power back up

[firewill65]

I just purchased this on ebay.


Xantrex Trace DR1012

Its a 1000watt inverter/charger. I think I got a good deal on it. What do you think? Also, what size battery should I get to run a mag 12 for a few hours? I have a generator for long term power outage but needed something for a few hours incase I'm not home when the power goes off. Thanks

Forgot to add the specs...here they are:

Those are super-sweet units, and you have a basis for a nice solar setup, as well, if you decide to add that later. It's a nice charge controller/inverter, no doubt.

There's a place in Mami (Kendall Area, I believe) named Magnum Teknologies that sells batteries (the right type) and solar stuff.
Their website is at http://www.magnumteknologies.com/

Another is www.sunelec.com, Sun Electronics, near downtown Miami area I think. They also have an eBay presence, eBay ID: sunelec_miami

Enjoy the controller - it's a nice piece of kit!

Oh, BTW, Xantrex has a nice battery / Runtime calculator here:
http://www.xantrex.com/support/howlong.asp

so you know what batteries to get, or what you'll get out of batteries. Make sure you have your batteries away from where you breathe, and do your math on the wiring, ie, you have a 12V charge controller, so you'll need to get either a high amperage single 12V battery, 2 medium amperage 6V batteries in series, 2 24V batteries, in parallel, etc...

Lemme know if you need any assistance.

Did you make sure your mag-drive pump can handle MSW (Modified Sine Wave) AC power before you bought that Xantrex unit? I thought I had read on here before that someone had problems running mag-drives on MSW.

Thanks for the info...I think i'm going to check out magnumteknologies...they have a 415ah 6volt battery for 89 bucks. I figure I'll buy 2 and run them in a series which would give me 415ah at 12volts, according to the runtime calc. It will run the pump for like 18hours.

I read somewhere on here that the mag should handle MSW fine since all it really is a coil and magnet. I have a power conditioner I plug my tv into when im running on generator power..would this clean up the power coming off the inverter? Thanks again for your help!

I don;t think it'll clean it THAT much! it's a difference in the actual waveform, if you were to look at the power signal on an oscilloscope.

415ah should work great. just remember: in series, add the voltage, in parallel, add the amperage (more to this than that, though, like voltages in series I believe are 1/ - gott do a refresher) easy way is by twos: 2 12V batteries in parallel give 6 volts. take two sets of those (4 batteries) and series the parallel sets, and ya get 12V. So if we work with even numbers, say 100a 12V, the above scenario would give 12V and 200A.

Also, make sure you get decent high-current cabling for wiring the batteries up, and from the batteries to the Xantrex. Last thing you want, is a fire from fried wires!

I went by magnumteknologies today only to find out they are no longer there. No answer on the phone listed on the website either. Any other places to get a couple of batteries? Would a deep cycle battery from napa work?

get a slightly used marine d8. not too expensive if you know where to look.

Dang - Sorry about that. Wish I had known to save you the trouble.

Did you try Sun Electronics? www.sunelec.com, looks to be near Downtown Miami...

aww crap now i gotta break out the physics book, i need a lil refresher too lol...

2 12V batteries in parallel will still have 12V but will last twice as long at the same resistance. If you series the batteries, you will double the voltage but will drain the batteries twice as fast.

 

[firewill65]

I understand that running 2 6volt batteries in series will give me 12volts with the same amp hour rating as only one of the 6volts. My question is will my inverter/charger charge the 6volts correctly? Does it even matter? I'm looking for 12volt batteries but have come across some 6 volt that look good. Thanks again!

Yup - I was mistaken. the bottom line: you cannot escape the total power (watts) of the battery stack. For example, 2 12V100a batteries gives a total wattage (W=AxV) of 12x100 x 2 = 2400W
so 2 12V100A batteries in parallel would give 12V 200A = 2400W. 2 12V in series would give 24V x 100A = 2400W. Same 2400W no matter what.

Paralleling gives the ability to add more current/storage, while retaining same voltage. Series gives the ability to have more force (voltage) while not increasing the storage, becasue you are increasing the voltage.

here's a nice writeup I found:

http://www.gizmology.net/batteries.htm

and

http://www.freesunpower.com/battery_diagrams.php

I was confusing resistance with voltage, like how you calculate multiple subs on s subwoofer amp.

So, literally, you could try a single 12V200A or so battery, and see what the runtime is. If needed, you could just add 1 or more later in parallel to extend runtime(s).

I've been reading up and temperature has a big affect on the battery's life....so on that note I will have to store them inside my house in a closet or something to maintain them at their happy temperature which is around 77 degrees. With that said, I think I am going to purchase an AGM battery...apparently they won't spill nor let off toxic fumes into my house, although they cost more. Wow, I never knew how many different kinds of battery's there are out there. I'm sure I'm probably overthinking this but I guess this just comes with owning a tank!
