Uninteruptable power supply - ups

[plzhelp]

i just realized i need a ups
id like to get one that could run for 24 hours, but i don't know if they make them with batteries that large
the websites of toshiba and the other companys are not very helpful
i need to run my 600w lamp, small air pump, small water pump, and small exhaust fan for 24 hours
probably adds up to less than 700w total
so the stats on my ups need to be at least:
wattage: 700w
battery: 17kwh or 60 mega joules
does anyone know anything about ups?

It would need to be a true sine wave UPS.

You need a good size backup power inverter (true sine wave) and a matching deep cycle battery back for storage I prefer Rolls Surette 2v cells. Battery bank needs to be in a ventilated area as it makes hydrogen gas when charging.

So your looking at a very large investment.
