I am trying to model a very simple PV generator.

I tried to set availability to PV generators in "ElectricLoadCenter:Generators" class, but, this availability schedule didn't work at all. The generator works all the time regardless of its availability schedule.

And I got the warning message from .err file.

[ * Warning * GeneratorController constructor ElectricLoadCenter:Generators, Availability Schedule for Generator:PVWatts 'PV1' will be be ignored (runs all the time). ]

Is it normal situation? or is there any other way to use the availability schedule?
