What Isolater / breaker ?

I am using 12 x 320Wp solar panels, devided into 2 strings, each 3 panels in serie 2 in paralel.

All connected to a Victron Mppt controller 150V/85Amp. The electrical code states that all incoming wire to the Mppt controller have to be secured. What type of breaker is best and what characteristics do I use.

Regards,

T.

Do you mean two arrays of 6 panels each?

And one array with 3 panels in series (in a string) and 2 strings in parallel?



Are those two PV arrays facing into different directions?
