Question & Answer
Q&A on the Haier Smart Cube Energy Regulator Three-Phase Hybrid
What is the Haier Smart Cube Energy Regulator Three-Phase Hybrid?
It's a three-phase hybrid inverter with integrated battery management. It converts solar power (DC) into alternating current (AC), feeds it into the grid, or stores it in batteries. Models are available in power classes from 5 kW to 25 kW.
What maximum PV power does the device support?
Depending on the model, the maximum PV input power ranges from 8.000 W (5K) to 40.000 W (25K). All devices are equipped with modern MPPT trackers that optimize solar yield.
Which operating modes are available?
There are four modes:
AI mode for intelligent consumption optimization,
Self-consumption mode for direct use and storage,
Full feed-in mode for maximum grid feed-in,
Time-controlled mode for individual control via app.
How is control and monitoring carried out?
Monitoring is done via LED displays and the Haier Smart Cube app. Additional communication interfaces such as Wi-Fi, RS485, Fast Ethernet, and the KommMod stick are available.
What security and protection features are integrated?
All models feature DC winding fault protection, arc flash protection, reverse polarity protection, insulation and residual current monitoring, as well as AC/DC overvoltage, overcurrent and short circuit protection.
What special features do the devices offer?
Highlights include bidirectional charging (up to 25 kW, V2X-capable), 0 ms backup switching in the event of a power failure, IP66 protection class, intelligent air cooling, heat pump connection, and preparation for dynamic electricity tariffs.
How many MPP trackers are integrated?
Models up to 10 kW have two MPPTs, while models 12 kW and above have three MPPTs integrated. This allows multiple PV strings to be optimized independently, ensuring high yields even in partial shade.
For which applications are the Haier Smart Cube energy regulators suitable?
The smaller models (5-8 kW) are ideal for single-family homes, the medium models (10-15 kW) for large residential buildings or small commercial facilities, and the large models (17-25 kW) for large commercial and industrial applications.
