For a large fixed system putting hundreds of volts and tens of amps through them, sure - stick to one brand.
I recall, they are installing 3*315W in parallel. So - yeah, about tens of amps :)
Brand and monopoly aside, MC4 clones from questionable sources like Ebay are very often hit and miss. From a biggie like CS it should be TAD better.
In the worst case, you can get a crimper and replace T4 with MC4 if any issues arise. Hide them under the panels, they will last longer. If Mex were reading this, he would've probably told to smear it all with dielectric grease or Lanolin. In humid environment I would do this.
Yes, Amphenol headquarters are in the US. TUV protocol (of their H4 testing) is by Germans.
As said, no tools are required for disconnecting MC4 and its clones. Not "very" easy after it's been sitting for more than year, collecting dust and salt deposits, but doable - with bare fingers. I would not replace T4 with a connection directly to panel unless this could be done without soldering. It's better to keep it detach-able. I would not replace T4 with Anderson, unless frequent disconnecting is in plans, like using them in a portable setup. Definitely would not replace T4 with SAE.
