Grid-Tie (Synchronous) Inverters for Wind Energy Systems

Grid-tie inverters are used for wind energy systems that are integrated with the grid. Like all inverters, it converts direct current energy (DC) to alternating current energy (AC), the kind you use to power everything from electric shavers to televisions.

A synchronous inverter also regulates the source of your electricity. If it is a nice, windy day, the synchronous converter will draw energy from your wind energy system. If it is a windless day, the synchronous inverter will route energy from the grid to your residence or business. The inverter has to be matched with the wattage output of your wind turbine.

Net metering

Synchronous inverters are also designed to be used with net metering. This process (if available in your area) allows you to sell energy you generate with your wind turbine back to your local energy supplier to alleviate your energy costs.

Multi-function inverters (hybrid-power inverters)

Some experts consider these a separate type of inverter altogether. A multi-function inverter is additionally connected to a battery bank and a standby generator. The battery bank allows you to store power, to rely even less on conventional grid power sources.

If there is no wind energy available, the multi-function inverter may draw your needed electricity from your battery bank. If the battery bank is drained, the inverter will draw power from the conventional grid (utility lines).
