Growatt WIT 4-15K-HU Hybrid Inverter

The Growatt WIT 4-15K-HU series consists of advanced three-phase hybrid inverters designed for maximum efficiency, flexibility, and reliability in residential and small commercial installations. This device combines the functions of a grid-tied inverter, battery charger, and uninterruptible power supply (UPS), offering a comprehensive energy management solution. With high input and output currents and smart features, it is ready to work seamlessly with the latest photovoltaic modules and the most demanding loads.

Key Features of Growatt WIT 4-15K-HU:

• High performance and power: A maximum input current per string of up to 20A and a powerful battery charge/discharge current of up to 290A allow full utilization of modern panels and energy storage systems.
• Reliable emergency power (UPS): The inverter supports UPS functionality with a switchover time below 10 ms and a “black start” feature, enabling system startup from batteries without grid access.
• 100% output asymmetry and overload capability: Ability to handle 100% unbalanced load on the output and continuous overload capacity on the AC side at 110% ensures stable power supply even with uneven load distribution across phases.
• Integrated generator input: The inverter includes a dedicated input for an external generator, providing an additional power source and enhancing overall system reliability.
• Intelligent load management: Built-in smart load management functions optimize energy consumption and prioritize power delivery to critical loads.

Who is this the right choice for?

This is an ideal solution for homeowners and small businesses looking for a comprehensive and efficient energy management system. Thanks to its UPS function and generator connection capability, the WIT inverter ensures complete energy security and independence from the public grid. Its capacity to handle high currents and asymmetric loads makes it perfect for modern buildings with multiple loads, such as heat pumps, electric vehicle chargers, or air conditioning systems, guaranteeing stable and uninterrupted power supply.
