I have a small off grid solar setup. Evergreen 47W panel, through a 4.5A SunGuard charge controller connected to a 12V deep cell marine battery.
I currently power one network hub in my house by going through a 75W inverter, then to the power brick to 7.5V DC into the device. I know this is not efficient.
What I would like to do is to power the 4 (or as many as I can) network devices (hub, cable modem, wifi router, and switch) with DC-DC step down converters. While looking into that route, I noticed that 3 of the devices are actually 12V DC inputs. What I'm wondering is can I power those devices directly from the battery (through a DC fuse of course) when I know my battery voltage varies from about 10V to 14.1V without harming the devices or hampering their performance?
Anyone have experience with this or know what the tolerance on Netgear home networking components are?
Thanks,
Jon
