Product introduction
This kind of wind-solar hybrid charge controller is specially designed for small off-grid wind
Generation and solar hybrid system. Appearance is elegant, operations are simple. It also makes the
Expiration, in which wind generator and solar panels charge batteries safely and efficiently.
Functions and Features
Wind generator MPPT boost charging function, improved charging efficiency . External dump load resistant to strong wind, work more stable. Solar MPPT charging, solar intelligent separation charging, high efficiency charging. Bluetooth function can display the system information through the app on the app on the Phone(Only for Android). Dual power supply function: battery and solar power supply. LCD shows parameters such as voltage and current of wind, solar and load .
Some parameters can be set by users. DC output with three output modes. Battery module type can be selected and parameters can be set;The controller has a built-in dust net that is easy to replace and clean to ensure the service life of the controller. The inner circuit board of the controller is sprayed with conformal coating to prevent
Prevent dust, moisture and static electricity
Solar energy protection:As in the night, the voltage of the battery can be higher than the solar panel. Thecontroller protects the battery from charging the solar panel.
Battery protection: if the battery polarity is reversed, the controller will not work and there will be no display. The fuse protects the internal circuit. If the battery does not work properly after it is connected properly, you only need to replace the fuse.
Battery open circuit protection: after long time use, the battery may be open circuit or bad connection. The controller can protect itself from damage. Check the connection regularly
Over-voltage Over-current Over-voltage: When it is strong wind or over-voltage, the controller will automatically start the braking function to protect the wind generator and the battery. The controller will automatically break the circuit when the output is overvoltage.
Lightning Protection: Lightning protection refers to the last level of protection required for equipment.
Special lightning protection devices and other components of the multi-level lightning protection system are required for lightning-prone areas. If the user requires this function, it must be paid additionally.
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 operating state of electrical modules. Because of
the nonlinearity of a solar array,there is a maximum energy output point (maximum power point) on the
curve of the array. Traditional solar charge controller (switch charge technology and PWM charge)
Technology) can not charge batteries at this point, therefore, unable to obtain the maximum energy of solar energy
Plates. However, the solar charge controller equipped with MPPT control technology can.
Track the maximum power point of a solar system at any time to obtain maximum energy for battery
Charge. Take the 12V system for example. The peak voltage of solar panels (Vpp) is about 17V and
Battery voltage is about 12V. In general, when the solar charge controller charges a battery.
Solar panel voltage is maintained at about 12V, which means the maximum power is not consumed.
MPPT solar charge controllers provide a solution to this problem by constantly adjusting the input
Voltage and current of solar panels, maximizing the input power.
Compared to traditional PWM solar charge controllers, MPPT solar charge controllers bring you
Utilize the maximum power of solar modules and provide higher charging current. In general:
MPPT solar charge controllers can improve the energy utilization rate by 15% ~ 20% compared with PWM solar
Charge Controllers.
In addition, different ambient temperature and lighting conditions will cause frequent changes in the
the maximum power point. Our MPPT solar charge controller can adjust parameters constantly
According to different conditions to constantly place the system near the maximum operating point.
The whole process is fully automatic without any adjustment by the user.
The figure is a schematic diagram of the principle of MPPT charging of the wind turbine.
WIND+and WIND input terminals are the DC input terminals of the generator after rectification by the internal rectifier circuit
of the controller. BAT+and BAT: are battery storage connection terminals.
L1 is the MPPT power inductor used to store energy during MPPT charging.
D1 is a reverse isolation protection diode that can reduce the loss caused by the line of the Switch.
Q1 is a switching MOSFET, which is the core component of the MPPT circuit. It controls the
operation of the MOSFET via a high-frequency PWM drive waveform, which causes the fan to operate at
Maximum Power Operating Condition.
Due to the constant changes in 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 drive waveform of MOS tube Q1 in real time by MCU analysis and control
and MPPT software algorithm, achieving instantaneous response and MPPT charging effect.
The ordinary charge controller of the wind turbine 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 increasing the lower fan input voltage
through the MPPT boost circuit when the wind power is low and the fan input voltage is lower than the
Battery voltage and allow the fan to operate at the maximum power point.
