After Solar Panels,Solar Inverters are the second most crucial component of the overall solar system accounting for around 10% of the overall costs.Solar inverters connect the solar panels to the grid converting the DC to AC which is used by the grid.Note for off grid solar installations,solar inverters are required as most electrical devices need AC for their operation.There are both grid tied and non grid tied inverters available on the market.Solar inverters have become highly sophisticated with features like optimization and monitoring etc.The efficiency of solar inverters are a major factor in their purchase as well as the quality and reliability.Inverters comes in various sizes and can be as large as 1 MW for utility applications.Note unlike solar panels,solar inverter manufactures are much bigger in size with SMA Solar having a 40% global marketshare.
