For an ILEC, the statutory requirement used to be 8 hours minimum battery
life. I think that is a reasonable amount if you have a generator or have a
portable that could be connected within the 8 hour limit.

My worry about the 30KW of batteries is a "what if"... It's basically
a monster electrical bomb... I fused them, but if something happens to
one of them in the rack, it isn't going to be pretty... Water is my
worry...

It’s that ‘almost’ that drives me nuts. With over 100 sites and multiple
generators the odds of all of them starting all of the time are low. Yes
we do self tests (and sometimes even notice when they fail) but even then
they sometimes still manage to let us down.

My generator "almost always" will start and run in 2 minutes. I just
realized that I did not do what I used to do with all the generators. I
would relocate the battery into the temp controlled building and put an
aux trickle charger on them. We need to do that with my latest central
office. I also had telemetry on them so we could remotely check on them
to see if they were exercising each week.

Heh…. 2 minutes while the genset starts is a fantasy. Minimum is 4
hours of battery so when the power goes out and the generator fails to
start that you have time to go to the shop, get a portable generator,
drive to the site and beat the standby generator into submission or hook
up the portable. 24 hours of battery if you like to sleep.

20kw genset with transfer switch is 5k. don't know if this is a better
solution. I would venture to state that it would not be. Drop in a
genset and a small battery just to keep things up for the 2 minutes
while the genset starts.

How much vs Generator?
I have always been a fan of both.

I would never want to be without a generator, irrespective of the
size of my battery. A car crash on the right pole can have you out
of commercial power for days, I know of one road it was out for a
full month. Freight train caught a transmission line and about 20
100’ poles all snapped off like dominos.
