Specific residential Batteries

I am interested in modeling specific batteries (Powerwall 2, Resu10, etc.). I know that I can enter the desired bank size, chemistry, cell capacity, and other information, and that SAM will fill in the computed properties. This is probably close enough, but are their any plans to include the option of selecting name brands batteries with their actual specs, as opposed to the computed specs?

My intended use case is to use the variables in the SDK.

A followup question:

If I were to work with custom AC coupled batteries where the chemistry power input/extraction limit is greater than the inverter/rectifier, can I just reduce the 'batt_power_charge_max' and 'batt_power_discharge_max'? For a relatively generic system, reducing these variables (5.2 -> 0.2) results in a higher NPV, which seems counter-intuitive.

We are considering adding a battery library similar to the module and inverter library. However, there is not a good source of data for commercially available batteries (yet).

The module and inverter libraries and code that reads them are part of the SAM user interface, so are not available via the SSC API (SDK), although you could write your own code to parse the library CSV files that come with SAM.

Reducing the charge and discharge limits might have the effect of reducing battery losses and, depending on how you are modeling replacements, decreasing replacement costs as the amount of cycling is reduced. Both of those would increase the NPV.

Best regards,
Paul.
