FKJ-B model Product Characteristics
◆The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements.
◆The big screen LCD display. Clearly present the working status of the wind turbine, solar panel, battery and controller.（Wind turbine voltage, current, power display ;solar voltage, current, power display, battery charging current, voltage, charging power, power display.）
◆Two sets of control systems：PWM constant voltage system and three-phase dump load system.
◆PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically start immediately to ensure safe running of the overall wind turbine system.
◆When the battery disconnect or damage, the three-phase dump load will start automatically to avoid the wind turbine idling and runaway accident.
◆When the strong or super-strong wind conditions PWM control to ensure battery charged by the wind turbine with constant voltage and current.
◆The protection function of battery: polarity reverse protection, disconnection and damage protection.
◆Over-charging protection of the battery: When the battery is full (the battery voltage getting 125% of the rated voltage), the controller will carry out three-phase dump load automatically to stop charging the battery.
◆Auto recharging of battery: When the battery voltage reduces to 108% of the rated voltage,it stops three-phase dump load to recharge battery automatically.
◆For the different wind turbine type, the controller can be equipped with mechanical yawing, furled empennage, mechanical or hydraulic, pneumatic, electric magnetic and other brake functions.
◆The inside of the controller is equipped with surge arrester. Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On the other way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.
◆The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
◆ Optional communication Mode：RS232、RS485、GPRS、USB、RJ45 ect, Can monitor multiple devices running.
- Q: What is the maximum power rating a solar controller can handle?
- The maximum power rating a solar controller can handle depends on its specific design and specifications. It can range from a few watts for small-scale systems to several kilowatts for larger installations.
- Q: Can a solar controller be used in a remote location where grid power is not available?
- Yes, a solar controller can be used in a remote location where grid power is not available. Solar controllers are designed to regulate the charging process of batteries using solar panels. They can operate independently from the grid, making them suitable for off-grid locations or areas without access to electricity.
- Q: What is the maximum number of load control modes supported by a solar controller?
- The maximum number of load control modes supported by a solar controller can vary depending on the specific model and manufacturer. However, most solar controllers typically support around 4 to 5 load control modes, allowing users to customize and optimize their energy usage according to their specific needs and preferences.
- Q: What is the role of a solar controller in preventing battery sulfation?
- The role of a solar controller in preventing battery sulfation is to regulate the charging process of the battery and ensure that it is done efficiently and effectively. By monitoring the battery voltage and current, the solar controller can prevent overcharging, which is a major cause of battery sulfation. It also controls the charging rate to avoid undercharging, which can lead to sulfation as well. Overall, the solar controller plays a crucial role in maintaining the optimal charging conditions for the battery, thereby preventing sulfation and prolonging its lifespan.
- Q: Can a solar controller be used in a solar-powered disaster relief system?
- Yes, a solar controller can be used in a solar-powered disaster relief system. A solar controller helps regulate the flow of electricity from the solar panels to the batteries, preventing overcharging and ensuring efficient power storage. This is essential in disaster relief systems where reliable and sustainable energy sources are crucial for powering essential equipment and providing electricity to affected areas.
- Q: Can a solar controller be used with different types of solar panel anti-theft systems?
- Yes, a solar controller can be used with different types of solar panel anti-theft systems. The solar controller's primary function is to regulate the charging of batteries in a solar power system. It does not directly interact with the anti-theft system. The solar panel anti-theft systems are designed to prevent theft or unauthorized access to the solar panels. These systems usually include features like tamper-proof screws, locking mechanisms, alarms, or GPS tracking devices. They are installed separately from the solar controller and are not dependent on its compatibility. The solar controller's main role is to monitor and regulate the flow of electricity from the solar panels to the batteries. It ensures that the batteries are charged efficiently and protects them from overcharging or damage. The type of anti-theft system used does not affect the functionality of the solar controller. Therefore, regardless of the type of anti-theft system implemented, the solar controller can still be used without any issues. It is important to select a solar controller that is compatible with the specific requirements of the solar power system, such as voltage and current ratings, to ensure optimal performance and efficiency.
- Q: Choose a solar controller which need to have a few conditions
- To buy a solar controller must know the power of the solar panel and the load power to be used to determine the controller's charging current and discharge current. General solar controller are 12v / 24v automatic identification. Discharge current = load power / 12v, charge current = battery power / battery board voltage. The voltage of the panel can be set with the multimeter DC. The short-circuit current of the panel uses a clamp meter to test the current. So the battery power = voltage * current, basically know the power of the solar panel. The battery charge current will know. The current range of the controller is greater than the charging current of the solar panel and the discharge current of the load.
- Q: How does a solar controller handle temperature compensation for batteries?
- A solar controller handles temperature compensation for batteries by adjusting the charging voltage based on the battery temperature. As temperature affects the charging efficiency and capacity of batteries, the controller measures the temperature and modifies the charging parameters accordingly to optimize the charging process. This ensures that the batteries are charged at the correct voltage level, preventing overcharging or undercharging, and prolonging their lifespan.
- Q: How does a solar controller prevent damage from power fluctuations?
- A solar controller prevents damage from power fluctuations by regulating and stabilizing the flow of electricity from the solar panels to the battery or grid. It monitors the voltage and current levels and adjusts them accordingly, ensuring that the power supplied remains within safe limits. This prevents overcharging, overheating, and other potential damage that could occur due to unpredictable fluctuations in power output.
- Q: How do I clean and maintain a solar controller?
- To clean and maintain a solar controller, start by turning off the power and disconnecting any external power sources. Use a soft cloth or brush to remove any dust or debris from the surface of the controller. If there are stubborn stains, mix a mild soap solution with water and gently wipe the affected areas. Avoid using abrasive cleaners or solvents. After cleaning, ensure that all connections are secure and free from any corrosion. Regularly check for any loose wires or damaged parts, and replace them if necessary. Finally, keep the solar controller in a dry and well-ventilated area to prevent moisture buildup.
