Beginner, Need Help With Wiring

[Siamac]

Hi everyone. I'm new. This forum is a great resource. Can you please help me with the wiring? Just want to make sure I'm doing it right.

Equipment :
IP6048 inverter, 2 MPPT, 125-550V, max 6500W
2 strings of panels in series
(no battery for now, maybe down the line)

This is my plan step by step.

1. Wire 5-10 panels in series (49 VOC) , connect each one together
2. Connect PV wire, about 70 feet (probably less) from roof to inverter in garage with 10 AWG PV wire. Questions: do I need disconnect at roof? Do I need disconnect in garage if inverter has PV off switch? Do I need conduit from end of the panels to the inverter in garage? How do I ground it? Run Grounding wire from panels to the subpanel? (Subpanel is grounded to main panel)
3. Wire inverter to subpanel. Questions: what gauge wire from inverter to subpanel? Is 4 AWG THHN good? 50A breaker? Do I need conduit from inverter to subpanel?

Any advice is appreciated

I think not

Do I need conduit from end of the panels to the inverter in garage?

You can choose solar cable entry gland if your garage roof is flat. Or PV combiner box, can do the work better as it makes the wiring clean and safe.

It depends…

Will the local government look over the system and make sure it is up to code?

I believe code requires a PV break switch - I don’t know if that is outside or if on the inverter inside the garage will be sufficient. That PV breaker is for the Fire Department- so my guess is it will need to be outside and labeled.
