LEC 240V fridge power consumption with inverter / power audit

Search mode on the Victron inverters puts out very short mains bursts, something like a couple of mains cycles once every few seconds IIRC. If this wasn't enough to wake your fridge up then this would explain what you saw -- doesn't mean this happens with all inverters and all modern fridges though...

But you won't know until you try it 🤭

That doesn't sound too good. According to the instructions posted by A de E, when run directly on 12V it should consume 8A. So either your inverter is consuming a lot of power, or your fridge is much less efficient than it was designed to be.

 

Looking at the specs I posted above isn't 0.54A AC = 11.43A DC? That's exactly what I'm getting on my battery monitor.

110kWh/year for an 88l fridge isn't especially good, but you might not be able to find anything better in such a small (narrow) fridge where it's harder to get enough insulation in.

 

But it's rated A+ (or F)? So what sort of figure would you be looking for?

Obviously. So some don't work and some do. YMMV.

The best one you can find for the money you're willing to pay 😉

Ok but it seems to be comparable to similar size fridges.

But he is not running the fridge on 12 volts. he is running the invertor on 12 volts and the fridge on 240 volts, it "may" have a thermostat on 240 volts I don't know

 

I think David meant that if it's using 8amps directly from 12v DC it should be doing better running from AC not worse.

 

However the fridge specs seem to be what I'm getting.
