It’s a piece of engineering art. Besides, Morningstar is known for their great tech support, so should anything happen they will promptly respond and take measures. A1Solar has also been a great partner so far

A very solid device packed with features for tracking performance. I had a few display freezes in the beginning, but after a firmware update I’m 100% satisfied with the device

If I exceed Nominal Max. Operating Power, it won’t harm the controller, right?

Yes, this will not harm the controller given Open Circuit Voltage is not exceeded.
Is it a good option for a boat?
