I had some push back for support from Tesla..... In fact they threatened to not allow my installation. I finally got this response:
Thank you for your patience. I have received word from my tier 2 team regarding your case. We only design off-grid systems for customers who are unable to receive electricity from a local utility company, but not for customers who already have service from a local utility company. It was mentioned that it would be fine if you decide to work with a Certified Tesla Installer to re-design to go completely off-grid which will not void your warranty as long as the limited warranty guidelines are followed. It was advised that if the off-grid requirements are not followed then performance cannot be guaranteed. I have included a link for the warranty document and how to find a Certified Tesla Installer in your area below.

I was hoping for a little stronger support, but I am satisfied that using off grid (disconnected from PG&E) will not void the warranty that I have with Tesla. I am using a certified installer to complete the installation. I hope that my case will encourage others to follow and "
cut the cord" !
Presently I am waiting for the generator to be delivered to complete the process. It is supposed to ship next week! I ordered it in May and deliveries are backlogged.
