Hi,
Maybe there is an Energy Star freezer in your future? I got my Ensupra a couple days ago --fast shipping. Seems like a nice unit -- have not a had a chance to do more than verify that it works OK yet. Gary |

That little freezer is using near max power right now.
In the cold weather, it uses a lot less. (My guess is <=$30 a year). One thing that I would like to do, is move the decimal point on the rate. Instead of 16.61, I would like to have 0.1661 Have not figured that out yet. If it's even possible. I recommend doing a couple of resets before setting the rate and first use. Might save you from any frozen Watts display.. Having $ displayed is not really a big deal, as long as the kWh number is accurate. I think that doing a reset is going to be common, since I'll want to restart measurements on a new load once in a while. The reset zeros the time, days & kWh..

I've been using the Ensupra meter to monitor power from a MSW inverter from my PV powered emergency backup system.
http://i46.photobucket.com/albums/f1...Solar/z203.jpg The load on the meter is from the A7 ASHP hot water heater.. It seems to be doing just fine, with a horrible "AC" source that looks a lot like this.. http://i46.photobucket.com/albums/f1...squarewave.jpg The displayed data is very similar to the normal output I see from the grid. I'm liking this new meter more every day!
