Home Infrastructure
My home networking gear is sitting on a UPS right now. My power is reliable, but every now and then it goes down for an hour or so. It's rare, but it happens. To solve this, I took an old UPS and added a couple bigger batteries, which sit on the shelf next to it. This provides 18 Ah at 24 VDC, which is 2-3 times the capacity of the original batteries. My total load is a hundred watts or so.
This has worked well. I would, however, like to make some changes. I have some smaller network devices, a switch and Raspberry Pi in particular, which could run just off of 12 VDC. I have toyed with the idea of powering these directly from a battery floated across a power supply, or with some kind of DC UPS or switching arrangement. It would also allow the possibility of adding #solar power into the mix, adding it in parallel.
This is a low priority, as things are working now. But something to think about for the future.
