There isn't one large enough to handle even the smaller tv for an hour. At best you can get about 5 minutes.
For the big tv - CP1350AVRLCD
For the small tv - CP685AVRLCD
If you really need an hour of backup power then you need to modify yourself the units - just open their cases and attach to their original lead-acid battery a big, deep-cycle 100Ah battery.

Ok well usually there is a simple formula to work this all out. We do that by figuring out how many Kilowatt Hours of use we need to be protected for.
In your case, together, you have 675 Watts, + 123 Watts = 798 Watts. Well the best case for you will then be for a One Kilowatt/Hour Inverter. To power them all.
675KW/H & 0.123Kilowatt/Hour, to have enough "headroom" a One Kiowatt Hour unit will suffice.
Divided up, A One Kilowatt unit for the TV.
Another 1/4 kilowatt, or 250 Watt unit, for the other unit.
However there is NO reason why they cannot ALL work from one central unit.
The UP time is simply dependent upon the capacity of the backup batteries. These need to be again worked out by how long you expect to use it.
You would need at least 100 AMP/HOUR of battery, @ 12 V DC, of, power to last the distance.
Hope this helps.

I understand that you require an uninterupted power supply (UPS) for your equipments. Looking at the power requirements of your equipments, I would recommend a UPS of capacity 2KVA for delivering safe power.
You will require a battery of capacity 100AH to deliver the said load for about 2-3 hours. It is always better to take a calculation that is higher in value so that the demands are met easily.
Even a 80 AH battery would be enough but I suggest you can check the cost and decide so that you get the extra time in case of an emergency.
You must check on the make/ models of UPS available in your area and estimate the cost.Please evaluate the installtion which can be done easily.
I hope my advice helps..
