Also I will set up a 65" 4k tv, ps4, Onkyo surround sound, and other small appliances.

Please describe, in detail, what you mean by "power inverter ".

I want to see if I can take 4 dc batteries with 400amh each to hook up to a power inverter to use for my pc needs/small appliances without going through the trouble of running a dedicated circuit.

Hi

Get a qood quality ups or talk to dealer who speciases in ups
How long do You need to run system for between charges ?

Idealy you want a inverter which produces full sine wave AC
To avoide the psu going up in smoke
.

Is there a ups that can handle 2000w? and I would say 8 hours but since I will be working on this pc maybe 12 hours max and 12 hours resting. Yea I read into that because of the square like wave forms are not close to the sine wave.

Running that PC for "8 hours* will require a few thousand dollars worth of UPS, and weigh several hundred pounds.

For instance, going through the calculator at APC

600 watts for 8 minutes is a $210 UPS, and weighs 30 lbs.

So what I was thinking of is maybe using 4 6v 400amh deep cycle batteries to supply power to the inverter for my needs.

What calculations have you done to show that this would be possible?
Which specific batteries are you talking about?

 

[USAFRet]

And why are you wanting to run this on batteries?

So to bother you with this. I wasn't paying attention the other equation I did and thought I didn't have enough watts coming from the outlet.

Using an inverter or whatever does not fix your wall outlet output.
It is not a magic bullet. In fact, it is far worse, due to simple inefficiencies in the system.

Lets start looking at this logically. I have a APC SmartUPS 1500 rack mounted. It has 8 12v 5aH (500maH) batteries in series in it. With just one server, without the 3 980Tiz but just integrated video, that will give me maybe 30-40 minutes of run time. Each of these UPSes weigh about 63.1 pounds. You can attach a batter pack to it which will add an additional 40-60 minutes to that single server but also weighs an additional 120 pounds.

So for maybe 1.5-2 hours on a single dual CPU server you have 1.5-2 hours of run time on a UPS.

Add in the 3 980Tis and that would probably drop to 15-20 minutes.

It is not possible unless you have a ton of space for the batteries because 4 6v 4aH batteries will not do it.

Dual Xeons, and 64gb ram, for a "desktop" PC?

Okay and thank you for your reply.

It's a dual xeon workstation.

I wasn't trying to fix the outlet output but do an off grid rig.

 

[Onus]

Wait a minute please...
OP is talking about 4 of the great big 400AH batteries used in off-grid systems. Two parallel pairs in series will amount to 800AH of +12V power for the inverter.
Twelve hundred watts at 120V is 10A; which becomes 100A at only 12V. A straight conversion suggests an eight hour run time, BUT there's this "thing" called a Peukert Curve to consider, which essentially says the faster you drain a battery, the less of its rated capacity you'll get out of it. Just my guess, but I'd think a discharge rate like that might last six hours, max.

Edit: That was also before losses in conversion (no inverter is 100% efficient). If you double your battery capacity, you would probably hit your runtime goals. Keeping those batteries charged though, could be problematic unless you have a lot of solar capacity and/or live in a high wind zone area and use one or more large enough wind turbines.

"off-grid"
What is the rest of the house doing?

Sorry man when I thought of this I was over thinking the situation.

It's a dual xeon workstation.

Then depending on work being performed, you probably should be using quadros instead of gtx cards.

Yea this is going to be my almost all-purpose build type workstation. Yea I thought about it in and out and the specialize drivers I probably wouldn't need as much unless doing heavy CAD type work plus if I did I could always spoof the gtx to read as a quadro. I just didn't see the price/performance was there when comparing the gtx 980 ti or titans.

that site suggest a UPS (30 pounds) and *10* battery packs at 70 pounds a piece to get you to 8 hours. at a cost of $5600+ to deliver. very heavy.

Then how the file-socket do you recharge them?

if you're going off grid, you'll be better off with one of those $100 one-child-one-computer laptops that charge up like a cell phone, or at most a tablet or something like a surface or 8-hour untrabook, which you can charge off your existing solar cell or wind turbine that runs the rest of your survival bunker.
