Small wind turbine · 3 kW class
The workhorse for farms, guesthouses and small businesses: 6,000 kWh a year, three-phase output, and a tower you can service with a standard ladder and harness rather than a crane.
At 3 kW the electrical side changes. Output can be 400 V three-phase, which means the turbine can feed a workshop panel or an irrigation pump directly, and the inverter no longer has to be a single-phase unit limited by the local supply.
Mechanically it is still a direct-drive machine with passive furling, deliberately: the failure modes of a small turbine are almost always in the gearbox, the slip ring or the yaw motor, and this design has none of the three.

Price depends on tower height, controller and battery bank — ask for a quote with your site details.
Optimised for 5–7 m/s sites; the power curve stays flat to 13 m/s before furling begins.
Feeds a workshop distribution board or a pump directly; no phase balancing on a weak single-phase supply.
For shelter belts and orchards where the first 12 m are turbulent.
Blade set, bearings, controller board and brake resistor kept in stock for this frame size.
Irrigation pumps, milking parlours, grain dryers and cold rooms running on 400 V.
Cuts the diesel generator hours to near zero between April and October.
Micro-grid anchor machine where a diesel generator is the only alternative.
