I haven't had any hardware related issues that required support as far as obtaining replacement parts, can't speak to that issue directly. I did have a menu configuration and set up conflict in the beginning. Turned out to be simple fix related to one of the settings. Having first called Schneider support at the published number and getting no where, I contacted Tom at Solarbiz and he gave me a phone number of someone to call. Turned out to be Eric Benston the lead applications engineer for Schneider Solar. Same guy who does many of the Schneider videos on YT. He had the answer in 30 seconds.
If our XW+ quit working tomorrow, I'd be purchasing the new XW Pro replacement from SolarBiz.
