Do you need 120vac? I have a fair amount of experience with inverters, which basically is a UPS that doesn't come with a battery. I find them to be much better quality than a UPS. I would definitely use an inverter before I'd use a UPS. I realize the UPS have monitoring and remote control features that you might not get with inverters but I'd add something to give me that functionality.
One feature you'll get with the better inverters is the ability to tailor your charge cycle and depth of discharge before the LVD kicks in to your battery bank. If you have the capacity to justify an Outback brand inverter they are great. We use them in the Amazon where we get some wicked lightning and they do really good. Some Engineers that used to be with Trace left and started Outback. If you don't need 120vac and could use just 12 and 24vdc I'd use separate battery banks for both voltages with a good battery charger that charges each 12 volt cell individually even though they're in series. I know of a good charger (I can't think of the brand right now) that does multiple cells. It's basically a bank of chargers in once case. It maintains each battery perfectly according to it's own needs. Though that charger is not adjustable, it's strictly for normal lead acid deep cycle batteries.
