The AC inverter power(W) is 0

Hi everyone,

I tried the PVWatts(Residential) module to produce solar generation data using 1-minute time resolution weather data. PVWatts did not remind me of any error. However, the AC inverter power is 0. The default parameters in System Design was selected. I tried to attach weather data but failed. Part of the data is as follows. Did you encounter this problem?

Best regards,
Paul.
