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?

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.

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?

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.
