Morningstar’s String Sizing Calculator Has Been Updated

We are happy to inform you that the Morningstar string sizing calculator has been updated. This string sizer is used to determine the number of PV modules you may use with any Morningstar controller while staying within the controller specs.  Thousands of additional modules from new manufacturers were added to the database, and the new interface displays additional information and specifications associated with your module and product selections.
