Frequently Asked Questions
What standards are used to manufacture the FKJ-MPPT off-grid wind-solar hybrid controller?
The controller is manufactured according to the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard. It can also be customized based on users' specific technical requirements.
What real-time parameters can be viewed on the LCD display?
The big LCD display shows wind turbine voltage, current, and power; solar panel voltage, current, and power; and battery voltage, charging current, and charge power.
What safety and protection features does the controller have?
It features comprehensive protections including battery anti-reverse connection, battery anti-disconnection, battery anti-damage, overcharge protection, over-voltage protection, over-current protection, lightning protection, and manual brake control.
Does the system support remote monitoring and communication?
Yes, it adopts the Modbus communication protocol and allows adjustment of specifications via RS485. It supports WIFI, GPRS, and Ethernet connection to monitor real-time data through a PC or mobile terminal (compatible with Android and iOS).
Can this controller support additional braking or tail controls for wind turbines?
Yes, depending on the wind turbine type, the controller can add yaw control, rotor control, mechanical tail control, mechanical brake, hydraulic brake, electromagnetic brake, and other brake control functions.
What are the main application areas of this controller?
It is widely used in remote areas without electricity (islands, border posts), transportation (navigation, traffic signals, street lights), communications (unattended relay stations), wind-solar hybrid power stations, and government projects.
