Make that 5 minutes * 500W/5W or 500 minutes which is indeed a
long time but a lot shorter than the 150 hours you were expecting.
If you want 150 hours, you need to be looking at a backup generator,
so your UPS only needs to last as long as it takes for your generator
to fire up.
That's usually a couple of minutes for professional diesel ones, but
as its home setup it might take you a few minutes to connect it up and
pull the starter cord on a cheap petrol one.
It might then take a few more minutes to drain the tank of the sludge
that used to be fuel last time you used it, and to run to the garage
to get some fresh petrol.
It might take a few more minutes if your spark plugs have been fouled
as you didn't clean it after use, and your air filter has a hundred different types of bugs living it.
So make sure the UPS lasts an hour or 2.
Oh and once you've managed to get it going, and it's making a
tremendous racket, just remember everyone else in the neighbourhood
who is without power will be turning to look in your direction...
I read this and feel first-world superiority for having last year
installed a 14kW Generac system, powered by our municipal natural gas supply. In case of a power outage, it kicks in within about 10 seconds.

When the grid comes back up, it syncs the AC to the grid before pulling
the relay to reconnect. And every other Wednesday, it tests itself for
10 minutes, synchronizing before going off-grid as well as before going
back on-grid.
In case the muni gas is down, my electrician will come over and install
the propane conversion kit. (I don't have a good place to keep propane tanks.)

My house is completly offgriddable because it has a 6 kW PV array, a 6kW diesel
generator and a battery bank worth 15 kWh (which is way more electricity than my house uses up in a day).
Switching power sources caries 0 downtime. The controller is automatable.
I'd argue something like this is the proper way of running an uninterrupted supply of power for home but I also think this is way out of the scope of the discussion. Nobody in their right mind spend 20 kilobucks in a supply system for a computer worth 80 bucks.

It also amuses me how people think that the electricity that powers
their homes is all the energy footprint they have.
I wonder how many lumps of coal a typical Raspberry Pi burns in its manufacture and shipment.
Or how much diesel goes into the organic vegetable basket they buy...

I was attracted by the open source nature of its software, however there
are an awful lot of knobs to twiddle on the slicers.

You will eventually want to come to a deep and meaningful
understanding of pretty much all of them,
but they should have saneIndeed. I take it that the applied tweaks can be stored both in the
defaults to get you going, then it's a matter of learning what to tweak to fix which defect.
My upgrade plans got put on hold - and now they're talking about
the V-Core 4 coming soon.

well it seems to me that rather as with gearheads in music, its more important to play the instruments you have than constantly seek to
acquire better ones.

Yet worse the wayback machine didn't archive the STL (can't say I blame them).

Only if your printer can print plutonium-238.
