Hello,
We have not developed a utility to transfer data between SAM and EnergyPlus. You would have to design the system in SAM to be equivalent to the system you designed in EnergyPlus.
You posted your question on the SDK forum, so I'm not sure if you are asking about running SAM's PV model (pvsamv1) via the SAM API or in the SAM user interface. In either case the answer is the same, although if you are writing code to run pvsamv1 via the API, there may be a way to automate translating the EnergyPlus inputs into SAM inputs.
Best regards,
Paul.
