Product Description:

Off-Grid PWM Wind Solar Hybrid Controller2KW

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 meaning of the DC load above the solar controller?
Solar power systems are generally DC storage, of course, there are grid-connected power generation, the output is AC, but this system is still relatively small in the country, especially for some small systems. If it is a solar street light system,
Q:The principle of solar controller
Solar controller uses high-speed CPU microprocessor and high-precision A / D analog-to-digital converter, is a computer data acquisition and monitoring and control system. It can collect the working data of the PV station in real time, obtain the working information of the PV station at any time, and accumulate the historical data of the PV station in detail, and provide the accurate and reliable evaluation of the reliability of the PV system design and the reliability of the quality of the inspection system Full basis. In addition, the solar controller also has a serial communication data transmission function, can be a number of photovoltaic systems sub-station for centralized management and remote control.

Re-adjust the water level to control, choose their own water.
Q:What is the use of solar controller
Power adjustment function
Q:Solar controller one machine how
4LED display status, dual digital display mode of operation (a key operation intuitive, with power saving mode); can also be compatible with 12V system and 24V system (fully compatible) LED lamp operating current size, that is, the first period of work adjustable power ; The second time period, the third time period the power size adjustable, adjustable range of 10% -90%; the first time period, the second time period, the third time period, before dawn lights time adjustable; Tune, that is, after a few days after the delay in time to turn on the lights.
Q:What is the meaning of the 30A solar controller?
The maximum current is 30A
Q:How does the solar controller set up Sheung Shui?
Solar water, heating is fully automatic operation, so users do not have to do any operation. The user can use the "SET" key to adjust the Beijing time and all-weather timing Sheung Shui, regular heating time, use ← left shift, right shift key to select the adjustment items, use ↑ to rise, ↓ down key to adjust the parameters, press "SET" Sheung Shui, heating, heat preservation, cycle key can start the corresponding function, after starting, Sheung Shui, heating, insulation, cycle icon flashing. The user continues to hold down the "SET" key to restore all parameters of the all-weather mode set by the factory.
Q:A solar controller 12v20A battery 12v 20A Will the need for a few watts of solar panels can be normal charge
Solar controller is called solar charge and discharge controller, is used in solar power system, the control of multi-channel solar cell battery charging and battery to the solar inverter load power supply automatic control equipment.
