Ok, so I have been seeing thread after thread where people are having a multitude of issues with the PW. Since I am just getting ready to do a site survey for my Tesla PV system, I thought I would ask if any forum members out there have any good things to say about their PW's. I am in line for the PW, but could switch to the Smart Battery if it makes more sense. So please chime in if you have installed a PW and have had no issue with it at all. Thanks!
