The power and usage range are different.
1. Power is different. A 2 kW parking generator is less powerful, while a 5 kW parking generator is more powerful.
2. The scope of use is different. The 2 kW parking generator is suitable for small area power supply, while the 5 kW parking generator is suitable for large-scale power supply.
It would be very difficult for you to make it by hand, but it is truly a unique gift. I can only explain its principle to you now. The principle of a hydroelectric generator is a bit like that of the ancients. water generators. In car, it uses the water flow to impact the wheel and rotate it, causing the rotor connected to the wheel to rotate through the bearing.
Then the electromotive force is generated in the coil of the generator thanks to the principle of electro inductionthat. I hope this will be useful to you. I'm afraid you'll get dizzy from the details, so I won't go into detail. But the most important thing is that. there must be an excitation coil inside the generator. It's very disturbing. It is better to buy a generator, turbine and other things and make them yourself.< /p>
