mppt vs pwm

If all four panels were in connected in parallel, it would give me 544w @ 24VDC (just under 23A). Running this one feed to the inputs of three 20A controllers should balance out between the controllers. Am I missing something in this type of setup?

The wiring itself would be easy enough;

4 panel pos and 4 panel neg to a pair of 4-into-1 'Y's... Two wires to a pair of 3-into-1 'Y's, near controllers... 1 pos and 1 neg to each controller.

Not really sure how well it would balance out?

I do like the redundancy, though.
