Plug-in panel. (2 Viewers)

2x100w on roof, wired in parallel.
1x125w stand-alone, "plugged-in" when required.

I've previously connected the stand alone panel to the mppt in parallel with the others.

Is this acceptable practice, I ask, belatedly, or should I put in a second mppt dedicated to this panel ?

Depends on panel voltages...if they aren't the same separate controller
