This wind turbine controller is specially designed for small wind and light hybrid system, which can simultaneously control the wind turbine and solar panel to charge the battery safely and efficiently, and at the same time, it has the functions of wind turbine overspeed protection and battery overcharge protection. It has a PWM design wide frequency dump load function, which helps to extend the service life of the wind turbine. Not only that, it is also equipped with wind turbine automatic and manual dual braking function, as well as as data communication function as an optional, TTL232 or RS485 communication method can be selected. The hard shell ensures its durability, and the limit can be operated in -40~+60℃ environment with protection class IP41.
Q1. What is dump load and what is its role in 3000W wind turbine controller?
When the wind is too strong or the generator is under light or no load, the output voltage may exceed the safe range. At this time, the dump load will automatically put into work to increase the load of the generator to reduce its speed and protect the equipment from damage. Read What is a Dump Load for Wind Turbine Controller? for more details.
Q2. What is PWM stepless high-frequency dumping?
PWM stepless high-frequency dumping is an advanced dumping technology that reduces or removes wind turbine loads smoothly and continuously by adjusting the frequency and duty cycle of the PWM signal. Advantages of this technology include fine load control, improved dynamic response and stability of the system, reduction of shocks and mechanical stresses on the grid, and extended equipment life.
