Save Money, Save Energy





“The adequacy of North America’s electricity system will decline unless changes are made soon…. Demand for electricity is expected to increase over the next ten years by 19 percent in the U.S., but confirmed power capacity will only increase by 6 percent.” - North American Electric Reliability Council (NERC)

“Over $16 billion dollars of electricity is unusable energy, but billable in the U.S.” - U.S. Department of Energy

Up to 25% of the billable electricity consumed in homes and businesses is nonproductive and unusable. Most AC motors operate at 80% efficiency under full load…. The efficiency drops dramatically at lower loads. This non-productive energy wastes money and also shortens the life of inductive equipment such as motors, HVAC equipment, pumps and major appliances.

Electricity is measured in units of power called watts. It was named to honor James Watt, the inventor of the steam engine. One watt is a very small amount of power. It would require nearly 750 watts to equal one horsepower. A kilowatt represents 1,000 watts. A kilowatt=hour is equal to the energy of 1,000 watts working for one hour. The amount of electricity a power plant generates or a customer uses over a period of time is measured in kilowatt hours (kwh). Kilowatt hours are determined by multiplying the number of kw’s required by the number of hours of use. For example, if you use a 40 watt light bulb 5 hours a day, you have used 200 watts of power, or .2 kilowatt hours of electrical energy. This article is from
How do the power companies bill us? Simply said, they bill us for the kWh’s based on the highest 15 or 30 minute demand period during the monthly billing cycle . Each power company may have different demand period.

How can I start saving money now?

By installing the KW Sentry® in your home today.

How does the KW Sentry® lower my electric bill?

The KW Sentry® optimizes the electrical power that comes into your home allowing your appliances and equipment motors to operate more efficiently. This in turn helps lower your electric bill.

How does the KW Sentry® green box work?

In laymen’s terms the unit has capacitors inside that store electricity as it comes from your electric company much like the battery in your car that stores electric energy which it gets from your alternator. As your heavy duty appliances and motors are plugged into your household electrical system, the demand for power is sent to your KW Sentry® unit and it releases only what is needed to satisfy that demand. That means little or no waste. As the motors operate, reactive power is pulled and pushed to and from the KW Sentry® unit at 60 cycles per second by the motor’s demand for power. This whole process is called “energy optimization” or fine tuning your electric system like you would tune up your car to increase your gas mileage. The KW Sentry® unit has fourteen United States and International Patents. For more technical details see ourwebsite.

How has this technology been proven?

This technology has been tested by the US Dept. of Energy, Underwriters Laboratory, Canadian Standards Assoc., NASA, and Honeywell. Each one of these entities has performed extensive testing on our units and has certified that it is safe and efficient to use. Our certifications include: US Patent, UL listed, ROHS compliant, NASA tested and approved, US Green Building Council, CSA and most importantly the thousands of home and business owners that own KW Sentry® units and are
realizing savings.

I just wanted to thank you for introducing me to the KW Sentry® box. The neighborhood I live in is all electric so my electricity bill is outrageous. I was really excited to try the KW Sentry® box not only to lower my monthly electric bill but as a first step in going “green”. After the quick and simple installation I anxiously awaited the next months bill. I was so pleased to find that my bill had gone down substantially, from $406 to $238. I am excited to see my next bill! I would recommend this product to everyone, not only for your pocket book it’s good for the planet!
- Angelee B., Providence, TX

The power consumption in my home has been drastically reduced since installing the KW Sentry® unit . My last three bills were down from an average of $130 per month to $93, $73, and $77 for February 2008 and is currently on schedule for about $77 for the current month. I installed the unit in February 2008. My home is over 30 years old and has a three year old A/C compressor and a 7 year old heating unit. I have several neighbors who have decided to put one on their house after hearing my results. I am anxious to see what savings they will get also. - Cathy F., Owner/Manager,
Cedar Creek Manor

I had the KW Sentry® system installed at my 2500 sq. ft.residence in Yucca Valley, CA in mid August of 2007. My first bill after installation was over $100 less than the previous bill. The next bill was the first one that was entirely on the KW Sentry® system. Versus the same billing period last year, I used 29,69% less units of energy. That’s a lot of savings! With the economy being the way it is this year, the KW Sentry® system may be the best financial decision I’ve made all year. - Stephen A.
