Just curious: do you continue to get TV and internet when the
regional
power is down for days/weeks?

I have determined that my cable system (Spectrum, formerly Time
Warner) stays up for five hours after an outage. That's a
disappointingly short time.




Do you have any idea how much power it takes to run a CATV
distribution system? Those pole mounted power transformers are a
60V,
30A modified square wave from a Constant Voltage Transformer.

That is 1800 VA, continuous, and typically powers about a half
mile
of CATV system. How much do you want to be added to your bill, to
extend
that three hour design?


Go to your local phone company's central office. Take a look at their
backup power and then tell me how I get dial tone for $11/month and
it's got enough batteries to last until doomsday, and enough generator
& fuel to last till the coming of the messiah.

========================

I built a test load for a 48V 1000A central office battery charger, to
replace an old wood-framed one that had burned up. I didn't tie down
all the 4/0 welding cables for the initial test and when we switched
it on the suddenly magnetized cables slamming into the metal frame
sounded like lightning had hit the building.


I'll bet the janitor had to sweep up a whole lot of buttonholes that
evening.
