Haier Hybrid Inverter 12 kW, 3-phase HAH3P-12KB1/HU9

The Haier 3-phase hybrid inverter (MPN: HAH3P-12KB1/HU9) has a power output of 12 kW and is the heart of your flexible home energy storage solution. Combined with the matching battery modules and a maximum capacity of 28.8 kWh, it helps you become less dependent on rising electricity prices and grid fluctuations. The intelligent energy management system ensures that your self-generated electricity is used optimally. In the event of a power outage, the inverter takes over the backup supply in a flash—in less than 10 milliseconds. Additionally, the system supports maximizing self-consumption and utilizing dynamic electricity rates, and can be easily expanded with additional features.

• Performance: Optimization of energy consumption and maximum efficiency of your system
• Flexible installation: Choose between wall or floor mounting, indoors or outdoors
• Warranty: 10-year manufacturer’s warranty; find more information here

How it works

The hybrid inverter is a high-performance, three-phase device that efficiently converts the direct current generated by solar modules into grid-compliant alternating current and intelligently manages the energy flows between the photovoltaic system, battery storage, power grid, and consumers. Excess solar energy is primarily used for self-consumption, then stored in a compatible battery, and only subsequently fed into the public grid. When needed—for example, at night or during periods of increased electricity consumption—the inverter reliably provides the stored energy. Optionally, it enables an uninterruptible emergency power supply in the event of a grid outage. With its high efficiency, flexible battery management, comprehensive protection functions, and modern communication interfaces, it offers an efficient and future-proof solution for the intelligent use and control of solar power in residential and commercial buildings.

Arc Fault Circuit Interrupter (AFCI)

If your PV modules, connectors, or cables are improperly installed or damaged, so-called arcs can occur, which may cause fires. To quickly prevent such fires, Haier has developed an optional arc fault detection system. This feature is installed and ensures a higher level of safety for you and your PV system.

Three MPP trackers for optimal solar yields

Maximum Power Point Tracking (MPPT) technology ensures your solar system generates the best possible yield. Throughout the day, the MPPT determines the optimal balance between irradiance, module temperature, and solar cell type. Thanks to the three trackers, the optimal operating point for the two PV strings can be optimized separately. They operate independently of one another, so, for example, shading on one string would not affect the second or third.
