Warranty
- Typical Coverage: Powerwall is warranted free from defects for ten years following initial installation, retaining at least 70% energy capacity at 10 years for solar self-consumption, time-based control, and backup applications, with unlimited cycles. Full 10-year coverage requires the unit to remain reliably connected to the internet for remote firmware updates; extended loss of connectivity can limit warranty coverage to 4 years.
- Eligibility: Warranty eligibility depends on purchase channel — our team confirms coverage for your specific order before you buy.
