Powerwall 3 in Italy: 1-3 s power gap at backup switch, per user report
Unconfirmed: A user in Italy with a Powerwall 3 and an 11.25 kWp solar array (installed May 2025, firmware 26.26.11-pc 0d5e28c6) describes a power interruption of about 1 to 3 seconds when the system switched to backup during a grid outage on 8 October 2026, at around 20:50 local time. He clarifies that this is his observation, not a measured transfer time. Five-minute energy data show about 65% battery state of charge and a household load of roughly 1.1 kW.…
- 1-3 s power gap at backup switch, per user observation, not measurement
- Five-minute data: ~65% battery and ~1.1 kW household load
🔎 Why it matters: There is no official confirmation from Tesla. The claim is a 1-3 s interruption when a Powerwall 3 running firmware 26.26.11-pc switched to backup in Italy, as observed by the user himself.
📈 Upside: Not applicable.
📉 Risk: If the 1-3 s gap repeats, the house loses power for that interval during each grid outage, and the diagnostic codes mentioned in the title are not detailed in the available text.
