| Re: Power Save 1200 ----Any one have experience this product? 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.
