Less Maintenance

All devices, AC or DC, assume some voltage regardless of the source - off the grid of from an inverter. Your computer operates on 120V, and this is its assumed voltage. This assumed voltage is important. Use a higher voltage and you'll burn it. Use a lower voltage and it won't work. It is of no importance if you connect it to a wall socket on 120V or connect it to 12V UPS via an inverter that transforms the voltage into 120V.

The problem is not getting connected via inverters. It's currently a minor problem to connect 120V light bulbs to 12V batteries. If you have the batteries and the inverter - there you go. But in the Aftertime there will be a major problem with reserve parts. You have to assume your inverter will break, so you need a reserve inverter. If you don't have it, or the last one goes down, your batteries and light bulbs are useless. If you plan to use 12V batteries and 12V light bulbs your dependencies are much lower. Thus, using all equipment with the same assumed voltage allows you to improvise much more than if you depend on inverters and transformers. And this is the main reason I recommend this approach, not because stepping up to 120V can’t be done.
