2kW Small Wind Turbine – 3.2m Rotor, 4,000 kWh/Year

Name: 2 kW small wind turbine
Brand: WINDTURBINE
SKU: WT-2000H

Two kilowatts is roughly 4,000 kWh a year in a 5 m/s site — more than a heat pump's annual demand in a mild climate, and comfortably beyond what an off-grid household with a fridge, pump and power tools needs. The 3.2 m rotor keeps torque low enough that the machine starts at 3 m/s and reaches rated output at 11 m/s.

The tower is the deciding cost at this size. A 12 m tilt-up tower suits a suburban plot; a 15 m free-standing lattice tower is what we ship for farms and telecom compounds, where the extra height is worth more than the extra steel.

Design details

3.2 m rotor, 8 m² swept area

Low-solidity three-blade rotor: high tip-speed ratio, low starting torque, quiet at the blade tips.

96 V DC option for long cable runs

Doubling the voltage halves the cable loss — useful when the tower sits 200 m from the battery room.

Hydraulic or manual tilt

Tilt the tower down for blade service instead of climbing; a hydraulic ram kit is available for 12 m towers.

Grid-tie, off-grid or hybrid

2 kW inverter for grid-tie, 96 V MPPT for battery, or a hybrid controller taking 3 kW of PV on the same bus.

Where it is used

All-electric off-grid homes

4,000 kWh a year covers lighting, refrigeration, pumping, cooking and a heat pump in a well-insulated house.

Farm irrigation and cold storage

Runs a 1.5 kW pump during the day and charges the cold-room battery at night.

Small telecom and micro-grid

Two or three units in parallel form a 4–6 kW wind array for a village micro-grid.

Frequently asked questions

How tall should the tower be for a 2 kW turbine?

12 m minimum on open land, 15 m if anything within 100 m is taller than 5 m. A rule of thumb: hub height should clear the nearest obstacle by at least 10 m.

Can two 2 kW turbines run in parallel?

Yes. With the hybrid controller each turbine has its own MPPT input and they share the DC bus; the controllers communicate to avoid hunting. Up to four units are supported.

What battery bank does it need?

For a 4 kWh daily load with two days of autonomy, a 48 V / 400 Ah lithium bank (about 20 kWh) or 96 V / 200 Ah. Lead-acid needs roughly double the nominal capacity.
