efergy Elite-Max Display Kit 7.9″ Color Energy Monitor No WiFi Required. Data Download Direct from The Monitor

Unbelievable product - will pay for itself fast! Will work with solar but have to know limits of monitor and how to install. You must remember the sending units for this monitor work on an electrical principal of magnetic fields. When electricity moves through a wire it produces a magnetic field. BUT only AC current. As the electricity moves back and forth (AC means 'alternating current') the magnetic field is generated. If you install the sending unit on a power cord from say a freezer then you have "two" lines of AC current. As the electricity moves back and forth through two lines they cancel each other out. No magnetic field for the sending unit to find. Must install on one line which means finding the line in your breaker box. For DC (DC means 'direct current') the electricity moving through the line does not generate a magnetic field thus the monitor will not work on DC. Electricity from solar panels is DC.So how do you use this monitor on solar installations? I have a 7.2 kW grid tied solar array. All grid tied solar arrays have an inverter that changes the DC current to AC current. Find that circuit where it ties to the grid. This is likely near your power meter. Install the monitor sensors at that point. Will provide wattage generated by the solar array.I purchased this monitor after my local power company installed a new meter to track my total power consumption and of course send me bills. For over 3 years I have monitored my power consumption closely to ensure the power from my solar array was accounted for. After the new power company meter, my power consumption tripled. I could not find why. After installing the Efergy Monitor on my solar array circuit I found one third of my array was not working. Trouble shooting the array produced damaged insulation on a wire that shorted out that section of array. Fixed and power produced back to normal. Save big bucks there with the help of the monitor. However power consumption still high.I noticed my old upright freezer working a lot. So I installed monitor on circuit to freezer. This required finding circuit to freezer in the breaker box in house. Turned out freezer was consuming way more power than specifications say. Removed freezer and found damage so replaced. Helped a lot on power. Monitor saved more money.Began to monitor HVAC system. HVAC use 220V so installed both monitor sensors on the circuit to HVAC. This circuit in the same breaker box as freezer. Discovered HVAC using correct wattage when running. Monitored over several days and found HVAC running 15 hours per 24 hour day. This was way too much. Called a HVAC contractor and discovered leak in HVAC coolant system. Covered under warranty. Now HVAC runs maybe 4 hours per 24 hour day. Saved a lot of money this time.So how do you know how long something runs? Install the monitor and when an item like a freezer or HVAC is running write down the wattage from monitor. Do this a dozen or so times. Average your data to get the average wattage when running. At the end of a 24 hour day write down the total wattage used by the item and divide by the average. This will give you the number of hours of run time. I set the clock on my monitor to reset at 7:00 am instead of midnight. Makes it easier to read numbers instead of getting up at midnight.Installation in a breaker box is simple but as many reviewers say, if you are uncomfortable with this get help. I did install mine and replaced the box cover. Sending unit transmits just fine though the metal cover. I used a hand held clamp on multimeter to spot check numbers from the Efergy Monitor. It was always very close. I installed the sensors and monitor over a month ago. No problems with AA batteries.My only complaint is the 'historical' data gives total since last reset with is midnight or what ever time you tell it midnight is. Remember I have mine set at 7:00. So if you don't get your previous day's data before it resets you will miss that information. The monitor display shows humidity but I don't believe the numbers. Without some sort of humidity device I think this monitor just estimates humidity from temperature.Summary: This thing works. It is very versatile. Installs easy. Easy to program. If you think through how your circuits are wired can be used to monitor many devises. Monitor is very sensitive - right now showing my HVAC thermostat is using 0.011 watts. I've recommended to others have purchased.

