Easily turn an old UPS into a power inverter. FREE AIR CONDITIONING

[@murraymadness4674]

Free? where do you get free 12v for the batteries?

[@kalukalinx]

Many hours can it work on

[@TitomnJeswen]

How does it make it free? You still need power to charge the batteries.

[@ThriftStoreHacker]

I have some solar panels to charge the batteries. They charge up all day and i can run the A/C for a couple hours when it is really hot out. It really helps with the power bill. If i had more solar and more batteries i would run it all day.

[@TitomnJeswen]

That's nice.

[@cyrusramsey923]

ThriftStore Hacker where do you connect the solar panel? Is there a way to bypass the AC cord to accept solar DC to charge the battery as the UPS must have a charge controller to the battery? Or do you still need to purchase a solar charge controller and connect to the battery terminals and use the UPS outlets as an inverter? Thanks

[@ThriftStoreHacker]

Cyrus Ramsey I use panels and a controller hooked to the battery. the UPS is used because it is a cheap or free way to get a power inverter. I'm currently looking for a cheap gas or diesel engine to turn an alternator. if I find all the bits over the winter I will be able to power more than the a/c

[@GeekBoy03]

Wind generator a lot cheaper, and you can get quite ones.

[@stresslessmoney4585]

Can this ups carry rework station

[@timabbott9101]

I have an XS-1500 with bad batteries - Removed the batteries (7.5 Amp-Hr) and connected two 55 Amp-Hr sealed lead acid batteries to it, works like a charm. Kept the computer / network / LED TV and several LED lights going for over 20 hrs. during hurricane Matthew

[@ThriftStoreHacker]

Tim Abbott nice! one thing I would recommend is to add a computer case fan. help ventilate the board. mine runs very hot with the air conditioner running.

[@rahmatdalimin9219]

How long can you run your air-conditioning with this setup!

[@ThriftStoreHacker]

running a bank of two 60 amp hour batteries I can run it for about 2 hours.

[@Flamethatburns]

Before everyone turns into a cowboy and rips their speaker out, when you turn the unit on, push the button twice, and it should silence it. You can also plug it into a computer and download a free program to silence it. You can also put a switch in series with it, to turn it off and on. Put some terminals that go to the battery so that you can put a voltmeter on it to check the battery level, or plug it into your computer to tell you how long you can operate it before charging or changing out the battery. When the battery goes down to a dangerous level where it can be ruined, the speaker will make a continuous noise, so keep that in mind before you silence its ability to tell you something is wrong!

[@obenvaleryparh1042]

This is amazing bro

[@TheHuntermj]

Could you hook up an alternator or solar panels directly to the inverter of a smart ups? How will overpowering or underpowering the ups affect the unit?

[@TheHuntermj]

By underpower I mean the correct voltage input but trying to draw more watts than available, and by overpower I mean correct voltage input but having excess amps avalable from the alternator.

[@ThriftStoreHacker]

Matt Hunter you could use an alternator but you will still want a battery for the alternator to keep the power consistent. the alternator is internally regulated so it will cycle if the battery needs charging.

[@TheHuntermj]

Mainly I wanted to use the UPS as the inverter for a generator, would a normal car battery be ok for the purposes of power smoothing? Also would I be better off getting multiple low wattage ups units or one high wattage one or does it not matter?

[@ThriftStoreHacker]

Matt Hunter a car battery should be fine. just make sure if your inverter runs on 12 or 24v. the one I'm using in the video runs 2 12v batteries making 24v. the higher wattage UPS the better. make sure you add a fan to cool the circuit board.

[@TheHuntermj]

Sweet, cheers mate!

[@xopexindustries]

what would I have to do to get this to power a amplifier for a car audio system that I'm trying to setup in my garage?

[@ThriftStoreHacker]

xopex industries if it is a car amp you can just use a car battery and charger. or a computer power supply

[@xopexindustries]

do I have to have a car battery? can I do it without a battery? if I have to have a battery, would a motorcycle battery or two suffice? and would I be able to charge them with the UPS?

[@ThriftStoreHacker]

xopex industries a motorcycle battery will run it for 20min and I would not charge it with the UPS. if you are doing a car audio setup it is all 12v DC already and the UPS is useless . you can hook up a charger to the motorcycle battery (see my other vids) and get the 12v DC you desire and charging.

[@ThriftStoreHacker]

xopex industries if you look online there are plenty of tutorials on how to use a computer power supply to run 12v devices. if you want no battery and run it off house power this may be the way to go

[@420brent420]

how would it be free you have to charge it

[@ThriftStoreHacker]

Brent Dyson solar panels

[@hugocnx]

Bummer, my UPS doesn't work with batteries anymore. I extended it with extra batteries and it didn't like that. Probably to expensive to repair.

