Description

Growatt WIT 25K-HU is the powerful hybrid inverter for commercial and demanding private photovoltaic systems that require a reliable combination of solar power, battery storage, and backup power supply. With an AC rated output of 25 kW and a three-phase connection, this Growatt hybrid inverter reliably supplies even larger loads with your own energy.

Key Benefits for Your System

High overload capability: 200% overload for 10 seconds easily handles even demanding starting loads.
Reliable backup power supply: The switching time of under 10 ms ensures a nearly uninterrupted power supply.
Flexible scaling: Up to 10 units can be connected in parallel, growing with your energy needs.
Unbalanced load: 100% unbalanced output with up to 50% rated output per phase offers maximum flexibility.

Smart Use of Your Solar Power

The Growatt WIT 25K-HU hybrid inverter makes your photovoltaic system particularly versatile: it efficiently converts the solar power generated, charges the connected battery storage with any surplus, and supplies the stored energy exactly when it's needed. With two MPP trackers and an input current of up to 40 A per tracker, even high-output module arrays can be connected. Through the integrated generator input and intelligent load management, you always keep control of the energy flow. Thanks to RS485, CAN, and WIFI/LAN interfaces, you can conveniently monitor your system via app. This way, you increase your self-consumption, reduce your electricity costs, and gain a significant degree of independence from the public grid.