After surveying the alternatives i picked Efergy as the vendor I would be happy with any of the Efergy models.All the vendors need to clip a Current Transformer (CT) pair around the two 120v main leads coming in to get good readings and this one also does.What Efergy does that I saw nowhere else was have a tiny external battery transmitter connected to the CT pair. The cleanest contact with your electrical panel.Everyone else has way more gear/wire next to the electrical panel and some with transmission issues also. I want the minimum wiring and plug-ins around my electrical panel - don't you!! I want to do the minimum around killer voltage/current levels and i want a clean finished result around the electrical panel and not a big question mark, "what's this?!" plugged in externally and connected to what is inside the hot electrical panel. Oh, and for those vendors that have "transmission issues", No, i am not going back to fiddle with anything around the electrical panel, thanks.As you are reading this now, wanting high quality data that you control and are ok with more effort around the electrical panel, stay tuned - Efergy delivers on the data quality too.So, the good news above on the part of solution around the electrical panel. Here's more detail and focus on that. After all it's the two ~1/2 inch diameter hot 120v lines coming into the electrical panel. Detail and focus here is a good idea.A main breaker inside the panel does not shut off power to the 120v leads coming in, just the distribution from those leads. If you have a shutoff for the 120v leads coming in it will be back upstream where the meter is.I installed my current transformer pair on the 120v leads while they were "hot" and I had no main shutoff inside the electrical panel either so they were also "hot".So, i had rubber tennis shoes on, rubber dishwashing gloves on.I removed the electrical panel cover over the circuit breakers - the three big leads coming in to the panel - two 120v leads and one neutral line.So, the objective at this point is perform two clip current transformers around two hot 120v lines, the single lead needs to exit the box (somehow), then put the electrical panel back on, then plug in the wire lead to transmitter, and this key part of the installation is done!!ok, if you were paying attention there are two details above that i skipped.first you need to mount the tiny transmitter. At least as a short term solution get some double sided tape and secure it to the wall or shelf within reach of the wire that will plug into it coming from the current transformers inside the electrical panel.second, figure out how that wire is going to exit the electrical panel. I cheated and decided to not screw down the electrical panel covering the breakers tightly to leave a tiny gap there to allow the wire to get out. The better way would be to use an available panel knockout inside the case provided for the hot wire conduit connects and then punch through your drywall outside the panel.ok back to the actual clipping operation in which you are holding your breath that nothing bad happens.- make sure clip the two 120v lines - not the one neutral line- make sure you have good clearance to clip and how the clip is going to reside in the case after you clip.- when you clip be aware of the one line that will be exiting the case.- what would happen if the line coming out dropped out of your hand and made contact with a live wire?!I have to thank efergy on this - you will notice the metal plug that will go into the transmitter is covered with a little plastic cover - to be removed only when you are ready to plug it into the transmitter. If they hadn't covered that and you dropped it onto a live wire - guess what ??!! I suggest you tape that with electrical tape temporarily to the wall before your clipping operation so your two hands only need to hold the two clips destined for the two hot 120v lines. so you have your transmitter secured and your wire temporarily secured leaving your hands needing only to do two quick clip operations on hot then put the electrical panel back on.Now you are safe, relax, the important stuff is done. Few simple operations and you are seeing live data coming to your wireless display. A few more steps and as i recall a day of delay and he data collect is available online 24hr/daily/monthly.graphed quite nicely. Also for the folks like me who want their data. You can download 1 minute interval data into an excelbelow is an example - you will get an excell file for each month with thousands of reading, one per minute if you want the highest resolution.As folks have commented, the display device is great for walking around turning things on/off and seeing the usage change.Timestamp Power (kWm)3/1/2014 19:26 2.763/1/2014 19:27 4.783/1/2014 19:28 5.853/1/2014 19:29 5.333/1/2014 19:30 2.78I hesitated for a long time thinking i wanted individual readings for separate circuits. There is nothing preventing you from buying another to allow you to play with the analyzing a specific circuit. you are going to want whole house anyway and once you are familiar with one minute usage changes and whole house usage, oh I left the stove on, oh, i left the space heater on, oh the dining room light are on, oh the a/c is running a lot check the thermostat settings. So just buy it, get it going. stop analyzing which one to buy and start looking at what is using electricity.(note: if you live in an apartment or condo it's possible you do not have standard residential 120v/240 service and you have 120v/208 service which is not compatible so check that.

I bought the Efergy Elite Wireless monitor to monitor how much energy my geo system is using. (My geo is not on a separate meter since the benefits wouldn't out weight the costs with my power company). I used the Efergy to monitor how much energy my Geo system used. I now have it monitoring my buddie's Geo system (same size and brand) as a data comparison to my unit.It took me some time to get it set up right. I'm no electrician. After some trial and error, I connected the probe correctly in the breaker box and was getting accurate readings. The directions and documentation are very poor, but once you figure the system out with trial and error, it's simple to use and monitor your energy use.I bought the "P3 International P4400 Kill A Watt Electricity Usage Monitor" for my smaller plug in appliances (and love it), but needed the Efergy for my 240 circuits.I would recommend this product.

Works great. Pairing was a snap. However, the setup manual leaves something to be desired. Needs work. Once it's all set it works great and would recommend for any RV'r that wants know their power usage.

I have used an inferiour make for a few years on my EV charger which broke and I found this. I can not believe how easy it was to install, pair and set up. It just worked! A very good, detailed manual and an equally easy single page with abbreviated installation instructions. This is now on my recomended list for other users. Thank you.
