For those curious to know what a modern 463 litre fridge consumes, here is the stats. Noone is home and noone has used the kitchen since midnight. The energy monitors have a small error where even if the kitchen is off it still reads about 10W. So the actual consumption is a bit less.

0.85 kWh over 16/17 hours is low in my book. Removing the errors in reading and its about 0.7kWh.

Yup fridges actually use very little power, people seem to think these are massive power hogs but they are not

Yeah, I shared my consumption as I did see on here people had a perception that the fridges are the main culprits for draining their batteries at night. My experience indicates otherwise.

Yeah at most an entire day the fridge will use 1 unit, the freezer about 1.2 (it runs a bit more).
Even both combined it uses barely anything. A fan running overnight actually can use more

What is the temp set to?
 
My chest freezer, which is the oldest freezer A+++++ + whatever rating-wise in the house, uses about 40 units a month. I don't even know what's in there or if it's just begging for a defrosting, caked up like a mofo.

Think I should check.
 
Yeah my two fridge/freezer combos use 3.5-3.7 kWh per day.

When we aren’t home and they don’t get opened it dips down to 2.8 kWh happily.
 
The only thing that affects power consumption is the thermostat setting, not how full it is from my experiments.

That actually does effect it. The more stuff it needs to keep cool the longer it runs. The emptier it is the more cooling it needs to do.
Freezers and fridges like to be around 30 to 80% full. Like batteries

From my experiments, the smart plug Wh was the same when empty or full. The only difference I would assume is the how often the compressor cycles on and off.

Ah that yes, the cycle would be more on than off

No idea. But one of the teens had left a fan plugged into the kitchen plug when we left the house for the 5 days.

It rained the same evening and tripped the earth leakage. The kitchen stayed without power till we came back. Things in the freezer compartment had defrosted but still quite cold.

I suspect the insulation is very good on the new fridges. It took almost 48 hours of continuous running for the fridge to switch off via thermostat after that though.

We have a basic Defy non-inverter fridge/freezer of 300 L and it does about the same - 30 W on average, 0.7 kWh/day.

It draws just under 100 W while running, so that's obviously the upper limit. But it has about a 30% duty cycle at the moment with the thermostat where it's at. It's probably not quite as cold as it should be but it's good enough for leftover pizza.

The longer duty cycle last night must have been because we used a bunch of ice cubes and replaced them with water... looks like it basically took all night to fully recover from that.
