Question for y'all: I recently bought the following monitor:
to measure the wattage of multiple appliances / devices in my house so I could figure out what my future solar panel system would cover. I had always used tables like these as a rough approximation: http://www.i4at.org/surv/wattage.htm and figured I would not have a big enough system for things like AC or fridge/freezers. My system was emergency power only (e.g., lights, fans, etc).
The monitor seemed pretty accurate as I tried it on numerous items in my house like lamps, TVs, laptops, water heaters, electric fans, etc. But when I plugged it into my upright freezer (Frigidaire, forget the size in cubic feet, but it stands about 5 feet high) it shows only between 120-125 watts. I've had it plugged in for several hours now and it still says that.
Is this true? If I google "freezer" and "wattage" I get anywhere from 500-800 watts on average, yet my fridge is showing only 121 watts and it's sitting in my garage and it's 100 degrees outside in Dallas. I thought maybe the meter was reading incorrectly but (1) it's read all my other appliances pretty much what i expected and (2) this guy on youtube seems to have a similar reading: http://www.youtube.com/watch?v=vEQsjPhZ80c
Am I missing something? Thanks in advance for any help.
