This charger charges my 24v agm battery up to 29.4v. is it dangerous?

Hi, it is not dangerous, it is for the proper charging of the battery

I'm plannng to have 3x150w solar panels on the roof of a van. Which Steca will I need for a safe 12v system?

No this controller is not suitable, depending on the technical characteristics of the solar panel you'll use, you'll need a 40 or 45 A solar charge controller. From Steca you may look for Solarix 4040 or Tarom 4545, the second will certainly be suitable for your system

What is the upper limit for voltage in charging 24v AGM battery?

Hello, the maximum open circuit voltage of module is 47Volt at minimum operating temperature.
