<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Thanks for the reply. I have used that strategy successfully with other Types, but unfortunately the inverter just ignores the switch. A message in the List file
says ”The input to the listed units have not converged at this timestep. The values at the last iteration will be used and the simulation will proceed”.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Is there a way to deactivate a battery (Type 47a) without having to delete it from a model? I want to do an optimization that includes options with and without battery, so I need
to find a way to give the battery zero capacity or stop the inverter from charging/discharging it. I have tried different values for High and Low limit on FSOC but the inverter basically ignores them when the value doesn’t converge. Any suggestions?<o:p></o:p></p>
