Help with wiring between panels, inverter, and CB panel

BucklesBuckles Registered Users Posts: 2
My indecision and my add is killing me.
Im installing the 12 panels on a roof.  The roof is 104 feet from the circuit breaker panel.
I cant decide where to put the inverter; close to the panels or close to the circuit breaker panel.
Panels Q-cell 340 watt
Inverter   SolarEdge SE3000A-US-U

Any help is appreciated

    Can you tell us a bit more about the solar panel input requirements for the GT inverter? This model?

    The 240 VAC version says that the nominal solar panel input is 350 VDC, and 500 VDC maximum...

    How did you divide up the 12 panels? I don't see an easy way (6 series x 2 parallel, vs 12 series--Not sure that either meet the input requirements--I did not plow through the GT inverter manual).

    From one point of view, 350 VDC is higher voltage than 240 VAC--So, less voltage drop, less current for the DC power run...

    Safety wise, 240 VAC is a bit "safer" than DC. Do you need a DC shutdown for the array for your building/NEC rules?
