User Reports Powerwall 2 Calibrations During Peak Usage Window
Unconfirmed: A user on an owners' forum says two Powerwall 2 units enter calibrations that leave them idle during the peak usage window, when he says they should be at 100%. He says the units had honored that window for three years, but routine calibrations have started running every month. He reports paying kW demand charges during that period and asks how to keep calibration from interfering with the window. The post is cut off, so not all of the consequences he describes are known. There is no official Tesla source backing this.
- Per the user, two Powerwall 2 units sit idle during the peak window.
- Monthly calibrations reportedly began after three years of honoring the usage window.
🔎 Why it matters: No official confirmation: the user claims monthly calibrations leave two Powerwall 2 units short of full charge during the peak window, where he pays kW demand charges.
📈 Upside: Not applicable.
📉 Risk: If monthly calibration keeps overlapping the peak window, the user's kW charges would remain uncovered by battery.
