No, it won’t conflict.? Multiple parallel DC supplies will work in harmony, although any one smart supply will be influenced by others – so if you’re on shore power, your solar controller well “think” that your battery is fully charged because of the charge voltage/current from your shore powered converter. Not efficient, but not an existential problem.

This cannot be said for multiple parallel AC supplies….

Will my solar charge controller conflict with the onboard charger when plugged in at a campsite with electricity?
