Tesla Energy, SolarCity & Powerwall Orphan System Rescue: Account Transfer & Gateway Reset
How to claim ownership of a legacy SolarCity system or a Tesla Powerwall installed by a bankrupt third-party Certified Installer, reconnect a Tesla Backup Gateway 2 to Wi-Fi, and schedule direct Tesla Energy warranty repairs.
1. Step-by-Step Homeowner Emergency Rescue Protocol
Step 1 — Claim Instant Ownership Inside the Tesla App Using the Gateway QR Code: Whether your Powerwall or Tesla Solar Inverter was installed by Tesla Direct or by a third-party Certified Installer that went bankrupt (like Titan Solar or ADT Solar), you can register it directly to your personal Tesla account. Open the Tesla App -> tap "Add Product" -> scan the QR code sticker inside the door of your white Tesla Backup Gateway 2 (or on the side of your Powerwall 3).
Step 2 — Upload Your Property Deed or Original Installation Invoice for Legacy SolarCity Transfers: If you bought a home with a legacy SolarCity lease, PPA, or cash system (installed 2010–2017), go to tesla.com/support/energy/solar-panels/after-installation/transferring-ownership to transfer the account and remaining 20-year warranty into your name at $0 transfer fee.
Step 3 — Re-Commission a Disconnected Tesla Backup Gateway 2 (TEG) to Your Home Wi-Fi: If your Powerwall shows "Offline," open the Tesla Backup Gateway door, press and hold the recessed Reset button with a paperclip for 5 seconds until the LED flashes, then connect your smartphone to the "TEG-XXX" Wi-Fi network (password is the letter "S" followed by the last 7 characters of the Gateway serial number) and navigate to http://192.168.91.1 to configure your home 2.4GHz Wi-Fi.
Step 4 — Schedule Tesla Mobile Service or Certified Installer Warranty Repair via the Tesla App: For any hardware failure on a Tesla Solar Inverter or Powerwall (covered by Tesla’s 10-year unlimited-cycle Powerwall warranty and 12.5-year inverter warranty), open the Tesla App -> Support -> Service to trigger remote firmware diagnostics and dispatch either a Tesla Energy field technician or a newly reassigned Certified Installer.

My Powerwall was installed by a third-party company (like Titan Solar or Sunpro) that went bankrupt. Does Tesla still honor the 10-year warranty?
Yes, 100%! Every Tesla Powerwall 2, Powerwall+, and Powerwall 3 carries a direct 10-year manufacturer warranty from Tesla, Inc. guaranteeing at least 70% capacity retention. If your original Certified Installer went out of business, Tesla Support (877-961-7652) will either dispatch a Tesla Energy tech or assign a new active Certified Installer in your zip code.
My legacy 2014 SolarCity system has a dead ABB or Fronius string inverter and my 10-year inverter warranty just expired. What should I do?
Do not pay $5,000+ for an overpriced replacement! Because SolarCity systems use standard high-voltage DC strings (typically 300V–500V DC without panel-level proprietary locks), any local solar electrician can swap a dead ABB or Fronius inverter for a brand-new 6kW–8kW string or hybrid inverter for $1,400–$2,200 installed.
What if my Tesla Solar Inverter fan or coolant pump fails (alerting "Inverter Reduced Output")?
Tesla Solar Inverters and Powerwall+ units use a liquid glycol cooling loop with a miniature pump on the upper right side. This is a known warranty item covered for 12.5 years on the inverter—open a ticket inside the Tesla App and Tesla will replace the fan/pump assembly free of charge.
