Wind Turbine Inverters

Power One - Trio Inverter

The inverter is a key component of any wind turbine system. Inverters are units which convert the direct current (DC) power produced by wind turbines into alternating current (AC) which can be used to power appliances in homes and business, or exported to the electricity grid.

The specifications - and therefore the cost - of the inverter will vary depending on the size and power output of the wind turbine system. Inverters for small roof-mounted turbines can cost just a few hundred pounds. For other domestic pole-mounted systems (of up to 5-6 kW), you can typically expect to pay around £1,000 for an inverter. Larger and higher quality inverters can cost significantly more. Some larger turbines, such as the 10kW Xzeres 442SR come with inverters included.

Wind turbine installation companies should include the cost of the inverter and all other components in the initial quote.

Inverters tend to have a shorter life expectancy than the wind turbines themselves: manufacturers typically offer parts and service warranties of between 5 and 10 years.
