....mind you I haven't done it. It just seems like it would work.
What Bill said about wire gauge is true too.

That does sound convenient.

BCMU does not automatically make that work. We've been running a 48v
system and adding a 48-24 converter. You can do it the other way
around too.
Personally, If I was going to do something other than 48v on the
battery system, it would be 12v. The reason being that if the battery
system was 12v then my portable standby generator would be any car with
jumper cables. In theory it sounds convenient.

More dummy questions… If I have mostly 24v battery arrays now, and
want to be cheap and not buy more batteries, but need 48 volt to the
equipment up the tower, does the BCMU make that work somehow? Or do I
need to have the battery array become a 48v? You mention a “12v
battery string” so am not sure.
AND, if I also need to drive 24v up the tower (different RAD center,
dif. Equipment, do I need another power supply, or can I somehow pully
both 48v and 24v for output?

First step is to decide if you are using the BCM or BCMU.
BCM will need to control output voltage of a Traco power supply. BCMU
just needs power in. Main factor with BCMU is it takes a 12V battery
string and has limited charging current, so if you have a lot of Ah of
batteries, it might take days to charge back up. But the BCMU is more
flexible … U=universal.
In any case, be sure to disconnect the AC and let it run the battery
down a bit, then reconnect the AC. I had a BCM installation that
would pop the circuit breaker after about a minute because of the
extra battery charging current. I was unaware of this problem until
the first big power outage, because I failed to test it.

Hey guys I am completely new to Traco, so am feeling my way through.
It seems like power supply itself is not relevant. But the BCM is.
Someone suggested using a TSP-BCM24 or TSP-BCM48 instead if I already
have 2 or 4 batteries in place,
What say you?

Not sure about the HRP. I've had SDR's running for years now.

PSUI is who we order Traco stuff from. Do you need 360W? The Mean
Well SDR-240-48 is an alternative. That's what I'm using with the
Traco BCMU360's. If you read the fine print, it's worthless to put
360W behind the BCMU. They're rated 240W continuous and 360W for 3.5
minutes. And the SDR-240 is ~$70 vs ~$270 for the TSP360.
If you really need it, there's the SDR-480-48, which is only 1/2 the
price of a TSP360.
