Calibration
UK-based.
My PW3 started its first calibration yesterday, exactly 2 months to the day from install (even down to the time it was commissioned). This was a bit of a hole in my research pre-purchase, because I had no idea this was a thing and it was a surprise to find my battery discharging during peak hours and nowhere productive for my excess solar to go (I can’t export for money yet).
It’s been at 0% since about 1am (13 hours ago) and NetZero now shows the true State of Charge as 1%. I assume it will finish soon, but it was a surprise disruption.
I’m using the Powerwall to mitigate costs and not saving it for grid outages, so could really do with avoiding these. How can I reduce the number of these manual calibrations in the future? From research, I’ve seen people say they haven’t had a single one in years, and others getting one every six to eight weeks.
I have never run it 0% before, so is that the problem? Should I keep the reserve to 0% and force discharge it to 0% every 24 hours?
