Very interested in this battery, thanks for the good review. I think that your total KWH output from the Killawatt meter may have been that low because of the idle draw from the huge 3000w inverter. It would be interesting to run a test for the same time and see what the idle draw of the invert is for the same amount of time. Or perhaps the specs for the inverter tells the idle draw. Then you can calculate how much for that time and see if it makes up the difference between the 153 you got and the 180 advertised.
