I really don’t view it as an optional feature. The way the Traco BCM works is that it controls the voltage of the power supply so rather than the nominal voltage like 24 or 48 volts, it is set to the proper voltage to charge the battery, like 28 or 56 volts. It comes with a little 2 wire jumper cable that goes between the power supply and BCM, and also a temperature sensor that you attach to the batteries. If you’re not going to use it that way, I think maybe you should find a different product.
I’m guessing you are using the manual voltage adjust on the Mean Well power supply with a voltmeter to set the voltage to the float voltage you want for the batteries and also the voltage that the loads will see. If the batteries are outside and subject to varying temperature, this is going to undercharge or overcharge your batteries depending on time of year, solar heating, etc. The BCM will allow a fairly sizable battery charging current, so overcharging will probably reduce battery life quite a bit. Undercharging will hurt your runtime. Overall, it’s non optimum. You’re using the Mean Well as a dumb charger, and the BCM as an expensive low voltage disconnect. Not sure why you don’t want to use the TSP series power supply. Somebody suggested the 48V version of the Mean Well USP that appears to be an exclusive OEM by that fiber equipment company, that may be what you want.

BCM signals TSP to adjust voltage. I assume the AC alarm comes through that link cable too.
