Five, generator common problems
1. The customer does not know much about the use and scope of the wind-solar hybrid generator. We should give a detailed understanding of the load and resources used by the customer when making application suggestions to the customer.
2. Some customers are very concerned about the wind speed of the wind turbine. In this respect, compared with the fan of other companies, when the wind is taken at 1.5m2 (400W), for example, at 3m/sr wind speed, the energy generated can be too Small, meaningless. Therefore, wind power generation below 3M has no use value, and there is a change in cost (increased blade length).
3. Why does 600W not do the 12V standard?
The battery needs 30V, and the wire needs to be thickened, and the cost is increased.
4. Is the vibration of the HY series fan very strong?
We design the resonant frequency to very low speed, HY and other components die-casting or injection molding, other fans are generally manual, in contrast, the fins run more smoothly. Therefore, our street lamps do not pull steel wire and no vibration is generated.
5. Which efficiency is higher compared to solar energy?
The conversion efficiency of wind turbines is high, but it is greatly affected by the environment. The power ratio of wind-solar complementary wind power generation to solar power generation is 3:1.
6. The solar panels we use together.
The difference between polysilicon and monocrystalline silicon solar panels: we use polysilicon, the raw material is imported from Japan Sharp, the manufacturer is Shanghai Solar Co., Ltd.
7. What generator is used by the fan?
The generator we use is a permanent magnet generator (NdFeB permanent magnet power generation), and the other is an excitation generator. The excitation generator is generally used on a large fan.
8. Inverter
Due to the different inverter voltages and systems used in each location, it is generally recommended that rooms be purchased locally. Such as the United Kingdom 230V, Japan 110V, the domestic is 220V square wave output (poor efficiency, easy to be electromagnetic interference)