[@ThriftStoreHacker]

You can find UPS units at the thrift store for super cheap. Most of them get donated because the battery died

[@hugocnx]

@@ThriftStoreHacker I think not here in Thailand. And then again it's mostly Zircon over here and I don't trust them with power batteries anymore. Dunno what happened with them; yes, I ruined 2 already. I can give it a try at the bail shop.

[@Hammerjockeyrepair]

i have one of these but an apc. a little bigger, cant wait to get the new batteries installed and also utilize the rear aux battery port for a set of 2 mack batteries! nice for the fridge, router and tv's so when power goes out, theres not even a flicker of power outage, it is steady on!

[@ThriftStoreHacker]

Just make sure you open the APC case and make the cooling better. put some fans on the control board to handle the heat. If you have a 2000w supply make sure to run it under 1500w or lower to get a long life out of the device. Some 12v computer fans do a great job shedding the heat.

[@Hammerjockeyrepair]

ThriftStore Hacker I already cut the holes and installed a fan directly Infront of the transistors! Those puppies get hot enough to BURN an egg 😳

[@michaelnobibux2886]

They're not made for continuous duty at maximum power!!!

[@JoshuaG]

is your ups sinewave ?? thats an awful lot of electric noise

[@ThriftStoreHacker]

joshua gabriel It is a cheap inverter setup. makes a lot of electrical noise but works good. I gave this setup to a friend who lives in the mountains and they now use it when their power goes out during storms.

[@JoshuaG]

+ThriftStore Hacker Well its a good setup , but i suggest buying a sinewave based ups setup especially when your going to use it with appliances like an aircon, it helps work the aircon more efficiently , im sure you can find some of those reasonably priced :) im just doing this to help other people out there that share the same ideas about running electricity for free an living off grid :) hope this helps :)

[@geppb]

hi, how could I disable the internal automatic shutdown timer?

[@ThriftStoreHacker]

Gepp you can plug it into your computer and play with the factory driver utilities. Should be able to out it out.

[@matthewevenson7764]

Very good video bro

[@valentino10108]

so if you replace the two 7amp battery with two 12v 100amp for example,the inverter will accept that??

[@ThriftStoreHacker]

VALENTIN TULUCEANU i usually run this on two 72 amp hour batteries. Just make sure you add some fans to the inverter to keep it cool.

[@jameswoll]

How/where do you connect the fans?

[@ThriftStoreHacker]

jameswoll link two computer fans together so they run on 24v. Cut holes for venting

[@GeekBoy03]

The amperage is a capacity of the battery system which can be pulled from it,. The inverter would be pulling up to 7 amps from the battery, not the batteries pushing x number of amps.

[@2112426gh]

NEAR THE PART THAT CATCHES ON FIRE!!!

[@josepeixoto3384]

free cold? you in the north pole?

[@omarfaruque4756]

ok how long does it continue & does the ups get very hot?

[@ThriftStoreHacker]

omar faruque I ran this for 30 minutes and it got really hot. The UPS doesn't have fans. With proper cooling it can run much longer.

[@francoishollinger7723]

Used an 1500W UPS with integrated fans. Do the job for a months (and more if you don't forger to clean the fans every 6 months to keep proper cooling)

[@arctikbear]

I tried this a while back, wasnt successful. For some reason everytime I turn on the UPS/inverter after hooking it up with my bigger car battery, it switches off again instantly. Despite researching it for a solution, I couldnt find one. If anyone have any idea please share.. NB: the UPS works fine with the original 12v small battery. (I'm guessing the car battery's amp is wasy to large for the UPS)

[@ThriftStoreHacker]

Sam Kipgen the amps should not matter. it may be the startup wattage of the item you have plugged into it.

[@GeekBoy03]

You are probably exceeding the capacity of the inverter of the UPS.

[@kjosr1]

Now if you connect a solar panel to a power inverter you can connect it the batteries for free solar powered air condition..

[@cecilcooper6210]

It sure won't run long.

[@ThriftStoreHacker]

Yeah, it didn't. Lol

[@leemonster6391]

i noticed ur only using one side of ur batteries how do u run anything using ONLY two negative or two positives wires dont u need one positive an one negative to complete a circuit?????

[@ThriftStoreHacker]

Lee Monster this setup is 24v. One positive from one battery, one negative from the other battery, and the open positive is connected to the open negative.

[@arvindbishnoi3662]

very good and nice is video

[@Hammerjockeyrepair]

or you plug into the pc quick and turn the beep off without ripping crap out!

