If you leave it as an EPW file, the weather converter assumes that everything is okay. It will convert some things, such as dew point or relative humidity if those values are "missing" but not, I think, the solar values.
You will need to input it as a "custom" with a "definitions" file to get it to effect a split in solar. I would attach it here but the unmet hours will only apparently allow picture files. I will try to send it as a private message.
