Anyone here have experience with this product? I've been searching for reviews and such, but do not find many.
Their is a $500 tax credit, so I am giving it a try. I got a new unit on ebay from a distributor for about $200 less then they sell it on their site, so when it arrives on monday, I will hook it up and plug in my testers, give it a wirl, see what my lines power factor is and total wattage/amperage running some AC Units, a few Trintron monitors, fridge, toaster oven and cloths dryer ^_^
Sounds like a cap bank to me. It states that the unit stores "reactive power".
Large electricity users with loads that draw a huge starting current can benefit by using them to correct the power factor and answer demand current during load start-up. Industrial electric utility customers are generally charged not only based on K-watts consumed, but also based on peak demand, as determined by a demand meter which monitors for large starting currents. These starting currents represent reactive power, but nonetheless result in real power losses throughout the utility's infrastructure as copper losses, requiring larger sized transformers and conductors throughout the infrastructure.
I seriously doubt that the typical homeowner could benefit from such a device, as the homeowner really doesn't have highly inductive loads to start. I wouldn't qualify a central AC unit or a refrigerator as a highly inductive load. At least tno compared to the types of loads that the utility companies worry about.
On the other hand, it could be a power-factor correcting inverter, that makes the load of your house, no matter what the overall power factor may be, look pretty much like a unity power factor to the utility. I still don't see it saving the homeowner much, as the typical house is pretty close to a unity power factor already - motor loads do make it slightly lagging, but I would think to not much more that 0.8 or 0.9. -- Is there anybody out there?
I put a green plug on my grandmothers old freezer years ago, and her monthly bill dropped about $60.
Inductive loads would be motors correct? Things like electric water heaters, what would that be?
didnt they stop making those "green plugs" because of the fire risks involved ? i had a few of them, they arent really anything short of a high current variac/triac circuit. the ones i had, i modified with better heat sinks to help dissipate the heat. there was also a "running" voltage calibration control which i set to a lesser voltage than what it was set at, i think 109v from 119. they work, but dont expect a refrigerator or a/c unit to work any better with it. they work great for motors, increasing the current supplied if needed, sort of like a regulation circuit, only using needed current to get the "job" done. -- S.C.P.D.

If it increased the power factor, then it may help me out a bit.
Checked the PF on my 5k btu window AC in my bedroom, and it runs with the PF fluctuating between .78 and .85 It is also a high efficency AC. Although, it runs with that PF, it uses a sustained 354watts of power.
My TV runs with a PF of .88 and uses 120 watts. My trintron uses 200-ish watts, fluctuates Greatly, and the PF is .60
The full size high efficency fridge in the kitchen, has a PF of .92 and uses 100 watts when the compressor is running, and 130 watts when the door is open and the light is on.
I could not test the dryer, as it is 240v 40 amp, but I'm sure it sucks pleanty :P
I will hopefully find out monday or tuesday if the device works or not, if my meters dont measure properly with it on, then I will have to wait until my next bill. We have been using the AC's quite a bit with this heat, MUCH more power used then last month. So if our bill is similiar, lower, or real close, then it works! -- Do the Do!
Any which way, I emailed the NASA contact for logo useage, to check on that.
I call BS. Besides, PFC is a EU thing that has never been an issue in the US, unless maybe you have a demand meter. Unlikely as those are usually only for a bussiness. Not to mention that a UL listing means little, if it atleast had an ETL, CE, or even better a TUV listing, I might think otherwise.
That other site looks a bit questionable, as was pointed out, with their generous use of logos.
Aside from the fact that what they call a DOE report which supposedly supports the concept of their product is working with 100's of Kw's I think the key words in the report are "capacitor suppliers and engineering firms can provide the assistance you may need to determine the optimum power correction factor and to correctly locate and install capacitors in your electrical system."
As such just buying a box of caps and connecting it to the breaker panel may or may not have a positive effect on ones electric bill.

No, wife and myself own a nail and hair salon I will be test it on monday night if it comes on time, DHL seems to have delayed shipment along one of the stopps
I'm installing this in my home first, give er a try, if it works, i'm going to move it to our shoppe, which uses quite a bit of electric. Air brush compressors, hair dryers, 80 gallon electric water heater, capichino machine, tv's, 4 ton AC unit with a 90,000 btu furnace, and exhaust fans up the wazoo
even if it saves 4-5% on my bill, that means I will have it paid for in 6 months with the savings (We have 200 amp service, and at times, use quite a bit of it with the Ac and water heater running) -- Do the Do!
Brand new buildout that was completed the beginning of the summer. This is a business I am talking about, not my house.
80 Gallon high recovery rate electric water heater- the building is condo'd out, and the association wouldnt let us put more holes through to the outside, so we had to do electric. on top of needing electric, we need high recovery rate to compensate for the high use of hot water we have.
4 ton AC, it gets very hot in here with all the people, equipment, hair dryers, and other missl equipment we have. 90,000 btu furnace is gas luckly, but it has one big blower to move the air around the shoppe.
on the contrary, we have a new high efficency AC unit, high Efficency furnace, and a High Efficency Water Heater, but electric water heaters, especially high recovery rate, use a lot of power!.
I also forgot about the Capichino machine, that has it's own built in water heater. I keep the water heater and capichino machine on timers, to turn on 20 minutes before the shoppe opens and shut off 30 minutes before we close.
The water heater is very insulated. I heated it up to test it a week before our grand opening, I shut it off once the test was over, and 5 days later, the water was still warm. Not hot, but useable!.
Point i'm trying to get accross, is that Businesses use A LOT OF REASOURCES! ^_^ -- Do the Do!
Interesting news review: This is for the KVAR unit, which is the same as the power save 1200
Interesting vid, thanks.
I had to look up the patent claim since (as bad as our patent office is and it is ) I could not see how you could get a patent on power factor correction. The patent is is for (quoting the patent) "it is an object of this invention to provide an apparatus and method of use to determine capacitance required to optimize power factor in single phase installations" it's here if anybody is interested.
Hopefully it will arrive today. The seller used DHL, and to reduce shipping costs (I have no argument against that), used some strange DHL method of shipping, that goes ground accross the us (From Cali to Wisconsin), then once it gets here, it gets dropped off at the county's main Post Office (by Mitchell Int. Airport), then gets transfered to my local post office, then delivered by the mail carrier. Takes longer, harder to determine exact date of delivery But she said projected is today, so, pray :P ^_^ -- Do the Do!
i thin, though i'm not sure, that most appliances in the home have passive power correction built in. i'm almost positive refrigerators do, and pretty sure the fan in furnaces do, pretty sure that attic fans do not, same with most if not all plug in fans and maybe ceiling fans. and, interestingly enough, i have no idea if the residential AC compressor motor and cooling fan are power corrected. would be nice if they were... BUT, i don't think our power bill takes PC into account, so i don't think it would save us any money to have it. -- A man compounded of law and gospel is able to cheat a whole country with his religion and then destroy them under color of law. -Ben Franklin
i just got hit with a 4 day ups delay on the last part i need for a water system re-pipe. the tracking page says it was a train delay. the delay seems to only have been a day, not sure how that translates into 4 days later....
i also just had a dhl delivery of some house insulation material. they left it outside the front door, my guess is because they had punctured the material in a couple places and didn't want to get in an argument while on the route. pthpt. -- A man compounded of law and gospel is able to cheat a whole country with his religion and then destroy them under color of law. -Ben Franklin
