Inverter GROWATT WIT 15K-HU

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 with the latest photovoltaic modules and the most demanding loads.

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

• High efficiency and power: A maximum input current per string of up to 20A and a powerful battery charging/discharging current of up to 290A allow for full use of the potential of modern panels and energy storage systems.
• Reliable emergency power supply (UPS): The inverter supports a UPS function with a switching time below 10 ms and a “black start” capability, enabling the system to start from batteries without grid access.
• 100% output imbalance tolerance and overload capability: The ability to handle 100% unbalanced loads on the output and continuous AC-side overload capacity of 110% ensures stable power 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 increasing the overall system’s reliability.
• Smart load management: Built-in intelligent load management features optimize energy consumption and prioritize powering key devices.

Who is this a good choice for?

This is an ideal solution for homeowners and small business owners seeking a comprehensive and efficient energy management system. Thanks to the UPS function and the option to connect a generator, the WIT inverter guarantees full energy security and independence from the public grid. Its ability to handle high currents and asymmetric loads makes it perfect for modern buildings with multiple devices such as heat pumps, electric vehicle chargers, and air conditioning systems, ensuring stable and uninterrupted power supply.
