Hello, if I have a digital meter, the extra energy produccion (at day ) when back to the grid, count the energy like "consumption" or simply don't ?

you are right, generally digital meters, even the mechanical/digital ones will only go up, so you will pay for giving the utility your power. If you are using, however, it will slow the meter down, so you would pay less. Best to turn it on when you turn on an appliance, and off afterwards.

I can't say I noticed a serious spike in my bill. I don't run this unit on a continued basis. I would imagine you can contact the manufacture for usage data.

The device will record power usage for any period of time you require it to. So you can record for 1 hour, 1 day, 1 week or 1 month. For an appliance that runs intermittently (like a dehumidifier) you may wish to record usage for 1 week. Then you can extrapolate for the month by multiplying the 1 week consumption by 4. I will not record each interval the device runs separately however. So if you're looking for a series of readings representing each time it ran during that 1 week period, it will not do that. Hope this helps answer your question!

no . i would go with a trace . may be you should change it over to gas . and i have see a conversion to dc units out their . i got a gas frig . as so what it use 200 gal a year . alot cheaper than all those panels etc .

Heck yes! I have already noticed a large reduction in energy. We have a smart meter to I can look at how much energy I used the day before.

I've been using it side by side with a digital usage meter provided by my utility company (SMUD) and it is always within 30 Watts (shows 30W less). Not a scientific test though :).

Thanks very much for the response. After entering my question, I figured out how to fake it myself with what I've got. I just put the cost of electricity at 1.00 per kWh. So now after any amount of time, instead of it telling me how much money I've used each month/year, etc... I just read how many kWh I've used each time period. Sometimes you have to be smarter than the $20 device, but it isn't always easy. :)

Measure the power consumption with something such as Kill-a-watt. Indeed a better design should've left a visible window.

Based on a definition I found on line that follows Meter An electric demand meter measures electricity usage over periods of 15 minutes on a dial, with the highest rate of electricity usage over a 15 minute period recorded by the meter. The highest kilowatt use over a 15 minute period during a billing period is recorded until a meter reader resets the electric demand meter. Based on that the meter dial is moving just like a regular meter does, the unit should work. It reads the black dial portion of the dial every time it passes and the more power used the faster the dial goes and the unit calculates the usage based on that and the information you input at set up. I don't use mine to get total usage or dollars, I use it to monitor the usage peaks and to find out what is running and if it should be etc. I doubt that you would get as good a reading as a meter I don't believe this unit to be that precise, but if you are just trying to get an idea of the usage it should work. If you need more of a precise answer, I'd contact Black and Decker. Hope this helps.

Yes /plus kwh or unit cost per day, week, or month. I would recommend. I have 1 on my 5th wheel and it is just what I wanted. The customber can,t cheat you with the amount of electric you use, or they use. if the meter. I brought the the meter that you set .8C or any amount plus cent or amount, that will give you a true amount of cost once you set it. You will get a actuit KWH total cost that they pay or you pay. I have my unit set weekly, it let you know what week it is (25-26-27-28 etc)... You won't be sorry! Tom D

I have had mine for over a year and never noticed a thing. Honestly no difference in my electric bill if it runs or not and I have it running a lot. I highly recommend it!

There is a timer, but it just counts how long you have been measuring your electrical usage.

Very little. We live in a total electric home and noticed little change in our cost. Very efficient, also.

I don't know how much power's consumed by it when not charging, but I leave it plugged in for easy charging. My guess is probably not as much as an alarm clock though.

Yes. the watt button gives you instantaneous power usage. The KWH kilowatt hour button gives you power consumption over time. For example, keep your refrigerator on it for 24 hours tells you how much power it uses on a typical day. The meter doesn't have batteries. It uses a small amount of current to operate. a power loss would lose the measurement.

Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight. While using an internal Seagate 500GB hard drive the meter shows usage is 5 Watts and .07 amp draw. The figures are different from one electric provider to the next. As an example, my local electric company charges me 12 cents per kWh during peak season and 11 cents during off peak season. It's costing me $5.26 per/year running 24/7/365.It's been running flawlessly since December 25, 2012. Yes, over a year and I share family pictures to lots of family members. Very easy to use.I hope this helps.Thanks,Terry Mundy Hi Mr. Hogan,I installed a Kill-A-Watt from Radio Shack tonight.

It is a useful tool. However, more neighborhoods are getting upgraded meters that can provide this information. Check with your utility. Wandering round the house with the display, switching things on and off gives you a great sense of what is consuming power and whether you can or want to do anything about it. I was surprised, for example, just how much power was still used by my subwoofer when the stereo was off.
