The term that got us cheap power was "unmetered CATV power supply".
They allow connection of a fixed capacity power supply unit with no
meter, just a small disconnect and drop a 120V 10AWG service and bill
us based on half of the power supply's nameplate capacity.

I read about one of those that is already pre-packaged in a lead
coffin. It does have a bad history with 3 kills and about 1/2 dozen
sickened... You have to provide the deuce and 1/2 with the shielded
drivers compartment.

I got some old Russian thermo electric generators that are self heating. They
are pretty good for things like this. You will have to pick them up though,

You can use 9dot and do your power control, dc in on solar panels 48 volt
system..Just another option, lots of reporting and metering there..

Electric "can" be more cost effective unless you have to run wires a
half kilometer or more. Our first remote POP was not quite a 1/4 mile
from the nearest electric source, so we had to trench that distance, run
conduit, and run relatively large gauge wires that distance. At that
time, the
Some places have what is called a “street light tariff” that is about as low as
you can get.

I can save you the suspense. If you have access to electric that’ll be cheaper
than solar. The problem is the need to run 24/7. You have to design around
the December-January months. I’m in NY State, and at our latitude we only get
a few hours of average production per day during those
OMG get meters. The panels and batteries will cost more up front and they
won't last as long. Solar sucks here in Ohio, it's only going to be worse
where you're at.

For critical telecom I always used 20x the load power for panels and 2 weeks of
battery autonomy for bad weather.
If you can access the site in bad weather to clear off snow or give it an aux
charge you can go less.
I would still recommend 10 x on the panel size and at least 4 days of battery.
Steve,
Ah ratings are only good for one specific amp discharge. More current = lower
Ah. Less current = higher Ah. The full specs of a batter should give you a
table or curves showing the different Ah capacity for different draws.

Four 150ah batteries would be a lot more coin than 12v to 48v if you can
afford the run time loss.

we have a dozen or so, but are looking at pole mount micropops (our own
poles). We are losing a grain elevator site because they decommissioned the
elevator and theres no real options for the customers in some of the areas.
Im just trying to get to something we can get solar power with enough
How many of the batteries do you have? Do you need any voltages other than the
48 volts? If you have 4 batteries and only need 48 volts then wire them in
series and not have to deal with the converter.
Thank you,

*You’re around C/30 which should be on the high end of capacity.
Lower load usually means a little extra capacity out of the battery. I
realized that sentence might have been ambiguous.

You can do the whole thing in Watts.
12V * 150ah = 1800 Watt-hours
1800Wh / 50W = 36 hours
If they’re telling me 95% efficiency, I’d assume 50W out needs 53W in (50 /
0.95).
There’s usually an efficiency curve for the device based on load and
temperature so it wouldn’t be 95% in all
15 matches
