Other than ONTs\modems that have support for battery integrations, there re= ally isn't anything that's appropriate for keeping a sub 50 watt load onlin= e for a long time.

What we need is something that d= elivers 1/10 that much power for 10 times that long.=20 Yes, I realize a big part of the problem is the inefficiency of DC/AC conve= rsion especially at low power levels. And there have occasionally been DC b= attery backups for network equipment, usually for a specific model of CPE. = But we are often faced with a radio that wants 24-30 or 48-56 VDC, and a Wi= Fi router that wants 5 or 12 VDC.=20 If this was for our own use, I could build something with some DIN rail ele= ctronics and a battery, but it wouldn=E2=80=99t be UL approved or appropria= te for a customer to use in their home.=20 People these days get alerted on their phone because their doorbell camera = is offline, and they call their ISP rather than check for power outages.
