Importing multiple PV or Wind datasets is a feature in both Pro and Grid. If you are using Pro (and the datasets are not Helioscope or PVSyst formats, they're just a single column 8760), then you would add multiple Custom Resources and tie each one to it's own Custom Component. Those can be either wind or PV datasets.



Screenshots above show how to add custom components and resources. When they are added, you will need to tie the resource to the component (see below). Use the Search Space feature to scale. 


If you are using Grid, import your wind/solar as seen below. Be sure to fill in required specs when the import feature prompts you to do so.
