7.5 amps how many times would this fridge run when full over a 12 hour period? Anyone got the stats?

Hi Southace

This might help. www.12volt.com.au/General%20Htmls/pdf/WAECO/Amps%20per%20hour.pdf

Regards Don

I have a Waeco compressor and evaporator unit installed in my self built box. It runs about 30-50% of the time. So at 7.5 AH x 6 hours (half of 12) will take 45 AH.

I've got 60l companion onboard and use about 20a/h a day, including lights and car radio. That's in northern NSW, winter air temp problely 20ish
ps. Check out the portable fridges at vic off-road

im trying on this trip the advice of someone on here (i cant remember who sorry, but thank you!)
Im leaving Sunday for QLD from Syd harbour and currently i have 5 frozen 2L milk bottles in the freezer(at home). Onboard i have an 80L Esky that ive swapped out with the cabin-to-cockpit steps. Had to shave the sides a bit for it to fit, but fit it does, very well. Paddle board grip on the top of it plus its a great seat. Behind this i have the fridge/freezer(where an inboard would have been) which im a bit scared to use as ive never really had enough grunt in the solar/battery departments. I think ive got enough power now, so the plan is after about 3/4 days, to re freeze the bottles in the freezer, which i experimented with in the car a few months back. Would only take a few hours to freeze these so im really hoping it will work ok. This means that according to the Waeco chart, my fridge running as a freezer will drain about 9amps to freeze my bottles which will keep everything cold in the esky for another 3/4 days. Its a good esky.
If this works it will be a good thing!

Or go with out a frig altogether. Victual the vessel like sailors do. Have a beer ashore when you get there!

I have a Waeco CR-80 upright fridge in my yacht. It cycles about 50% of the time in hot weather and draws about 3.5A. Over a 24 hr period that means it draws 24x0.5x3.5 = 42Ah.
