A good inverter is key to the success of a wind system, so shop carefully. Size it appropriately. Be sure to consider future electrical needs. But don’t forget that you can trim electrical consumption through conservation and efficiency. Efficiency is always cheaper than adding more capacity! When shopping, select the features you want and buy the best inverter you can afford. Although modified square wave inverters work for most applications, you will most likely be happier with a sine wave inverter. If you are installing a grid-connected system, you must install a sine wave inverter.
