SSC requires input 'gen', but was not found in the SAM UI or from previous simulations

SSC requires input 'gen', but was not found in the SAM UI or from previous simulations was created by rafaelmorais
I am running a simulation on PV detailed (PPA single owner). I am using 2017.9.5 version. I uploaded a csv file with solar resource which was downloaded to NREL database. In inverter tab I input inverter datasheet.

By clicking on "Simulate" I find the message: "fail(subarray1_rotlim, min=5): 0
Simulation pvsamv1 failed.
SSC requires input 'gen', but was not found in the SAM UI or from previous simulations
Simulation singleowner failed."

I am just starting to simulate at SAM. Probably it is an user error. I´d appreciate if you´d take a look at this bug.

Find attached my .SAM file and error log.

Thanks,
Rafael.

Dear Rafael,

That error message means that you set the "Tracker rotation limit (deg)" on the System Design page to zero, but the minimum acceptable value is 5 degrees. You should change the value to 5 or greater to fix the problem.

Best regards,
Paul.
