Hi CA Traveler,
Thanks for pointing that out to me.
It is an absorption fridge--so as voltage rises it uses more power, when the autoformer is doing its "thing". The recovery time is less than a second.
I can certainly repeat the test with the fridge off for start up measurements. I suppose I could run the fridge on propane. I don't see any point in having the inverter/charger off as it was drawing essentially nothing. I.E. not in load support mode, so the inverter was off.

Don,
Very interesting numbers which show constant amps (12.4A) with changing voltage for the refer and A/C. If the refer is the absorption type then it uses less amps with decreasing voltage and hence the A/C uses more.
It would be interesting to see the numbers for the A/C only, all other appliances off.
