What You Need to Know

Maintenance Requirements:

Service once every 3 years by the installer, Sustainable Energy Development

My Motivation:

Desire to have cost-effective net zero energy home that will save $165,000 in energy costs over 20 years. The small wind turbine is one of three components. The other two are a 10 kW PV system and open loop geothermal heat pump system which combined generate 19,000+ kWh per year which is enough for heating, AC, hot water, all electrical systems PLUS 18,000 miles per year driving of my electric car.

Advice:

In order to improve the efficience of my small turbine I had to replace the factory supplied inverter (GridTek 10) with two Aurora inverters. The GridTek10 still works and is in place as a backup. Bergy Wind Power now has a much better turbine inverter and inverter, PowerSync II, so future customers will not need to make the changes I made.
