SAM's battery storage model is for the following types of batteries
It can model the following types of battery storage projects:
Although SAM does not have a standalone battery model, a standalone storage system can be modeled using the techniques described in this webinar. NREL plans to add a standalone battery model to SAM in late 2019 or early 2020.
SAM's battery storage model is available with the Detailed Photovoltaic, PVWatts, and Generic System performance models.
Nicholas Diorio describes and demonstrates the new battery model features in SAM 2017.1.17. These include:
For an introduction to SAM's PV-battery model, see Modeling a photovoltaic battery system in SAM 2016.3.14.
Nicholas DiOrio builds on the Modeling a Residential Photovoltaic System by continuing the demonstration and adding a battery storage system to the residential photovoltaic system. We will cover battery design parameters, dispatch options, and analyzing battery results.
Nicholas DiOrio describes the battery storage model that is part of SAM's detailed photovoltaic model on September 17, 2015.
NREL's Nicholas DiOrio introduces a pre-release Beta version of SAM's new battery model for photovoltaic systems. For a more up-to-date presentation of the model, see Battery Storage for Photovoltaic Systems, Sep 2015 above.

SAM's default battery cost values were chosen to be roughly representative of battery costs for a project in the United States to help you get started using the model. You should review and change those costs for your own analysis.
Default battery costs are from the NREL Annual Technology Baseline.
