Goldmine of parts.

The place were I work asked me to haul this off, its been setting in the warehouse

collecting dust. nobody knew what it was, the only thing they did know,it was in

the building when they bought it and were tired of looking at it.

Two battery boxes,both had 600 volt 200 amp DC disconnect switches

large one had 24 AGM 12 volt battery's, Small one had 10.





Power supply, don't know what it was used for, has a transformer that is about 12" by 12" Copper wound square wire, this thing weighed about 150lbs.





Inverter/charger, I think.

It also has a very large Transformer, 19" by 18" also wound with large gage square copper wire. guessing the hole thing weighed 300 pounds+

Then I have all these battery, I'm sure they are junk, battery's dated Oct 1997.

had to unload the battery boxes just to load the cases on the trailer.

I think it was a good haul, lots of cables, copper, very large heat sinks and other Misc.

Now I have a box to put my battery's in.

[donald77777]

nice haul. lol you should test the batteries and see what they give you. If nothing the scrap value would be a nice hunk of change.

[MattM]

Looks like a UPS for servers or printing stations from an office.

[zapmk]

Ya, checked the battery's this morning, no juice at all left in them at all

sides are bulging real bad. 32 battery's in all, scrap prices around here

is about 5 bucks a battery, put a nickel or two in the pocket.:>)

[zapmk]

ya,Looked like there was a big server room at one time in the warehouse.

[zapmk]

Going to scrap out the transformers for the copper I think, inless I can find another

use for them.

Taking the DC disconnect out of the smaller battery box and put it in the big one,

already have a bank of 12 T105s, thinking about two banks of 12 now.

Some nice big heat sinks in them with some kind of diodes marked:

Semikron SKKT 91/06E IGT-3 need to find out what these are,

couldn't find anything about them on Google.

Yes, it is a UPS.  I saw a few similar to that pulled out of service from a hospital.  It is a good haul.  I had to pass on some a few weeks ago as I had no way to move them.

Batteries are likely junk; even if they have "some" life- they were designed to remain on a float charge until needed, where they would be subjected to heavy current draw, and then replaced after the event, or replaced after a fixed period of time on float.  They have less flexibility in charge and discharge than regular car batteries.  If they do hold a charge for extended periods you might try them at least for a little while, but don't expect too much from them.  they will likely not desulphate as they are of a design that notoriously does not desulphate well in the smaller packages.

Heavy and expensive best describe the batteries.

You might want to search for a manual for it before you dismantle further, you may find easily adaptable inverters, and system monitor circuits, and left intact, you can trace the installation to easier adapt it to your use.  That transformer alone looks like it could be the basis for a decent inverter project in itself.

Hi Zapmk,

The picture showing EPE FPS-1000 and the key pad is an Uninteruptible Power Supply. We have just de-commisionned one at work. The back up side of ours consisted of 4 x 12VDC batteries in series for 48VDC. If it still works it would be a very good start to a RE system. i.e. it can be used as an inverter when powered by your 48VDC battery bank. The added bonus is you could top up your batteries with the built in charger if you had too assuming your are not running a huge battery bank. If I remember correctly the AC wave out of it was decent and the unit was rated at 4KVA. The display is also nice showing volts/amps/freq etc... in and out and it could be mounted remotely. (Check if yours can be removed, ours was just plugged in)

I will check tomorrow to see if there might still be a manual floating around if you need it.

Tried Googling for a manual, no such luck.

I think I'll hold off from scraping it out for a while.

The battery banks were wired for 120 volt output.

Found a tag:

AC output

Volts: 120/208/240

Amps: 149/84/73

DC input:

Volts: 120

Amps: 151

18. KVA at .83PF
    
1. Phase 60HZ

120vdc front end? cool!

before you part it out, i would think that through very carefully

likely it produces a decent sine wave and the front end voltage is managable

i got a 15kva ups with a 240 vdc front end, which i am not going to use as is

because of the very high and dangerous dc voltage needed.

like i said, think long and hard before you scrap it for copper and parts

someone would likely really like to have it and be willing to give you a fair price for it as well.

and if you can find the manual, do so!

i could not get the one for mine, and called exide to get one

ya right.... 1800 bucks plus shipping!!!

i sure would make every effort to make it work as an inverter

the ability for 3phase output is a huge plus also, opens up a whole nother

market in my opinion.

Man, that would be great if I could get a hold of a manual.

[zapmk]

Hi bob,

I hear what you saying, right now I have a pretty good system setup already for 24 volts with Outback inverters.

The only thing I was really interested in at the time was the battery boxes for my system. I'd really hate to scrap out something that could be useful to others.

Don't know if this thing even works, the internals look good, I guess I could wire a bank of battery's together and test it.

[DanG]

The only hitch I see is the difference between input and output - 240 watts.

[bob g]

my bet is it works just fine

the batteries probably died of old age and the unit then shut itself down

many of the big units run the mains to keep the unit charged and the inverter runs all the time to provide very stable and clean power.

it would be a really nice addition to an offgrid shop where 3 phase was needed

and all you had was a single phase genset to keep it charged.

if i didn't have so much on my plate now and could afford the shipping i would make an offer to you for it.

That's the first "I found this" posting I've seen since that beats my AGM stack discovery last summer.  Congratulationss!
