Permanent magnet generators provide efficient energy conversion, especially under partial load, and do not require a separate excitation system. Compared with competing designs, our permanent magnet generators are lighter, more efficient, and require less assembly labor. Permanent magnet generators are used in a large number of applications such as wind turbines, hydroturbines, and electric motors.

Sweden Oct 17.2025
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.

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 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.
