The AWS M series wind power generation controller is a sophisticated device designed to integrate MPPT (Maximum Power Point Tracking) control with charge and discharge management for wind turbine systems. This controller is versatile, suitable for grid-tied, off-grid, and grid-tied energy storage systems, with an optional charge function. A key feature is its ability to set the power curve by adjusting wind turbine voltage and current, ensuring the wind turbine consistently operates at its optimal power output. For AWS wind controllers paired with AWS Wind turbines, these settings are conveniently preset, eliminating the need for manual alteration.
Function Description:
The primary function of the AWS M series controller is to efficiently manage power generated by a wind turbine, ensuring it operates at its peak performance through MPPT tracking. It also incorporates comprehensive protection functions to safeguard the system. The controller offers optional solar PV integration, allowing for a hybrid power generation setup. For enhanced monitoring and control, it supports various communication interfaces including RS232, RS485, RJ45, GPRS, Bluetooth, and Zigbee. Models equipped with GPRS, Bluetooth, or RJ45 connections can be monitored via a dedicated app, providing real-time data and remote management capabilities.
The device features an LCD display that, once powered on, enters a browsing status, showing battery voltage. Users can cycle through additional information such as wind turbine voltage, current, power, and charge status by pressing the browse button. The LCD also indicates when the wind turbine is working normally (rotate icon), when brake mode is activated (BRAKE icon), and the charging status (charging icon). A flickering battery icon signifies over-voltage or over-discharge conditions, while a solid battery icon indicates a fully charged state. The dump load indicator light (red) signifies an unload or brake status, turning off when the system operates normally.
