pdath: I'd stick with a plain and simple low cost UPS if that is what you need.  Ultimately you are going to need power for something else.  Having the Internet up during a power outage is no use if you don't have a computer or something else to plug into it.


That was my original thought too. Many people access the Internet on their mobile phones and tablets, and those also keep running during power cuts. It makes sense to power the router (and ONT for fibre) using a more efficient DC-DC power supply if you can get away with it, and it's a lot cheaper than buying and maintaining a real (good quality) UPS.

My unit arrived yesterday, however I'm still waiting on my supplier for the battery (hopefully this afternoon). I won't be using it to run my router (on my UPS), but a remote low-powered computer.

A plain UPS has quite a short run time, they're not that efficient for this type of application. My backup system is:

 

  • A UPS on my PC, might give me 30 minutes runtime, but I'm really thinking our phones will be better for this. Of course each phone has a data connection, and they happen to be on different providers (Spark and VF). We also have a 2deg SIM in the alarm system.
  • The Sentry lite with a 7AH battery. This is significantly cheaper than a 240V UPS, with much longer runtime.
  • A 14AH battery that has 240VAC and 5V USB that can keep my phone charged and run efficient LED lighting
  • I will have A 20-30AH 12V battery which can run the internet connection, charge batteries, etc
I've stopped short of a generator I'm willing to take on that risk, my neighbor has one. Of course I also have food, water, lighting, cooking facilities, etc.
