Wind Turbine and Load Adaptive Impedance Matching, maximize energy utilization.
There is internal resistance in Wind generators, batteries and loads. According to impedance matching principle, only when input impedance equals to output impedance, power utilization is maximal, get the maximum power.
Protect wind generator from over-revolution speed, over-voltage and over-current
Max revolution speed, max voltage and max current of wind generator could be set. Once the actual revolution speed, voltage or current over the set ones, PWM intelligent unloading will start automatically. That protect wind generator.
Intelligent limiting of batteries max current
Batteries maximum capacity could be set through this controller. According to the set maximum capacity, controller could calculate the maximum charging current. Then batteries will be protected.
Two DC output, each one has 9 output modes
Function of manual brake
Wind charging manual switch
On the controller you can manually set whether using wind charge to battery.
Solar charging manual switch
On the controller you can manually set whether using solar charge to battery.
DC output manual switch
Users could manually set whether use DC output.
BOOST and BUCK function in one
(If do not buy Boost & Buck Wind Solar Streetlight Controller, there is no this function)
Once wind generator voltage is lower than battery voltage, controller starts boost module automatically. Wind generator voltage is increased to the charging voltage, and it is boost charging. When wind generator voltage is higher than battery voltage, in order to acquire max power, buck module of controller will be started, the generator is buck charging.
Loads lower the revolution speed of wind generator, when it is breeze. That decreases the output power of wind generator. Through max current tracking (MCT) and max power point tracking (MPPT), output of wind generator is stabilized at the max balance of wind energy utilization. Combine with boost and buck function, wind energy utilization is increased.
(If do not buy Boost Wind Solar Streetlight Controller, there is no this function)
Once wind generator voltage is lower than battery voltage, controller starts boost module automatically to charge to battery.
(If do not buy Buck Wind Solar Streetlight Controller, there is no this function)
Once wind generator voltage is higher than battery voltage, controller starts buck module automatically to charge to battery.
