I didn't mean "100% American". I meant unknown Chinese brands that you see in big box stores among more-less known international brands. They come and go. Unknown parts, unknown compressors.

Among "big brands" the energy numbers are still high, and are all over the board, from 300 to 450 KWH a year for 9cf fridge. With "low" 300 KWH it means 80 AH a day including inverter, or 120 AH with other trailer loads, for a conservative user. This means daily generator run, even if you don't need A/C. Will it really be 2 times more efficient than the nameplate says? Don't know. Nobody measured daily AH, only Westend did, in a smaller fridge. I think I'll wait until this picture clears up. Or until I get unlimited power supply, i.e. 120V grid, on the camp.

The Energy Star energy usage number for my fridge was 381kWh / year. I have been running my kill-a-watt usage meter on it for over a week. The initial 24 hours (starting temp 80F)it consumed about .68kWh. The average daily consumptions since then has been .54-.56kWh / day.

I don't know if there is any truth to it but I have heard that the Energy Star test standard imposes an ambient temperature for testing of 90F. If so, this would give a fair comparison between models but would not yield realistic numbers for most average consumers.

Bottom line:
Energy Star estimate - 1.04kWh daily
Measured consumption - <.6kWh daily

Hey Steve. Does that fridge have auto defrost on it. I would prefer it doesn't as the auto defrost sucks up bunches of power and in our case it wouldn't be on more more then a month at a time. Thanks in advance.

By the way, thanks for the numbers. yu da man

Yes it does have auto defrost.

It also has a very nice schematic diagram on the back that points you very easily to the easily accessible plug/connector that you need to unplug to disable the auto defrost. At some point I will likely install a switch.
