Thanks for the info. I have a 10,000 watt inverter with 600w solar panels and a wind turbine. But at night with no sunlight and maybe no wind, I need to know if the batteries will just run the fridge at night. I know now thanks to this video and can go off grid.
Inverter idle consumption is generally a function of the inverter's maximum output capability. So a solution, other than buying a DC fridge, is to use a dedicated inverter for the fridge that is just big enough to run it. Many fridges are soft-start (no major compressor surge), or even use DC compressors (no surge at all and a 0.90+ power factor). It usually doesn't take much of an inverter to run them. 1-2 kWh/day is pretty typical for a modern full-sized fridge, inclusive of inverter overhead, so your results are not completely out of line. Something like a simple 1500W 48V Reliable Electric inverter has an idle consumption of around 16W, Lets see... and I have an 800W 24V Reliable Electric inverter whos idle consumption of around 9W. -Matt
Thanks, Matt! My inverter is for backup during a power outage, to power lights, fridge, microwave, small AC units. Some people are just needing to run a fridge and a few lights. Do you know of any refrigerator models that are soft-start? I'm aware of DC fridges, mostly for RV or mobile use.
My 15 year old fridge showed 1640 W for a split second on the" kilowatt" meter when the compressor started. But after I get similar measurements during the cooling cycle of about 140 W. Going to use two 12V 100ah batteries in series with a 1200 Watt 24V inverter that has a surge peak of 2200W. Think this will handle that fridge?
That depends on the inverter. Some inverters can actually do what their specs say, others can't. At 24 volts, you be puling around 68 amps surge. Make sure your wiring and BMS can handle it.

Very clear explanation with real world data!
Good info.

Great video and demo. Thanks.

@@ReelClearMediaLLC You can get a fridge with Inverter compressor that barely has any surge at all, same for the A/C with inverter compressor.
@@budmartin3344 I have a Midea U-shaped AC with inverter compressor. Sips electricity and no surge.

Thanks, planning on that amount. BMS can do 100Amps and Victron Phoenix 24/1200 specs are up to the task.
DC refrigerator says hello.
newer refrigerators are a lot more efficient than older refrigerators...
Yes, thats good. Unfortunately, I've noticed a lot of the fridges at the "big box" stores don't even show the energy use anymore.
