My Morningstar controller has been sharing duty with the battery charger for 
years with no ill effects.

Good point!  Not all voltage controllers are the same.

Keep in mind that the controller will simply see a higher voltage on the 
battery and will stop charging. No ill effects.
My morningstar controller is permanently connected to the battery  (actually to 
both, but it is a dual controller). Any other source of charge has simply to 
compete. But all of them depend on the voltage, so they can easily work 
together.

No assumption needed.  When we have several days in a row that are rainy and 
overcast (like lately) my 300 watts of solar panels can’t keep up with our 
(livaboard) needs and I have to turn on the battery charger.  There are no ill 
effects since the controllers only allow electrical power flow in one direction.

My natural assumption is no.  If you turn on the charger, the solar
controller is probably just going to turn off or reduce output.  The only
thing to be concerned about is connecting or disconnecting the battery
while the solar panels are connected.  The load on/load off surge is
probably not good for the controller.   Many of them have a connection
sequence stated in the owners manual.  Usually its battery on first then
solar on.  Reverse the sequence to disconnect the controller.

Stus-List Solar power controllers
