Re: Backup DC power standardization with Photovoltiac battery systems?

Simple answer:  No.

Customer routers and CPEs are a mix match of a) voltage - 5v, 9v, 12v, etc
and b) connector - dc barrel, USB, molex, etc.  Fixed wireless and fiber
for certain and I have to assume it's the same story with DSL/cable.

If both PV battery walls and broadband CPE supported Power-Over-Ethernet
as a backup power source, that would work too.  POE supports greater
distances than USB-C.
