Why not run your system at 54 volts? If the radio freaks out above 54, just
set it at 54 and you should be fine. Battery strings don’t exceed the float
voltage of the rectifier. If you are worried about it float at 53.75 volts.

Having a hard time figuring out the exact part/price for something like this.
Which Meanwell part would take 48v and make it 50v or 54v 5A?

That's weird to me. Any telecom equipment made for 48v I would have assumed
they intended it to be used with a rectifier, and consequently I would assume
it'd be ok up to at least 56v continuous; and maybe more like 60-70v for a
short duration. But yeah, DC-DC converter is the fix.

Meanwell has a good selection.

Apparently the UBNT EP-S16 freaks out if it goes above 54v.
Is there any way to assure it doesn’t float/charge above 54v, or maybe even
just 50v?

contact talley or tessco for a price, don't trust what you see on google,
it's like 50% less

all 48v systems for battery power will float at 54v, it's also adjustable

Ok, cool.
So can the 7bc2 be adjusted slightly to output 50v instead of just 48v?
There will be some loss going 100’ or so, right?

12-54v is inefficient, if you want 200ah of battery use 4x50ah
batteries for a 48v string
ICT24048-7BC2 360W 54v AC-DC + LVD + Charger
ICT-TMP - Temp sensor for charge compensation if batt's outside
ICT-WMB - Wall mount bracket
SITE Monitor - Voltage monitoring
Or
Alternativly;
48v din mount PSU
48v 'dc ups' to charge batt's and provide LVD
OR
48v din 'dc ups' with integrated psu + lvd + charger (i.e. DIN-UPS 48-5
cheaper options available)

I’m trying to put a “box” system together for our house POP sites and
need help with the DIN stuff and UPS.
Can you guys give me an idea or example of the following?
I want to take standard AC 15A in from a breaker outside the box.
And using maybe one or two 12v 105AH AGM batteries, supply 50v 6A up
the side of the house.
I have never ordered DIN parts like this, guess I don’t have to use
DIN, but would be nice.
Having a problem finding a DC to DC converter that takes 12v and
upconverts to 50v 5-6A.
Is this the cost effective method? Something like this:
Monitoring Sitemonitor Base Unit II SMON Base II
1.00 $100.00
$100.00
UPS Monitor Sitemonitor Int MorningStar MeterBus SMON
MorningStar 1.00 $60.00 $60.00
UPS Charge MorningStar Sunsaver Dual
1.00 $165.00
$165.00
Battery AGM Deep Cycle 105AH NPP FT12-105AH
2.00 $225.00 $450.00
DIN Parts like DC fuse/breakers and trunk stuff
1.00 $100.00
$100.00
DC 12v to 50v 5A
1.00
$150.00 $150.00
