The slow response on the frequency shift is for the XW+ only, and mine is an early model with no firmware updates since new. The XW Pro's main difference from the XW+ besides UL1741-SA is a much faster processor. I've heard that the frequency shift works quite well now, especially with UL1741-SA grid tie inverters.
