Professional grade MC4 crimp tool has numerous issues. Even more issues when I try to use cable which is way too small.

"PV1-F" Cable was used until 2015 and is not UV resistant.
Decent cable should have the “H1Z2Z2-K” marking.
According to the EN 50618 standard, this is weather-, abrasion- and UV-resistant.
But I don't know if the UK uses cheaper cables after UKCA
There are many manufacturers of MC4 connectors. You cannot mix and match the parts, or the brands male to female. I suggest trying to figure out who makes the connectors on your panel, then getting that brand. If you can't figure it out, then you might have to cut off the panel connectors and use whichever brand you find.
There is a bit of a voltage drop at every crimped connection in a wire. By soldering the connection after it is crimped then there is no more voltage drop than the wire itself.
There are special tools made to remove most terminal connectors from the plug. I haven't had to check for MC4 connectors specifically, but I have used them for other applications.
Seems that you are making a big deal out of nothing…Get rid of that magnetic crap and line up connectors by eye!!!! Simple!!!
excellent video. thank you…i have made a mistake and put the wrong connectors on and wrong pins, how can i remove the pins out to start again? hard to find anything on this which seems stupid because surely i am not supposed to throw away the ones i made a mistake on… HELP PLEASE!!
I simply don't use the additional device and align manually as necessary, but then again it is my first time ever using this tool and indeed MC4 connectors.
I saw problems with the mc4 type tool that doesn't have the magnetic side add on also. IN fact , I was very much not impressed with the ratchet jaw tool I purchased. SO, since I use AMP crimps for MANY Years, I use my non ratchet blue amp tool I've had forever. It rolls the crimps perfectly. Also, I wouldn't try to depend on the water proofing at the ends of the mc4. I'd add some water proofing stuff, your choice. . Also, if your system is in snow, EVERYTHING on the panel should be completely insulated. nothing should be in contact with the snow . Corrosion happens even when it is cold. In salt water climates I would go all out. no connections should be exposed at all. Even fiber glassing over things might be an idea. Exposed panels will not last long in marine environments if you don't do some special protective work.
The tool I just got doesn't have the moveable guide, I have to make sure it's in far enough before squeezing. It takes a little more time but I always get a good crimp
Take the holding mechanism off and hold the cable in position.
HOWdy J-I,
you could always utilize the BLUE full sized cable in your MC-4 connector
& then SPLICE your YELLOW Wire onto your BLUE wire down-stream with a BUTT-CONNECTOR
or a Solder Splice & Heat Shrink ?

HOWdy J-I,
Thanks
I beLIEve that your CRIMPING tool is made for a specific BRAND of Connector
to use it for your generic CONNECTORS – you might want to totally remove the Magnetic Rear portion of your TOOL which seems unnecessary ?

Ten amps is not a high amperage. I have a 400A service to my house; and there’s a 50A outlet in the garage for one of my plasma cutters. Yes, that’s at 240V.
Fantastyczny materiał, Dziękuję 🙂
