On a motorhome with each string with varying shading throughout the day from air conditioners and such on the roof. Each string is five 100w panels. Currently Midnight Solar Classic 150.
Any advantage to changing to 3 Victron controllers?

I would think you may get a little bit more, like 5% maybe 10% max but it may not be worth the change.
shading is always a issue when on one controller in some way but on 3 its much easier to control and to maximize the panels
But the only way to know for sure is to give it a go.
I have never done it and tested it so my answer is a gut feeling reply.
The theory of MPPT says it should make no difference.
He / she has 3 strings, as soon as one string is partly shaded it has different properties than the other two strings, MPPT is good but not magic.
But I agree, the real gains might not be very high, so I'd only try it when there is a shortage of power, and other solutions (less shading, different panels) aren't possible.
