Haier Smart Cube HH3P-25K 25kW hybrid inverter - 3-phase energy controller

The Haier Energy Controller (MPN: HH3P-25K) is a 3-phase hybrid inverter with an output power of 25kW. It has 4 MPP trackers, works with a maximum PV power of 40000W and is the heart of the Smart Cube system. It seamlessly converts direct current (DC) from your PV modules into alternating current (AC). It can therefore take the electricity generated by your solar system and feed it into the power grid or store it in your batteries. The wireless mounting of the components makes installation much easier. In conjunction with the integrated battery management system, it sets new standards in terms of efficiency and intelligence. It is therefore a first-class solution for the use of solar energy in residential and commercial buildings.

Different modes with the Smart Cube

AI mode - By analyzing your consumption patterns and local electricity prices over a certain period of time, the integrated AI can develop tailor-made electricity solutions for you. So you can maximize your savings.
Self-consumption mode - When the sun is shining, your PV system supplies your appliances first. surpluses are stored in the battery and fed into the grid. When there is a lack of sunshine or in the evening, the batteries supply you with the electricity generated.
Full feed-in mode - During the day, the surplus electricity is stored if the PV system produces more energy than the inverter can process. At night and when there is little sun, the batteries supply the stored electricity so that the inverter delivers full power.
Time-controlled mode - Here you can set charging and discharging times in the Haier Smart Cube app. During the day, surplus electricity is sold to the grid or stored. At night, when electricity prices are low, the batteries are charged from the grid to save costs.

monitoring and protection

• DC winding fault protection
• Arc fault protection
• DC reverse polarity protection
• Insulation monitoring
• Residual current monitoring
• DC/AC overvoltage protection type II
• Islanding protection
• AC overcurrent protection
• AC overvoltage protection
• AC short-circuit protection

Display options

The inverter can display many different messages via an LED status display. The controller lights up in different colors and flashes for each of the 5 symbols. So you get information about the energy storage, DC, signal, AC and DC charger display. You will find further information in the user manual, which explains everything in detail.

Four MPP trackers for optimum solar yields

Maximum Power Point Tracker technology generates the best possible yield from your solar system. The MPPT determines the optimum ratio between irradiance, module temperature and solar cell type over the course of the day. The four trackers allow the optimum operating point for the PV strings to be optimized separately from each other. They work independently of each other and so, for example, shading on one string would have no effect on the others.
