[RE-wrenches] string fusing with 3-channel MPPT inverters

[Kirk Herander]

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.
