No, they won't affect the mppt function, but the magnets could likely denature die to heat so may not be the best move.

Also the heat sink is aluminium. Just interested to know what glue (if that is what you were going to use to attach to the mppt) would also handle the heat? Or did you have another method you were considering?

No glue. The MPPT has some lateral cuts where you can fix the magnets.

Here's below how I've attached some neodymium magnets to my Cerbo and then fixed it on the face of the Multi RS.

And each magnet has a adherence force of about 1.5Kg, so a total of 6Kg for a Cerbo. Almost the same as fixing it with screws....

In a mobile install vibrations will allow the magnets slide down the mppt?

Well, depends on the vibrations...

I suppose on an RV, on some Australia's corrugated roads, after several hours, maybe... :-))

Mine is a stationary install and never moved a millimeter.

Thanks Alexandria, i mounted the controller to a piece of sheet metal and was going to put magnets behind that. but if you think there is any downside i will go another route
