, this inverter offers ample headroom to efficiently convert your solar power and sustainably lower your energy costs.

Key Benefits for Your System

Reliable backup power: In the event of a grid outage, the Growatt WIT 20K-HU switches to backup mode in under 10 ms, keeping your essential loads powered.
High scalability: Up to 10 units can be connected in parallel, allowing your system to grow along with your needs.
Flexible loads: Thanks to 100% unbalanced output and 200% overload capability for 10 seconds, the inverter handles even demanding startup currents.
High efficiency: With a maximum efficiency of 97.6%, you get the most out of your photovoltaic system.

Smart Use of Your Solar Power

A modern hybrid inverter ensures your solar power is optimally distributed between self-consumption, battery storage, and the grid. The Growatt WIT 20K-HU features two MPP trackers with a wide operating voltage range of 150 to 850 V, allowing flexible connection of different module strings. With a maximum charge/discharge current of 420 A, it efficiently integrates your battery storage and delivers stored energy exactly when you need it. The integrated generator input and smart load management further expand your options. This gives you a significant degree of independence from the public grid and lets you continue operating your photovoltaic system safely even during grid outages.
