Will a PSPV Handle 602 amps
I Have 28 Panels 155 watt 17V-9.1A-9.6SCA-21.5OCA at 12V. I was thinking on tying 4 in each string. With a PSPV in two 48V legs. One with 4 sting to a mx60 and 3 string to the other MX60. Will one PSPV and 7-15amp breakers work for this? Can a PSPV handle 602OCA? I was told that I wouldn't be able to.
Why not go out on a limb! That is where the fruit is at.
I don't think you will have 602 Amps to contend with.
If you put 4 modules in a series string, the current in that string will be no more than a single panel will produce. So, if one module can make 9.1 Amps, that is all that will flow through that one string of 4 PV modules.
9.1 Amps (let's just say 10 Amps) times 7 strings is only 70 Amps total.
One 15 Amp breaker for each string would be fine.
If you are using a 12 Volt battery system voltage, then 4 strings for one MX60 and 3 strings for the other MX60 should work good also.

We had ETL test the PSPV with twelve of the 15 amp breakers in it. (180 amps). They ran the 180 amps through the combiner busbars as well as through the terminal bus bars. It looked like we could have gone for a bit higher current after all was said and done. Oh well, 180 amps will have to do for now.
