Ken / Dolph,
I understand how a transformer will work to step down the voltage, however, I don't understand how a UPS will work to accomplish the
same.
I did some homework and read some info and watched this video: https://www.youtube.com/watch?v=E5RKBWhEUAU but I still don't
understand how a UPS would step down the voltage.
I did find this PW9125-PPDM-6K on eBay:

Rob:
I tend to agree with Ken Burton.
I've installed Eaton Powerware and Liebert online UPS' in data centers. On more than occasion, we had to run the unit off the 240V
line, but the equipment required 110V
These units are basically a power supply, 96 volts of batteries and a pure sine wave inverter. They are designed to keep the gear up
long enough for the generator to start, stabilize and cut over. The inverter is on 100 percent of the time.
I have two 2KVA Lieberts in my home to protect the home theater and the network. They came out of service in NYC's financial
district and you can find them for $300 to $500 used or refurbished (refurbished means they have a new load of "heathen Chinese"
cheapie batteries in place (usually 8- 7A/12 volt SLA batteries).
I think 3kVA should run one AC and about everything else, if you have the shore power to make it a long term proposition.
This is what I was going to do for my coach, until a Xantrex unit appeared in the parts coach (and WORKED).
Of course, in rummaging around old Powerware manuals, i found this:
PW9125-PPDM-6K
Which is a 6 kVA transformer in a box with fans. 100% duty cycle step down transformer.
http://lit.powerware.com/ll_download.asp?file=Schematic%20PPDM%20L6%2030.pdf
Those should be bouncing around at some data center surplus dealers for a couple of hundred bucks.
I guess I'm not a fan of huge transformers in this day of switching power supplies that fairly handily fit in the plug.
That's my .02
My boat guy (a civil engineer who did alternating gigs between Alaska and Hawaii and took a few weeks to sail his home from one to
another) thinks Xantrex may have a box for marine applications that will do what you need as well.
Just say'in...
Dolph
