The PV input number is from Midnite Classic 150s The Inverter output (power consumed) is from cheap ebay meters on each 120v leg of the AIMS.Its pretty cool that you've gathered/kept detailed data on conversion efficiency. How are you measuring/tracking this?
Efficiency % = "Ebay Meter Kwh" / "Midnite Classinc PV Kwh".
I understand there is a bit of fuzziness - such as 1%? loss in charge/discharge of 18650 powerwall - but I believe it's negligible and AIMS is the major efficiency loss.
