Problem with battery I set in my design

Hi there,

I've prepared an IDF file for my project, which includes PV panels and a battery. Unfortunately, after running the simulation, the variables for the battery are not being displayed. I'm concerned that there might be an issue with the battery setup. I would greatly appreciate any help in resolving this problem, as I'm in a bit of a hurry for the results. I've attached the IDF file for your reference.

Thanks in advance!

Go over the eplusout.err file:

************* Simulation Error Summary *************
** Warning ** The following Report Variables were requested but not generated -- check.rdd file
**   ~~~   ** Either the IDF did not contain these elements, the variable name is misspelled,
**   ~~~   ** or the requested variable is an advanced output which requires Output : Diagnostics, DisplayAdvancedReportVariables;
  ************* Key=*, VarName=ELECTRIC STORAGE CHARGE ENERGY, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE ENERGY, Frequency=TimeStep
  ************* Key=*, VarName=TRANSFORMER OUTPUT ELECTRICITY ENERGY, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE ENERGY, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE BATTERY CHARGE STATE, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE CHARGE POWER, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE CHARGE ENERGY, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE POWER, Frequency=TimeStep
  ************* Key=*, VarName=ELECTRIC STORAGE DISCHARGE ENERGY, Frequency=TimeStep

The requested output variables are not listed in the .rdd file, so the requests are ignored. As suggested by @rraustad, try changing the electrical buss type ("DirectCurrentWithInverterDCStorage" instead of "DirectCurrentWithInverter"), e.g.:

ElectricLoadCenter:Distribution,
    Main Electric Load Center,
    PV Array Generator,
    TrackElectrical,
    0,
    ,
    ,
    DirectCurrentWithInverterDCStorage,   !- Electrical Buss Type
    PV Inverter,
    LG Chem RESU16H Battery,
    ,
    TrackFacilityElectricDemandStoreExcessOnSite,
    ,
    ,
    0.95,
    0.2;

Works on my end.
