Hello,
You can define the battery dispatch schedule on the Battery Storage input page -- look at the Storage Dispatch Controller and Manual Dispatch Model inputs.
The PV output profile depends on the weather data and design of your PV system. You can look at the "System power generated" variable on the Results page to see that information.
The building load is data that you provide on the Electric Load input page. You can use the "Download Electric Load" macro to download data for different kinds of buildings.
You can use the battery manual dispatch model to schedule the battery to operate during periods of low energy prices (determined by the data on the Electricity Rates input page).
You may want to review the list of webinar recordings on the Webinars page to learn more about modeling PV systems with storage:

You can also refer to SAM's help system for information about the models.
Best regards,
Paul.
