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: Can a solar controller be used in a solar-powered cooling system?
- Yes, a solar controller can be used in a solar-powered cooling system. A solar controller helps regulate the flow of electricity between the solar panels and the cooling system, ensuring efficient operation and protecting the system from overcharging or damage.
- Q: Do solar controllers require regular maintenance?
- Regular maintenance is required for solar controllers. Although they are built to be durable and reliable, it is necessary to perform regular maintenance to ensure optimal performance and longevity. Some common maintenance tasks include cleaning the solar panels to remove dirt or debris that could reduce efficiency, inspecting the wiring and connections for damage or corrosion, and checking the controller's display and settings to ensure proper functioning. It is also recommended to periodically test the system's battery voltage and charge controller settings to ensure they are operating within desired parameters. Regular maintenance not only helps identify potential issues early on but also maximizes the efficiency and lifespan of the solar controller.
- Q: What is the operating temperature range of a solar controller?
- The operating temperature range of a solar controller typically falls between -40 degrees Celsius to 85 degrees Celsius.
- Q: What are the key features to consider when purchasing a solar controller?
- When purchasing a solar controller, some key features to consider include the controller's maximum voltage and current capacity, as it should be able to handle the power generated by your solar panels. Additionally, the controller should have a suitable charging algorithm to optimize battery charging and prevent overcharging. Other important features include temperature compensation to ensure efficient performance in varying weather conditions, display and monitoring options for easy operation and system troubleshooting, as well as built-in protection mechanisms like reverse polarity and short circuit protection. Ultimately, the choice should also depend on the specific requirements of your solar power system.
- Q: What is the maximum voltage and current that a solar controller can handle?
- The maximum voltage and current that a solar controller can handle depend on its specifications and capacity. Different models and brands may have different limits. It is important to check the manufacturer's specifications or consult the product manual to determine the specific maximum voltage and current ratings for a particular solar controller.
- Q: What is the purpose of a solar controller in a solar power system?
- The purpose of a solar controller in a solar power system is to regulate and control the flow of electricity between the solar panels and the batteries. It ensures that the batteries are charged efficiently and prevents overcharging, which can damage the batteries. Additionally, the solar controller also protects the batteries from discharging too much during periods of low sunlight, extending their lifespan.
- Q: Can a solar controller be used with solar panels that are connected in series?
- When solar panels are connected in series, it is possible to use a solar controller. In fact, it is often advised to use a solar controller in such cases, as it helps regulate the voltage and prevents the batteries from being overcharged. Acting as an intermediary between the panels and the batteries, the solar controller ensures that the batteries receive the ideal charge and safeguards them from potential damage caused by excessive voltage. By monitoring the voltage and current from the solar panels, the solar controller can adjust the charging parameters to optimize the efficiency and lifespan of the batteries. Hence, it is highly recommended to use a solar controller when connecting solar panels in series to guarantee the proper functioning and longevity of the entire solar power system.
- Q: Can a solar controller be used with solar-powered indoor heating systems?
- Yes, a solar controller can be used with solar-powered indoor heating systems. The solar controller helps regulate and optimize the flow of solar energy to the heating system, ensuring efficient operation and maximizing energy usage.
- Q: How do you protect a solar controller from lightning strikes?
- One effective way to protect a solar controller from lightning strikes is by installing a surge protection device (SPD) at the point where the solar panels connect to the controller. This SPD helps to divert the electrical surge caused by lightning strikes away from the controller, ensuring its safety. Additionally, grounding the entire solar system and using proper lightning rods or conductors can further minimize the risk of damage from lightning strikes. It is essential to consult with a professional electrician or a solar installer to ensure proper installation and protection measures are in place.
- Q: Can a solar controller handle high voltage surges?
- Yes, a solar controller is designed to handle high voltage surges. It has built-in protective mechanisms such as surge protection devices and voltage regulation circuits to safeguard the system from voltage surges caused by lightning strikes or other electrical disturbances.