[@a.b.5372]

The inverter cost money and the car batteries cost money. The cold air is not free. Even the air conditioner cost money to buy it some one had to! However, the video was good why throw out something that still works!

[@ThriftStoreHacker]

Scott Shuman Yes. There is startup money involved. You can find these inverters at thrift stores and garage sales for 10 bucks. the smaller ones that run on 12v can be had for almost free. The batteries are best bought remanufactured if you have a local company that does it. My local guy remanufactures batteries and sells them for half the price of new ones with a 2 year warranty. The charging system is where the money goes. I already have 1000w of solar so I can run this box most of the day on the electric trike battery pack. I also have plans for a diesel engine powered charger. I can make it run on waste oils. my projects are never done and are as cheap as possible to build. As I aquire more cheap junk I will come back to this project. Garage sale season is coming. Thanks for watching!

[@a.b.5372]

I reuse everything personally as well. Things cost to much now days.

[@ThriftStoreHacker]

And it makes a fun hobby. You learn a lot.

[@slideshift5371]

it's not free since you need to charge the batteries after

[@immrnoidall]

um..... you are connected to the 2 positive post. i call fake. you have it plugged in .the on battery light isn't on.

[@ThriftStoreHacker]

Those 2 batteries are not the same. one is a u1r and the other is an u1r-7 same battery but the poles are reversed. Those batteries will only run the unit for about 20min but are small and easy to use for a demo. I use two big 60 amp hour wheelchair batteries backed up by a solar rig to run it at home. As for the battery light not being on.. if you hold the power button for 10 or so seconds it shuts the whole inverter off. Since it is not plugged into the wall the only light you see when you turn it on is THE BATTERY LIGHT! Next thing. I run this channel as a hobby for showing off my experiments. Why the hell would i try to scam people. How about asking some questions before you criticize my video?

[@CotyRiddle]

your gonna kill that compressor and motor inside that ac unit with that square wave UPS. youll need to get an UPS that does pure sinewave output

[@lands1459]

i doubt it's square wave. if it's designed for computers, it's gonna be a sine wave.

[@CotyRiddle]

@@lands1459 smps (computer psu fall in this catagory) have no issues witha modified sine wave (Square wave) as they have a bridge rectifier (Full wave) that turns that 115 volts into 170 volts then get bumpped up to around 400 volts dc before it is then switched on and off in the Khz range. you could literally run a computer psu off DC provided you have a high enough voltage. most if not all budget inverters and UPS are modified sine wave (Square wave) with only the really expensive models (akin to the ones used in the it industry for server rooms) do a pure sine wave. do your research. How ever as a side note some spu's with actvie PFC have issues with modified sine wave inverters.

[@lands1459]

@@CotyRiddle That's pretty interesting, never knew the mains was fed into a rectifier right away.

[@CotyRiddle]

@@lands1459 usually it will go through some type of common mode coke and or a differential choke with some x and y capacitors along the way before hitting the rectifier and then being sent to capacitors. go do a readup on how a smps works and the typical layout.

[@CotyRiddle]

@@lands1459 here is this video from DiodeGoneWild. he goes into some of the technical details and everything but the first one he sows during the introductory clearly shows the rectification stage right after the mains input. kzbin.info/www/bejne/mYmXomObZpdneZY if I can recall correctly there is some topolgys that don't have that as the first stage but almost all smps are the same

[@ExStaticBass]

Your going to want some kin of a cooling fan blowing over the heatsinks inside that UPS. Mostly because the inverter in there was never intended to handle that kind of an inductive load. You can get away with a few fans and phone chargers. You could even run a computer for a long time on that setup. The inductance of the compressor of that AC unit is dangerous to attach to that UPS. I mean, I know it was cheap but why brick it if you don't have to? Putting bigger heat sinks in would help too, like from an old computer power supply or something. The one's in there were designed to run for a maximum of five minutes while a computer shuts down. If you do nothing else, keep an extinguisher handy just in case... I want to see more videos, not an obituary... Just be careful man...

[@ThriftStoreHacker]

i am very careful when it comes to AC power. As for the fan idea you are extremely correct. I fried the 1st ups i had due to overheating. I have a different one that is the same make/model and run two large computer fans over the main board. Works pretty good and i use it to run the air conditioner in my shed.

[@alcaponemafia]

[@ronbutler6502]

OK INTERESTING NOT REALLY FREE MUST CHARGE THE BATTERIES CORRECT..TK YOU

[@ThriftStoreHacker]

yes I will need to charge the batteries. currently I have 160w of solar charging for that but if I can get about 1000w I can run the air all day
