An important note about connectors that isn't pointed out in this video, there's only 1 true MC4 connector, now made by Stäubli. All other "MC4" connectors are "compatible", but even that is an exaggeration. You should only use connectors (or cables) from the same manufacturer in your setup because every connector, essentially the mating pins, has different tolerances so you will create resistance with your wires and will also create a potential fire hazard. So for safety and better efficiency, don't mix connectors from different manufacturers. It's also a good idea to use a crimping tool designed for the manufacturer’s connectors.

Can you use closed-barrel pins?
Your accent makes it very hard to follow.
