What does a Fridge amp rating mean?
I am going to help some off-grid neighbors set up a fridge to replace their propane on and a solar system to run it. I have measured a fridge that I own that is about 15 years old so I don't know if technology has improved, but looking at some discussions tells me it has not. The fridge I own draws a 2.4 second surge that is about 8 times the running current (1.2A RMS).
The reason they want electric is that they want a big fridge. I picked a Maytag 36" at random on their web site and it said it draws 20A. I am not sure what, exactly, this means. Seems high for running amps so is this actually the surge and the running amps are much less? Or what does that "20 A" mean?
I need to know so I can set up their requirements for panel wattage, battery bank and inverter size. I don't see inverters common for more than 2,000W, and it appears as though that unit may barely run the random pick I made.
Of course, they will pick a different fridge but the principles of sizing will be the same.
Thanks for any help,
