Cause

Looks like a bug due to a copy/paste typo (see below) where the code to ForwardTranslate the Design Maximum Continuous Input Power field is actually setting the Simple Fixed Efficiency field and using the same variable optD. Feel free to open an issue in the OpenStudio repo.

https://github.com/NREL/OpenStudio/blob/develop/src/energyplus/ForwardTranslator/ForwardTranslateElectricLoadCenterStorageConverter.cpp#L75-L85https://github.com/NREL/OpenStudio/blame/1e4f9fda38c9a4917b3a4a196a6c9f80d469502c/src/energyplus/ForwardTranslator/ForwardTranslateElectricLoadCenterStorageConverter.cpp#L75-L85

// SimpleFixedEfficiency, optD
optD = modelObject.simpleFixedEfficiency();
if (optD) {
  idfObject.setDouble(ElectricLoadCenter_Storage_ConverterFields::SimpleFixedEfficiency, *optD);
}

// designMaximumContinuousInputPower, optD
optD = modelObject.designMaximumContinuousInputPower();
if (optD) {
  idfObject.setDouble(ElectricLoadCenter_Storage_ConverterFields::SimpleFixedEfficiency, *optD);
}

Solution

As a workaround you could write a simple EnergyPlus measure to fix the IDF after it's been translated by OpenStudio, which would look something like this.

# get all objects
electric_load_center_storage_converters = workspace.getObjectsByType('ElectricLoadCenter:Storage:Converter'.to_IddObjectType)
# OR
# get one object, e.g. if there's only one in the model
electric_load_center_storage_converter = workspace.getObjectsByType('ElectricLoadCenter:Storage:Converter'.to_IddObjectType).first

# set Simple Fixed Efficiency field to 0 rather than what's entered in the Design Maximum Continuous Input Power field
electric_load_center_storage_converter.setDouble(3, 0)
