The most common transformer style utilized in renewable energy applications are Inverter Transformers, which convert the DC power provided from the energy-harvesting device to AC power for use in household, business, and electrical-grid environments.

Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.
