Dump Load MPPT Wind Charge Controller 12V 24V 600W 800W For Charge Battery Energy Storage

Both solar and wind power are wonderful green energy sources that cannot be exhausted. While they may be inconsistent due to their nature, they can not only allow individuals to live off the grid, but also provide energy to rural areas that previously had no electricity. Both sources have pros and cons. Solar panels require much less space than wind turbines and can be installed on the roofs of buildings. They also require less maintenance. Wind turbines can harness electricity during the day or night, effectively producing more electricity than solar panels. Newer small wind turbines are also entering the market for small-scale use. Another big difference between them is how they use power.

Wind charge controllers can also be PWM or MPPT controllers, which work the same way, with the same pros and cons. The difference is in connecting additional components into the system. If the turbine is connected to the grid, there is not necessarily other electrical equipment or load shedding in the system. The charge controller will simply transfer the load to the grid. An obvious problem is that during a power outage, the wind turbines also need to be shut down because the excess power has nowhere to go. Therefore, it might be a good idea to connect offloading equipment, as in an off-grid wind energy system. Therefore, excess power can be fed to the grid or to an unloading device, usually a fan, heater or special resistor.

Functions and Features
BOOST and BUCK function in one 
(If do not buy Boost & Buck Wind Solar 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.

BOOST function 
(If do not buy Boost Wind Solar Controller, there is no this function)
Once wind generator voltage is lower than battery voltage, controller starts boost module automatically to charge to battery.

BUCK function 
(If do not buy Buck Wind Solar Controller, there is no this function)
Once wind generator voltage is higher than battery voltage, controller starts buck module automatically to charge to battery.

Protect wind generator from over-current and speed

Once the wind current is over the setting max current and speed,PWM intelligent dumping will start automatically. That protect wind generator. > Intelligent limiting of batteries max current wind generator external dump load resistance

Battery Temperature Compensation Function

(This function is alternative)

RS232 or RS485 interface (This function needs additional payment)
By RS232 or RS485 serial interface communication, you could monitor the whole system, storage and analyze data. Program could be upgraded by serial interface. Connect PC and controller by serial interface. You could set the parameters on PC and controller simultaneously. Software is free,easy to operate and no need to be installed.

Q and A

Q1:Can MPPT be used for wind turbines?

A1: Solar charge controllers cannot be used for wind turbines, although both energy sources use the same type of controller, PWM and MPPT.

Q2: What is MPPT Wind Charge Controller?

A2:  The wind MPPT controller charger is specially designed for wind turbines with power less than 1000W. MPPT charging enables the wind turbine to charge the battery even at low wind and rotor speeds, while at the same time Increase the utilization rate of wind power by 10%-15%.

Q3: What is a charge controller for a wind turbine?

A3:  A wind charge controller is an electronic device that both ensures that the turbine does not overcharge the battery and also limits the speed at which the wind turbine blades can spin when the battery is full or in high winds.
