Wind energy MPPT with 98% engagement to actual wind energy output curve for maximum power generation enhancement.

Safety Protection

Comprehensive protection including over-voltage, over-current, anti-reverse connection, and short circuit protection.

IoT Functionality

Wired network with APP remote viewing and control
Remote data export capability

Touch Screen Interface

Displays voltage, current, power, generation status, and operation status with alarm query
Historical data and alarm information date query
On-site parameter adjustment

Custom Wind Energy Power Absorption Circuit

Modularized, hot-swappable power absorption circuit for easy maintenance
Input/output electrical isolation to protect back-end loads
High efficiency at low wind speeds with wide input voltage range
Saturation mode for matching load power output

PWM Unloading

Fan self-powered mode with fast response
Speed and torque limitation for safe wind turbine operation
Soft unloading adjustment to reduce fan output burden

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.

My farm is 30 kilometers from town, and connecting to the power grid would cost a fortune. Three years ago, I installed a solar panel system with a battery bank. It was sufficient during spring, summer, and fall, but in winter, we often had a week of consecutive overcast days—and the batteries would run out in just three days. Last year, I decided to add a variable-pitch wind turbine, connected it to the AC coupling port of the Deye inverter, and set up a hybrid solar-wind system. Throughout the entire winter, the battery level never dropped below 45%, and I never had to work in the dark again. The Deye app allows me to monitor both the solar and wind turbine data simultaneously, and the transition between them is so smooth it’s almost imperceptible. Relying solely on solar power during winter on a Nordic farm is a gamble. Only by combining a variable-pitch wind turbine with a Deye inverter—creating a wind-solar hybrid system—can you get through the winter with peace of mind.

I run a small dairy farm in northern Norway, far from the power grid. A few years ago, I installed solar panels and a Deye inverter, but the solar system basically stops working in winter, and the diesel generator was costing me a fortune. This year, I added this variable-pitch wind turbine and connected it to the Deye inverter for a hybrid solar-wind system, and we haven’t had a single power outage all winter. This wind turbine starts up at low wind speeds of just 2–3 on the Beaufort scale. During blizzards, the blades automatically pitch down to slow the turbine, preventing runaway speeds, and it’s much quieter than my neighbor’s fixed-pitch model. The Deye inverter’s switching logic is smart—it prioritizes solar power when available, and automatically switches to the wind turbine when solar output drops. It’s all clearly visible on the app. Now, the diesel generator is practically idle. Wind and solar backing each other up—that’s true off-grid freedom.
