    As Niel said, no.
    Don't go there if you value the controller.

    Not to mention even though the rated Open Circuit Voltage may add up to 151.23, on cold and edge-of-cloud days you will see that voltage rise 10% or more. My OCV is 100.2 but I have seen it as high as 113v occasionally on those cold bright days.

    No but why don't you split the array into 2 strings.

    yes splitting the array in to 2 strings was my plan...2 mstar 45s each with 3 sharp 235s in with an option to add 1 later thanks for the reply
