new device x-ray machine with max 2.5 seconds 100A @240v

economical ways to supply this?

the generator is rated 10kw max, 9kw cont.

budget? low...

I've not added much detail. I am looking for storage ideas that are economical.

I am unsure of how many xrays would be done each day, but let's think on maybe 1-2 dozen...
