Help!! I need 8 hours of battery backup!

[Anonymous user]

My company is installing a network system in a very remoter location and we must have 8 hours of backup battery power.

The backup system must be able to support the following:

One router: Power consumption is 160 w max and input current is 4A @ 110VAC
One switch: Power consumption is 148 w max and input current is 1.2A max
Five internet access devices: Power consumption for each is 1.2A 70W

Am I correct to say that the total maximum power requirements for the above system is 658 watts per hour? If so, what type of APC arrangement would met my needs?

Sorry, my user name is " LikeAPro", however, I am very new to this.

I would appreciate any help on this matter.

You can size based on your Watt values as long as they are Max values.

Generally speaking though, if you want 8 hours of backup, the common method would be to have a battery back-up to handle the initial power outage until a generator can kick in to supply extended runtime.

Thanks!

A generator would be great, however this site location is extremely remote and getting a service tech there with a generator could take 6 to 8 hours.

Where I go to plug in the total watts and hours to come up with the sizing requirements?

Hi,

I used the selector here and it provided some 120V matches.

It would be the same to get a service tech to maintain the UPS, wouldn't it? For your loads, SUA1500 should be adequate to carry the load.

With a generator, the power goes out, UPS instantly provides power for up to a minute or so needed for generator to start up and stabilize. Once the generator is running, automatic transfer switch provides power to UPS input.

Get a generator with automatic self-test with visible error status display and you can use an IP-camera aimed at the control panel to check on it remotely.

Although your IT equipment will operate fine on generator power, Smart-UPS is extremely sensitive to frequency deviation, so it might unnecessarily reject your generator.

If that's the case, the online Smart-UPS RT should work better.

If natural gas connection is available, it will provide power as long as gas is available. If not, you'll have to find someone to refuel the tank.

If you go with 8-hours of battery based backup, the recurring expense of changing out 8 hours worth of battery will get quite costly.
