Does this system do power factor corrections for each AC circuit being monitored?

Thought I do not know what the software in the in-panel measurement system is doing, with only a current transformer on each circuit, I can see no way the current/voltage phase relationship on individual circuits can be measured. The voltage is only measured on the panel as a whole. I have been impressed that the system can track the phase shifts needed to track solar panel power put out on the grid accurately. I can cross check the eMonitor solar power measurement using a measurement system supplied by the grid tie inverter manufacturer, SunPower. The discrepency is usually under 2% and much of that results from the measurement cycle with the eMonitor measuring every minute and the SunPower system measuring every 5 minutes.

Have looked at this product for about 5 minutes but would assume they use 120V as a voltage constant. Voltage transformers for monitoring power usually have a secondary of 120V anyways.No there will be no power factor correction with this item, all those products that claim to correct power factor are blowing smoke. You are charged a kilowatt rate at your house, so does not matter what your power factor is your KW usage will remain the same.

No, it only acts as a switch to control one of the two outlets, based on the commands of the controller. Amount of Watts used is not tracked by this device.

They have power supply calculators just do a search they are pretty accurate

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.

Frankly I dont know as I never use it, And my manual doesnt really go into great detail?, But there is a line that says : "Plug the Red Terminal into the Output to block the DC when you want to test AC Only!. 'Outerwise its a Nice tester and in my opionion its a real steal at this price as i am very well satisfied with mine but again to each his own!. Hope this helps: BEST WISHES!.....

If you are asking if it has the ability to measure AC with a DC offset, then yes. You can choose to filter out the DC component (leaving only the AC wave form voltage difference), or keep it in, leaving the AC waveform elevated over ground with the appropriate DC voltage difference. This is what I believe you are looking to do. The company offers a copy of the software on their site which you can use in a demo mode to see the interface you will be working with. Somewhat related, you can also generate an AC waveform with a DC offset.

No. It is powered by the circuit voltage. It will tell if the Hot and Neutral are on the correct terminals.

It does but the unit I purchased created a back feed of current into my monitors damaging a tv.

I use one of these myself, and yes every PSU has to be plugged in to an ac outlet.

so far it doesnt seem to matter/ i ran it on 12 and 24 volts dc>but i have NOT tried IT ON AC?

I don't believe so. As far as I know, it records and displays current readings only.

it can give instantaneous readouts so just have somone watch it while applying your peak load, you can also see what voltage your outlet is deliveringa and at what frequency, not all outlets are equal and power company delivery can be uneven.

It will monitor total wattage. But you will know how much each individual device consume once you turn it on.

Not to my knowledge. The outlet converters are all on different frequency's. I bought a few more from Home Depot that I liked better than this. It had an on/off button and it showed on the package what frequency they were on. When I bought my second AmerTac it was the same frequency & set off the other outlet upstairs- not what I wanted it to do. Good luck!

yes I have three of them to read each inverter and one to read total from all of my inverters.

I believe it can measure 120, 240 or three phase power. It comes with TWO current probes.If you only attach ONE and restart I believe it will measure 120 volt single phase. However, if that is all you want to do , buy a Watt Wizard for much less money.

It's just a capacitor farad measurement tool. I don't think your results will be very accurate in-circuit.
