The On grid wind turbine system is composed of wind turbine, on grid controller, on grid inverter, metering device, and power distribution system. Wind energy is converted into AC electrical energy by the wind turbine, and then converted into DC electrical energy by the on grid controller, and then DC electrical energy is converted into AC electrical energy of the same frequency and phase as the grid by the on grid inverter, and part of the power is supplied to the local load. Surplus power is fed into the grid.

• 1 Produced according to the industry standard JB/T6939.1-2004 and national standard GB/T19115.1-2003, customizable to user technical requirements.
• 2 Color touch screen display visually shows the controller's working status. Rich data display includes real-time wind turbine voltage/current, solar panel voltage/current, DC output voltage/current, and cumulative power generation.
• 3 Technical parameters and control settings can be adjusted directly through the touch screen for compatibility with different wind turbines.
• 4 Equipped with two dual-control safety systems: PWM constant voltage/constant current system paired with a three-phase braking system.
• 5 Supports additional current control, wind speed control, and wind turbine speed control with adjustable parameters.
• 6 Under strong wind conditions, the controller delivers constant voltage and constant current DC output to guarantee the stable operation of the inverter.
• 7 When the on-grid inverter goes offline, the controller maintains a constant voltage output and waits for the inverter to resume operation.
• 8 When grid failure occurs, the controller auto-activates the wind turbine brake, halting inverter output. Once the grid recovers, the brake is released, resuming power supply.
• 9 Internal surge protection handles over-voltage spikes, safely directing lightning currents to the ground to protect the equipment.
• 10 Features an front-panel emergency stop switch to cut off all power output and immediately engage the wind turbine brake.
• 11 Equipped with a manual brake switch for user-controlled system deceleration and maintenance safety.
• 12 Adopts Modbus communication protocol, facilitating convenient secondary development for system integrators.
• 13 Supports RS485, WiFi, GPRS, and Ethernet connections. Real-time and historical system monitoring is fully accessible via PC or mobile apps (iOS & Android) with IoT compatibility.
• 14 Optional solar panel control system can be integrated based on specific project needs.
• 15 Can be upgraded with auxiliary systems: yaw control, pitch control, mechanical folding tail, hydraulic brakes, and electromagnetic brakes.
