Charging stage introduction

Controller MPPT charging is usually divided into three stages: fast charging, maintenance charging, and float charging. By combining lifting charging, float charging, equalizing charging and other charging methods to complete the charging of the battery, it can effectively extend the service life of the battery. The charging curve is as follows:

Introduction of the MPPT

The Maximum Power Point Tracking (MPPT) system is an advanced charging technology that enables solar panels to output more power by adjusting the working state of electrical modules. Due to the non-linearity of a solar array,there is a maximum energy output point (maximum power point) on the curve of the array. Traditional solar charge controllers (switch charging technology and PWM charging technology) cannot charge batteries at this point, thus unable to obtain the maximum energy of solar panels. However, the solar energy charge controller equipped with the MPPT control technology can track the maximum power point of a solar array at any time in order to gain maximum energy for battery charging.Take the 12V system for example. The peak voltage of solar panels (Vpp) is around 17V and battery voltage is about 12V. Generally, when the solar charge controller is charging a battery, the voltage of solar panel is maintained at about 12V, indicating that the maximum power is not used. MPPT solar charge controllers provide a solution to that problem by constantly adjusting the input voltage and current of solar panels, therefore maximizing input power.

Compared with conventional PWM solar charge controllers, MPPT solar charge controllers bring out the maximum power of solar panels and provide greater charging current. Generally speaking, MPPT solar charge controllers can improve energy utilization rate by 15% ~ 20% over PWM solar charge controllers.(Figure 1)

Moreover, different environmental temperatures and light conditions lead to frequent changes of the maximum power point. Our MPPT solar charge controller can constantly adjust parameters according to different conditions so as to put the system near the maximum working point all the time. The whole process is completely automatic without any adjustment by users.(Figure 2)

Wind MPPT-boost charge

The figure is a schematic diagram of the principle of wind turbine MPPT charging. WIND+and WIND – are the DC input terminals of the generator after being rectified by the internal rectifier circuit of the controller. BAT+and BAT – are battery energy storage connection terminals.

L1 is the MPPT power inductor, which is used to store energy during the MPPT charging process. D1 is a reverse isolation protection diode that can reduce the loss caused by the conduction of the switch.

Q1 is a switching MOSFET, which is the core component of the MPPT circuit. It controls the operation of the MOSFET through a high-frequency PWM drive waveform, thereby adjusting the fan to the maximum power operation state.

Due to the constant changes in the wind speed and direction of the natural wind, timely tracking and adjustment are required. According to the generator input signal sampled by the controller, the circuit adjusts the driving waveform of MOS tube Q1 in real time through MCU analysis and control and MPPT software algorithm, thereby achieving instant response and achieving MPPT charging effect.

The ordinary wind turbine charging controller can only be charged when the fan is large and the fan voltage is higher than the battery voltage. The MPPT controller of this product can not only meet this requirement, but also realize the breeze charging function by boosting the lower fan input voltage through the MPPT boost circuit when the wind force is low and the fan input voltage is lower than the battery voltage, and allowing the fan to operate at the maximum power point.

Wiring Steps（Follow the bellow suggestions and steps to connect)

1.Dump load connection（external dump load）

（Connect the controller and external unloading resistor as shown in the above figure, regardless of sequence and positive and negative electrodes）

Note: If the dump load resistor is not connected and the wind turbine is connected, it may cause damage to the controller.

2.Output load connection

（Connect the controller and the load as shown in the above figure, paying attention to the positive and negative , and it is strictly prohibited to have a short circuit or the load current exceeding the rated load current of the controller）

3.Battery connection

（Connect the controller and battery as shown in the above figure, paying attention to the sequence of positive and negative electrodes, no short circuits）

4.Solar panel connection

（Connect the controller and photovoltaic module as shown in the above figure, paying attention to the sequence of positive and negative electrodes, and reverse connection is strictly prohibited）

Photovoltaic modules may generate high voltages, so be careful to prevent electric shock when wiring

5.Wind turbine connection

（Connect the controller to the wind turbine generator as shown in the above figure, regardless of the sequence and the positive and negative electrodes）

·Wind turbines may generate high voltages, so be careful to prevent electric shock when wiring
·It is recommended to connect the fan when there is no wind or breeze. Fans that rotate at high speed must be connected after the controller is started
