battery issue

    In SAM (System Advisor Model), my battery stops discharging in certain years (for example years , 7, 9, 11, etc.). i am using "Replace at specified schedule" mode in the Battery Life settings. The annual battery discharge becomes zero for those years.Why does this happen, and what is the correct way to configure the battery replacement so that the system continues operating every year?      

Hi Khalifa,

I think this is due to an issue that we fixed for SAM 2025.4.16 ( github.com/NREL/ssc/issues/1171 ).

Please make sure you are using the latest version of SAM.

If you continue to see these results, please attach a copy of your .sam file so I can troubleshoot.

Best regards,
Paul.
