I recall, they are installing 3*315W in parallel. So - yeah, about tens of amps :)
Words like "and" mean things. MC4s are only rated for 20A, and a 315W panel (24V) is going to put out about 10A, so he wouldn't parallel 3 such panels through one connector, he'd have 3 runs to the controller. But with 24 volt panels, he'd need to be running an MPPT controller to get 12 V out. So why would he parallel the panels in the first place? It would make more sense to run them in series, and have ~100V @ ~ 10A into the controller.

Yes, Amphenol headquarters are in the US. TUV protocol (of their H4 testing) is by Germans.
Uh, what? TUV is the German equivalent of Underwriter's Labs (UL). It's not a protocol, and it's not affiliated with Amphenol in any way, other than that Amphenol may use their services, just as the Swiss Staubli might use UL services for products they want to sell in the US.

As said, no tools are required for disconnecting MC4 and its clones.
A tool most certainly is required for disconnecting them. Since 2008, the NEC requires it, so that's how all the current connector manufacturers make them.
Your responses show a lack of understanding about solar systems.
