Re: Our New Cold Plate Fridge Reply #25 – July 28, 2013, 11:26:54 pm We'll arrive at AM Solar this Tuesday. Install on Wednesday.I have a Kill A Watt coming in to AM Solar and am hoping to use it to get an idea of how much energy our new fridge uses. Not having seen it, I assume the Kill A Watt measures AC only. Since the Danfoss compressor unit is DC I assume the energy used by the fridge would be less than I'll measure when it runs on DC.The Danfoss compressor is a treat. It's quiet and not even behind a panel yet and the best way to tell if it's on it to put your hand on it to see if there's any vibrations.I check the temps remotely. Right now at 8p it's down to 78F outside and no AC all day. So the fridge had no help from AC today. It's temps just now are 14F/39F.As I mentioned earlier, the temp that's controlled via a common dial setting is the freezer temp. That takes a bit of getting used to. The fridge temp is adjusted/controlled by a fan being ON or OFF. When the fan is ON it blows down into a shallow duct at the back of the fridge (the duct is about 1 inch deep, 12 inches high and somewhat less than the width of the fridge). The exit at the bottom of the duct can be OPEN or CLOSED. And of course, I also have recourse to changing the dial setting for the freezer. If you're a technoid like me, all in all it's pretty sweet. Kinda like my first MBZ, but a lot less $$$...But my engineering award for the year goes to Gillette. I picked up a pack of throwaway razors at Costco and am impressed. I usually don't shave until my beard is pretty long but these puppies don't clog or blink. I've been using the first one for 3 months now! I'll bet the engineer that designed these is looking for a job ;o)More later...best, paul Quote Selected

You plug it into a wall socket and then plug the appliance into the KAW.Craig Quote Selected

The KAW that I have is designed for 120VAC+- 60Hz+- only. The folk at AM Solar will have a suitable meter and will know exactly what to measure. Quote Selected

Re: Our New Cold Plate Fridge Reply #29 – August 01, 2013, 11:20:12 am My first reading with the Kill A Watt of fridge electric usage is 1.27 kwhr over 35 hrs = 36 watts per hour or an average of 3 amps per hour (if I did the calcs a right). Theoretically a bit less when the fridge runs on DC.Ambient temp averaged in the low 70s.best, paul Quote Selected
