DOMUS 500 W Compact Vertical Wind Turbine

The DOMUS 500 W is the lower-power of the two DOMUS wind turbines (500 and 750 W): 500 W maximum power, 300 W rated power, and it starts producing at 2.4 m/s, which is a 0.4 m/s lower wind speed than the DOMUS 750 W needs. It suits sites where 300 W of rated power is enough and the wind is often light. Vertical axis, 12 kg, direct drive, noise level below 40 dB.

Technical specifications

How the DOMUS 500 W differs from the DOMUS 750 W

Dimensions (80 × 80 × 130 cm), weight (12 kg), noise level, drive, blades and configurations are the same for both models, so the choice comes down to power and wind. Choose the DOMUS 500 W if 300 W of rated power is enough or the wind at your site is often light: it starts producing at 2.4 m/s. If you need 500 W of rated power and the site gets enough wind, look at the DOMUS 750 W, which starts at 2.8 m/s.

Vertical wind turbine for home: what is the DOMUS 500 W for?

• Reducing electricity bills when the system is grid-connected (Grid Connected)
• Storing energy in batteries (Stand Alone)
• Domestic and industrial use, and smaller commercial projects

Wind turbine for 12 / 24 V batteries: how to connect it

The DOMUS 500 W is designed for 12 / 24 V DC battery systems, and the output is three-phase alternating current (AC) up to 36 V. Batteries are not included. The manufacturer offers several configurations:

• PLUS: rotor M28, generator M12, rectifier M36 and mast M40 (85 cm)
• Stand Alone: PLUS, controller M26 and off-grid inverter M22 (battery not included)
• Grid Connected: PLUS, controller M26 and grid inverter M34 (battery not included)
• Full: PLUS, controller M26, inverters M22 and M34 (batteries not included)

The technical data does not list specific battery or inverter models, so we check compatibility for each project separately.

How to choose a small wind turbine for a house by power and wind

Plan around the rated power, which is 300 W for the DOMUS 500 W, not the 500 W maximum power. The starting wind speed matters too: the turbine starts producing at 2.4 m/s, so at a site where the wind rarely reaches this speed, output will be low. Before you buy, tell us where you plan to install it and we will assess the site and mast height together.

What wind must a wind turbine mast withstand?

According to the Lithuanian Hydrometeorological Service:

“The highest wind speed recorded in Lithuania’s observation history was 40 m/s.”

So it matters not only at what wind speed the equipment starts, but also how the mast is secured: the foundation, guy wires and fixings.

We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
