Hello everyone,
I am trying to build a motorless generator that is a self contained and self powered that is not fuel consuming. We have made the switch to off-grid living at my fiances home due to outdated wiring in the home not passing inspection(power shut off a couple years ago and not living there ourselves but might move back if this could work), so I want to use what I already have, if possible, to create a generator for typical house usages.
What I have is a 12v 5000w/10000w peak Inverter with 4 115v 3.33a outlets, that I am assuming came out of a long haul truck, that was purchased on a secondhand website; a power supply battery backup(much like APC products) that is for medical equipment that has a 12v battery for backup supply and 4 120v outlets, also with data monitoring connections that I won't be using; also an automotive 12v battery, if needed.
My idea is that the battery from the backup can be removed and use the wires from the battery charging supply to feed to the 12v inverter that has the power supply backup plugged in one of the outlets of said inverter. So in essence, the inverter is powered by the 12v battery powersupply that is powered by the same inverter it "charges"
I know that a battery charging system is usually higher than the battery it charges so I want to know if doing this if it will damage either the inverter or the powersupply or should I add a component such as a capacitor or a resistor, if needed? Each component has not been modified in any way, I just had them sitting around and wanted to see what I could come up with for basic usage to power a phone charger when needed or small appliance in the home. Thanks for any suggestions!

 

You are a genius, not.
Sorry, Mother Nature doesn't allow a free lunch.
That's an over-unity perpetual-motion device which can't work since it has no source of power.
If that scheme would work, we won't need electrical power plants, or solar panels, or wind generators, would we?

 

 

You are not the first, and won’t be the last.

Your plan will work - the battery will run the inverter to run the charger to charge the battery.

As device operates it will of course get warm to some extent. That warmth is energy extracted from the battery, so the battery will gradually lose charge.

What you are making is a very complex battery-powered heater. Is that what you want?

 

Welcome to AAC.

The most fundamental laws of physics make getting more out than you put in is impossible. Worse, there are always losses so you can’t even get out as much as you put in.

This idea—something for nothing—is generally called “over-unity” and is a prohibited topic on AAC. Unfortunately, it seems most prudent to close this thread.

If you have questions about practical power systems as a solution to your problem please don’t hesitate to start a new thread.
