HIGH VOLTAGE CAN KILL! USE RUBBER GLOVES WHEN WORKING WITH ANY HIGH VOLTAGE AND ACID BATTERIES.
Just because it is your project don't assume anything, be safe! it only takes one mistake and your DEAD!
I'll say it again!
ONE MISTAKE AND YOUR DEAD! USE RUBBER GLOVES!
USE HIGH VOLTAGE WARNING SIGNS!
Place these signs at every entrance of your project area!
KEEP OUT OF THE REACH OF CHILDREN AND ADULTS. COVER ALL BATTERY TERMINALS WITH RUBBER OR ANY OTHER NON CONDUCTIVE MATERIAL. MISTAKES CAN HAPPEN.
PLEASE BE CAREFUL!
Please note that 120 volts dc can not be used for house current until it is changed to AC. but you can run any ac light bulb(s) with it, and some 1500 watt space heaters.

What is an inverter? An inverter steps up a DC incoming voltage from a 12 volt DC battery and converts it to 115 VAC which can be modified using special techniques to convert it to house hold sine wave current.
The Hertz output is adjustable, you can easily adjust it to a common household 60 Hz. Or for science experiments you can raise the hertz to any desired amount by simply speeding up the small dc motor which you will be using along with our commutator switches that we invented. Most inverters sold today have an output of 115 volts ac and the cheap invertors are not sine wave at all. Our invention uses much less amperage from the battery than other commercial models. That means your 12 volt battery or battery bank will last longer. Never let your battery bank go under a 25 discharge, they will last much longer and save you money!
Building a large watt inverter is not extremely simple but if you take your time and do it right you can save thousands of dollars and you will be learning also. Of course for us it is easy, but once you get the hang of it you can build more for your own use only! If you wish to manufacture them you must first get our approval! There is another option to building a 5,000 watt inverter, you can simply connect ten 12 volt deep cycle marine batteries in series as shown below. This can be very dangerous so extreme caution must be taken! This method eliminates the need to step up the 12 vdc to 120 vdc and you get much more wattage, 10,000 to 15,000 watts. The 120 vdc is then converted to AC by using our simple commutator invention, which should be included with these plans. Remember to use the proper wire rating for DC and AC. The wire for the batteries must be very large gauge to handle the wattage, it is multi strand wire and together make up about a Vi diameter or more. Make sure your wire is as short as possible when connecting batteries together. I have never tried it but it seems it would be a very good idea to use a 10 to 20 amp circuit breaker between your #5 and #6 batteries, this is for safety just in case you get a short some where. You should be able to find large gauge DC battery wire at a automotive parts store or Solar Supply house or a local multi store that sells batteries. If you try to use to small of wire it will limit your wattage output. WARNING! Make sure all connections are very tight and then paint them with rubber brush-on electrical tape by North American Oil Co. Atlanta GA. (Hardware stores.) Keep out of reach from anyone!
