With high efficiency and low voltage operation, this controller is perfect for optimizing energy production in your renewable energy system.

Overview of the charging processThe process of MPPT controller charging is typically broken down into three phases: rapid charging, maintenance charging, and float charging. By utilizing a combination of boost charging, float charging, equalization charging, and other charging techniques to fully charge the battery, it can significantly prolong the battery's lifespan. The charging profile is illustrated below.An overview of the Maximum Power Point Tracking (MPPT) technologyMPPT technology is a sophisticated system that optimizes the power output of solar panels by regulating the operation of electrical components, taking into account the non-linear characteristics of solar arrays to identify the maximum power point on the array's curve.Conventional solar charge controllers (switch charging technology and PWM charging technology) are not capable of charging batteries efficiently, resulting in a loss of potential energy from solar panels. On the other hand, solar energy charge controllers with MPPT control technology can constantly optimize the power output of a solar array to maximize energy for battery charging. Let's consider a 12V system as an example.Solar panels typically have a peak voltage (Vpp) of around 17V, while the battery voltage is approximately 12V. Normally, during the charging process, a solar charge controller keeps the solar panel voltage at around 12V, which means that the full power potential is not being utilized. MPPT solar charge controllers address this issue by continuously optimizing the input voltage and current of the solar panels to maximize power output.MPPT solar charge controllers, in contrast to traditional PWM solar charge controllers, optimize the power output of solar panels and deliver higher charging currents. In essence, MPPT solar charge controllers can enhance energy efficiency by 15% to 20% compared to PWM solar charge controllers. (Figure 1)In addition, varying environmental temperatures and light conditions result in frequent shifts of the maximum power point. Our MPPT solar charge controller can continuously modify settings based on different conditions to keep the system operating close to its peak efficiency at all times. This entire process is fully automated and requires no user intervention. (Figure 2)Charging system that optimizes wind powerA diagram is provided to illustrate how wind turbine MPPT charging works. The WIND+ and WIND- terminals represent the DC input of the generator post rectification by the controller's internal circuit. BAT+ and BAT- are the terminals for connecting the battery for energy storage.The MPPT power inductor L1 is responsible for storing energy while the MPPT charging process takes place, whereas the reverse isolation protection diode D1 helps minimize losses resulting from switch conduction.A switching MOSFET, known as Q1, is the main element of the MPPT circuit. By utilizing a high-frequency PWM drive waveform, it regulates the MOSFET's functioning to optimize the fan for maximum power operation.In order to respond effectively to the ever-changing wind speed and direction, it is necessary to track and adjust in a timely manner. By analyzing and controlling 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, thus achieving immediate response and realizing the MPPT charging effect.The regular wind turbine charge controller can only charge when the fan is large and the fan voltage is higher than the battery voltage. This product's MPPT controller not only fulfills this condition, but also enables wind charging by boosting the lower fan input voltage through the MPPT boost circuit when the wind is weak and the fan input voltage is lower than the battery voltage, allowing the fan to operate at its maximum power point.Follow the instructions below to complete the wiring steps.External connection for discharging (external discharge connection)Please follow the diagram above to connect the controller and external discharge resistor, without worrying about the order or the positive and negative terminals.Caution: Failure to connect the dump load resistor while the wind turbine is connected could result in harm to the controller.Connect the load to output 2Make sure to follow the diagram above when connecting the controller and the load, ensuring correct polarity. Avoid short circuits and ensure that the load current does not exceed the rated current of the controller.Linking the batteryFollow the diagram above to connect the controller and battery, ensuring the correct order of positive and negative terminals to avoid short circuits.Linking solar panelsMake sure to follow the correct order of connecting the controller and photovoltaic module as illustrated in the diagram, ensuring that the positive and negative terminals are properly aligned. It is strictly forbidden to connect them in reverse.When connecting photovoltaic modules, ensure caution to avoid the risk of electric shock due to high voltages.Linking wind turbinesPlease connect the controller to the wind turbine generator as depicted in the diagram above, without worrying about the order or the polarity of the terminals.Wind turbines can produce high voltages, so be cautious to avoid electric shock when connecting the wiring. It is advisable to connect the fan when there is no wind or breeze. Fans that spin at high speeds should be connected after the controller has been activated.Surgical procedureExplanation of button functionsOnce the controller is turned on, you will be directed to the default LCD parameter browsing interface, as illustrated in the figure below.Explaining the functions of the buttonsInstructions for setting parameters and operating procedures
