Need help determining the operating costs for APC Back-UPS Pro 1000, 1300 and 1500

[Anonymous user]

Here's the scenario I would like someone to test:

Start with a fully-charged UPS with no load.  Use a Kill-A-Watt type device

to measure the accumulated number of kwh used during a month (or week)

of operation when no power outages occur.

After all, many of us go many months without any power outage.

So the results of this test would represent the typical operating

cost of a UPS.  I'd like to see the results for the Back-UPS Pro 1000, 1300 and 1500.

I'm guessing some of you have already done this test.  What were your results?

I don't know if this would help? It is a UPS efficiency calculator and basically if you drag the load percentage to zero, it is supposed to give you what the UPS power draw is. Might be worth a look.

Angela,

  Yes, http://www.apc.com/tool/?tt=5 was relevant and somewhat helpful--

though rather finicky to use.

  For one thing, the results indicate that there's not much difference

in the operating costs of the Back-UPS Pro 1000, 1300 and 1500:

The BR1500G only costs about 15% more to operate than the BR1000G.

I'm not 100% sure that I believe that, but maybe it's true.

  The operating cost figures were close to the very brief tests I

performed on my BR1000G:  About 5 kwh per month with no load,

starting with a fully charged UPS...in other words, just to keep the

UPS fully charged.  At California's max. (and typical incremental) rate

of 32 cents per kwh, that's $1.60/month or $19.20/year.

  I'd still like to hear from anyone who has done this test for a week

or longer.

It costs a lot less to run the BR1500G for 10 years than it does to recover the data from a crashed hard drive that was unprotected.
