No such happening. No different than having shore power plugged in with converter charging batteries and solar panel putting power into the battery.
The battery will suck up as much power as it needs and both charging devices will provide power as long as the battery is accepting it. When battery is "full" it's voltage will rise and shut charging devices down to float voltage. One may switch to it's float output sooner than the other due to slight differences in how they read the voltage but when the battery is "hungry" both will peacefully coexist and feed the battery.
