DSL - green and backup power

[jebatty]

One of those things that took a long time to register in my aging brain. Our DSL/wifi modem has a 12vdc wall wart power supply. This is well suited for a 12vdc solar system; also for a battery backup to keep the modem active for telephone/wifi access in a power outage. In power outages our DSL phone service and wifi access also goes down. Hooking up a 12vdc battery to the modem is an easy and quick fix to keep these active during the outage. The current draw for our modem on 12vdc is 360ma.

Good tip jb.

I'll have to check out the modem and router for that.
Good tip.
Router is 12vdc, but the modem is 10.5vac. Maybe use the inverter I have in the Jeep.
Hmmm.

I have the modem and router on a robust UPS system together with my primary computer. When the power goes out, I shut down the main computer and just run the laptop as needed.

I go to the genny shed and pull the rope.

My phone can last for quite a while without power...

I go to the genny shed and pull the rope.

The outage has to be longer than 4 hrs for me to go that route.

I too have a gen, portable 5500w/240v with a 10 circuit transfer switch on our main panel. A little inconvenient to bring it out and plug in, so an outage needs to be expected to last awhile or I need to be doing something really important to bring it out right away. The computer/media/DSL circuit is on the transfer switch.

I run a battery bank maintained by a 45 watt Harbor freight panel, I have it hooked up to my generator dc output. I can run my heat circ pumps and well pump for 12 plus hours before I need to recharge. I can also charge phones and laptops. I will check out my modem / router that would be great. I have not had to use it yet. In 49 years of my life so far I have never lost power long enough to need backup.

Wow! 49 years no power loss for very long....Must be some kind of record.

Iv never lost power for more ethan a few hours ,at 56 YRs old thats a pretty good record. Got a wood stove for heat in the winter just in case .and a water powered sump pump,what else is there?

We lose it at least once or twice a year, sometimes for days. Looks like I have to go back to plan b, comcast just sent me a new modem with no wall wart power supply, just plugin direct to wall outlet. Looks like I'll have to stick with the UPS and genny. Good news is 53Mbps download. That rocks.
