Battery Backfeeding MPPT Solar Controller

If I have multiple charging setups, should I have any concern with back feeding voltage into the output of a Victron MPPT 100/30 solar charge controller? Or is there some sort of internal protection that I won't have to worry about this?

should be no problem, as example: normally an mppt is connected to a busbar with a battery, charger and other equipment, so when the mppt is not charging there is always DC power on the output
