Small Vertical Axis Wind Turbine Generator for home use off-grid system

BF-H Series 5kW Vertical Axis Wind Turbine

Our BF-H series wind power generating system features advanced vertical axis technology with magnetic suspension structure, delivering exceptional wind energy efficiency and reliable performance for residential and small business applications.

Key Features

High wind energy coefficient with low startup wind speed (3.2m/s)
Superior anti-wind capability and stable operation
Noise-free performance with maintenance-free design
Advanced anti-corrosion treatment and sealing for long service life
Captures wind from any direction without yaw mechanism
Ideal for urban and suburban environments with turbulent wind flows

Generator Body

Features high-grade Neodymium Iron Boron permanent magnets, each tested for magnetic flux by authorized institutions. Engineered for low starting torque while maintaining high generating efficiency through optimized internal structure.

Wind turbine generator internal components

Blade Specifications

Streamline shape with 3 reinforced fiber plastic blades. Manufactured using unidirectional fiber fabric and epoxy resin molds with inner foam core construction. Designed for low noise operation, excellent balance, and superior fatigue resistance.

Wheel Hub & Connectors

Precision-made steel wheel hub connects blades to generator. Blades connectors constructed from Q235 plate with anti-corrosion surface treatment for durable performance.

Tower Options

Available in Q235 guy wire tower with anti-corrosion painting or free stand tower with hot dip galvanized plastic spraying for various installation requirements.

Off-grid Controller

Wind-solar hybrid controller which rectifies AC current generated by wind generator into DC current and charges the battery bank. Unload function activates when strong wind produces excess current. The controller brakes when batteries reach full capacity (125% voltage) and resumes charging when voltage reduces to 108%. Includes manual brake button for emergency stops.
