Misleading information from a supposed reputable? company

This video demonstrates how misleading information can influence people's opinions and ultimately decisions on what is the best controller. There is some information which is valid, the MPPT controller will have an advantage over PWM with a 24V nominal panel, that's because the PWM is not designed to use such a panel, it would need a 12V nominal panel so as not to be so grossly over voltaged, if a 12V nominal panel were used with the PWM, the difference in results would be less dramatic. The comparison should use compatible panels as described above, but also introduce temperature, the actual deciding factor, as the temperature drops the voltage increases which is where MPPT has its advantages, in a tropical location where temperatures are consistently high ~30°C or above, not so much. Judging from the comments in general many were wowed by the apples to oranges comparison, probably due to ignorance, they merely believe what they saw assuming it was gospel. Ignorance is not stupidity, but believing everything seen on YouTube is factual, is getting pretty close.

I suspect everyone here has had people just go blank when you are explaining the difference.
This is why engineers are no fun at parties.
