Hi Kirk,
Yes that is correct. On a three-input inverter, you could have as many as 6 strings of modules, 2 per MPPT input, and you would not need any overcurrent protection on any of the strings. One of the beauties of inverters with multiple MPPT inputs. Along with the fact that the strings can be different lengths, orientations, and even be different modules in each string.

Someone just mentioned to me string fusing, normally required for >2 inputs may not be required since each input has it’s own MPPT circuit. In essence treated like separate single MPPT inverters for fusing’s sake. I don’t believe it, but opinions?
