Can a BlueSolar MPPT 75/10, 75/15 & 100/15 be used to provide a 24V supply in parallel with a 24V AC/DC Supply?

I'm looking to reduce the load on the AC output due to a 24V control system and I am looking into whether or not a BlueSolar MPPT 75/10, 75/15 & 100/15 could be used to do this, without a battery connnected, just using the 24V load output. Currently 24V is provided by a AC/DC Phoenix Contact power supply. Can I add the 24V load side of the Charge Controller into the 24V DC line? I'm only wanting to reduce load when it is sunny (obviously) and have a dedicated UPS module to provide UPS function between the PSU and the Loads.

@Olliew89 I will hazard a guess it won't work as the PV has to be 5V higher than battery to start it up and without a battery the condition won't be satisfied.
