Hi Aproop,
I am not aware of a step-by-step guide for modeling off-grid solar-plus-storage systems in SAM. The following videos on the
Battery Videos page
might be helpful:
Modeling Battery Systems in SAM 2020.2.29: Behind-the-Meter Systems
Behind-the-meter Battery Dispatch Options for SAM Fall 2023
If you are new to SAM, you might also refer to the "Getting Started" and "Reference" sections of SAM's Help system which you can find by pressing the F1 key or clicking Help in SAM.
SAM is not designed to model off-grid systems, but the following topics discuss some approaches you can use to approximate an off-grid system:
