So a little background....I'm building a house (DFW area), which should have been finished earlier this year, but, it's not, maybe by the end of the year.... Anyway, I got a quote from a local installer last year, which was fine, however since then the Powerwall has become available in Texas, and it's something I'd like to add to the Solar configuration, more for brown-out protection than anything else (5500 sqft home, pool, AC etc, so the PW will just support the majority of 110v circuits) The installer I selected is not certified for PowerWall, so I've been chatting with Treehouse (out of Austin, but opening in DFW soon). They've provided a similar quote, so I reached back out to the original installer to break the agreement, It's their reply that I found interesting, and wondered whether it's FUD or not: ...We can install and give you a quote for a battery....even a powerwall if you would like. However if you have done any research as of late the Powerwall is failing BIG time, having issues and is getting the worst reviews. I will be happy to let you speak with my engineer who goes to all of the conventions and installs our batteries to explain the problems the customers are having with these powerwalls if you would like. I've not been staying that up to date with PowerWall, but equally I'm quite tight with the Tesla world and haven't heard anything bad. Have I missed something?
