Leading technology-intelligent control, strong system scalability
1. The world's best wind power control technology is combined with the self-developed variable pitch technology.
2. The hardware design uses international well-known brands, and the software uses redundant control strategies.
3. It can achieve good compatibility with various well-known brand converters and remote modules.
High security-continuous operation around the clock to achieve unattended operation
1. The speed of the wind wheel is controlled, and it runs continuously and stably under severe wind conditions.
2. More than a dozen redundant control strategies ensure the safety and stability of the system in all climates.
A lot of power generation-variable pitch control, high-efficiency output, power generation up to 30%
1. Above the rated wind speed, the pitch angle of the blades can be adjusted to achieve continuous full power output.
2. The working wind speed range is large (3-25m/s), and the effective running time is long.
This canal flows day and night – I never thought it could make money. After Greef installed the system, it runs by itself. Every day I check my phone to see how much electricity was generated and how much I earned. I'll recover my investment in less than a year, and after that it's pure profit.
Since installing this variable-pitch wind turbine, the battery hasn’t run low again. Before, I used to worry whenever we had consecutive overcast days and light winds in the winter, but now it can even charge the battery in low winds. Best of all, it doesn’t suddenly start screeching during gusts, so it doesn’t disturb my family’s sleep. The installer also mentioned that variable-pitch turbines are easier to calibrate than fixed-pitch ones. I give it five stars!
“I built a small pico hydro system on the creek behind my off-grid cabin. The water head is only 3 meters and flow rate around 0.2 m³/s – too low for most generators. This axial flux coreless unit starts generating usable power at just 150 RPM. No cogging, no iron loss, and it’s silent. I’m getting 300-400W continuously, 24/7. My old induction generator would barely light an LED at that speed. Absolutely perfect for low-head hydro.”
