400W vertical axis wind turbine for homes, boats and off-grid lighting
A compact three-blade vertical turbine built around a coreless maglev generator. It starts turning at 1.3 m/s, begins charging at 2.5 m/s and reaches rated output at 10 m/s — the wind profile most residential and marine sites actually have, rather than the open-field conditions large horizontal turbines need. The MPPT controller is included at no extra cost.

Why vertical axis for a rooftop or a mast
A vertical rotor accepts wind from any direction without yawing, so it tolerates the turbulent, direction-shifting flow near buildings and along coastlines. Blade tip speed is lower than an equivalent horizontal machine, which keeps operating noise down — the reason this class of turbine is used for garden and street lighting, telecom sites, boats and camping setups.
Realistic expectations
Rated power means output at 10 m/s of steady wind. At an average site of 5–6 m/s, plan on a fraction of that figure over a day, and size your battery bank accordingly. Height matters more than any other variable: the same turbine on a 9 m mast will outproduce one bolted to a 3 m pole by a wide margin. Pair it with solar if you need year-round consistency.

Frequently asked questions
Does it need a tower, or can it be roof-mounted?
Both are possible within the 2–12 m mounting range, but a roof mount must be structurally isolated from living spaces to avoid transmitting vibration.
Is the controller really included?
Yes, an MPPT controller ships with the turbine at no additional charge.
How loud is it?
The coreless maglev generator and low tip speed keep it in the quiet range for its class; noise rises with wind speed and mount rigidity.
Can I connect it to the grid?
Not directly. The output is 12V/24V DC for battery charging; grid export requires a separate certified grid-tie inverter and utility approval.
What happens in a storm?
The electromagnetic brake and unloading unit engage on overspeed; survival wind speed is 40 m/s.
How long does shipping take?
Five to fifteen business days.
