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
I'm installing a 3-input SMA 7.7kw inverter. 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?
Thanks
I'll rephrase this and possibly someone has a suggestion. In the Bahamas
(they use CEC 2015), they are currently not allowing any load side taps in
gentran switches. They suggest including a large, expensive load center
with backfed breakers to combine the utility and pv ac output before
connecting
