Powerwall — Common Questions
What is the Tesla Powerwall warranty?
Tesla Powerwall 2 and Powerwall 3 carry a 10-year warranty covering defects and capacity retention (70% at 10 years with unlimited cycles). Powerwall 1 has a 10-year warranty as well. Warranty service is handled through Tesla — we provide diagnostic documentation to support your claim.
Why is my Powerwall not charging?
A Powerwall that is not charging can be caused by a software or firmware issue, a gateway communication fault, a solar inverter problem preventing charging, a grid connection issue, or a hardware fault in the Powerwall itself. We diagnose all of these scenarios on-site.
Can you service a Powerwall from a company that went out of business?
Yes. We service Powerwall systems from any installer. We can troubleshoot gateway connectivity, reconfigure backup settings, and perform diagnostic work regardless of who originally installed the system.
What is the difference between Powerwall 2 and Powerwall 3?
The Powerwall 3 is Tesla's current generation with 13.5 kWh capacity and an integrated solar inverter (no separate solar inverter needed). The Powerwall 2 also has 13.5 kWh capacity but requires a separate solar inverter. Both are serviceable by us.
My Powerwall backup duration seems shorter than it used to be — is that normal?
Some capacity loss over time is normal — Powerwall is warranted to retain 70% capacity at 10 years. If your backup duration has dropped significantly in a short period, it may indicate a cell degradation issue or a configuration problem. We perform a state of health check to determine the cause.
