Keep in mind, I ditched my Jaboni 30A controller for a Victron 150/85 for the example above.

Sorry, but you are not looking at the specs of the Jaboni panel. Your panels are not the same voltage. They are not doing it wrong, at all.
According to the Jaboni specs, the 300w panel max voltage is listed as 32.26v and max current as 9.3 amps (300.18 watts). The math is clear that two of those panels would be under 20 amps and the provided 30 amp controller has room to spare.
This is in agreement with prior posts on this forum and information from Matt at Future Sales, all of which have suggested that adding one more panel is easily handled by the 30a controller, but adding a 3rd panel may be pushing it.
