    OK, there have been quite a few comments criticizing me for showing a way to crimp MC4 connectors with needle nose pliers. So I'm going to sticky a response to give you some context.
    First, it ABSOLUTELY is possible to create a good, solid mechanical and electrical connection with needle nose pliers. It is much harder to do and less reliable, but it CAN be done. This is especially true if you crimp it with needle nose and then solder it. Either way, I demonstrated this method because there are thousands of people out there that are just installing a single solar panel for a light in their shed or a small pump for a garden water feature. There is no need to invest $30 in an MC4 crimper that you will only use one time for one single panel.
    Second, the method with needle nose pliers should ONLY be used for very small systems. Obviously, if you are installing a larger solar panel system or you are a professional installer you SHOULD be investing in the right tool for the job to reliably make a good connection. I would have thought that would go without saying, but I guess it needs to be spelled out.
    Third, all of my solar videos are for OFF GRID, LOW VOLTAGE systems. If you are looking for best practices and methods for installing large, grid-tied systems, please look elsewhere. As such, it is EXTREMELY rare for a fire to start on a low voltage, off grid solar panel system. I have installed numerous systems for customers, advised thousands more customers over the years, and talked to off gridders all over the world and I have never heard of this happening. Can it happen? Of course. But it is much, much harder for a fire to occur than in high voltage, high current systems like you would see in a grid tied system. In fact, arc fault interruptors are only required on systems exceeding 80V+ DC.
    If you disagree with any of this, fine. That is your opinion. Feel free to start your own RUclips channel and educate everyone better than what I am doing. But I'm tired of listening and responding to the hand-wringing and your comments will just be deleted from now on.

    I got hung up and was trying to make sure which connector is positive and which one is negative... Well, the correct answer is both... It depends on which working end of the cable you are referring too...
    More important is making sure that you are putting in the proper metal innards into the proper plastic outards as they can fit inside the wrong connector, ...but won't connect... I am going to have to redo everything that I did this last weekend as soon as I get more MC4 connectors as once they go together they can't be reused (as far as I can) once the metal snaps inside the plastic they simply will not come back out... I am learning and if I can do it wrong, I will do it wrong the first time... 🤔😀

However, I have also seen the opposite concept, where it is considered that the male connector is the one inside which the closed-end metal pushes into the metal pipe of the other part.

    Great video. The only one that explains that the male and female metal inserts go into the female and male plastic respectively. I had to replace the connectors on an REC Solar panel whose junction box wires were so large in diameter that the MC 4 grommet did not slide over them. These wires had an outer layer of insulation over a thicker inner layer. After trimming back the insulation to 1-inch like you recommended, I had to trim off another 1/2-inch of the outer layer to accommodate the grommets. Thanks again.

    • @LDSreliance

      Yes, there are lots of little things like that in videos that you forget or overlook and wish you could go back and add in. Obviously the pliers method is inferior and there is a very slight chance you could have a problem. BUT it does work and I have done it before and it can be a solid mechanical connection. And I do believe that for tiny hobby or point of use remote systems where someone might be tempted to use pliers, the risk of a fire or even wire failure is extremely small due to the low current of such systems.

    If you are making connector cables, pay attention to which cable you are going to connect to which lead of the panel. You will likely connect black band to red band and that means putting the black band MC4 on the red wire. Depends which end of the wire you're talking about but don't just match colors all the way through. Pay attention to plus minus off the panel and plus minus with your connectors. I think the special tool is also for taking them apart to spring the clips.

    • @dragon7689
      @dragon7689 Год назад +1

      It depends which side you are making. Most panels have male on the positive lead and female on the negative lead. So if you are making a cable to extend those wires, then female on positive and male on negative to plug in to your current connection but then male positive at the other end. This also helps when putting panels in a series string.
      Technically you could make all of them off the panel males and all connections female but then you must pay attention to colors and how you are wiring it up. The opposite connectors reduce the possibility of crossing the connections later and allow for easy installation of series strings.

      You can but it is designed to not need it. I demonstrated with both needle nose (sub-optimal) and proper MC4 crimpers. If you are using just doing a one-off project you can get by with needle nose and for good measure maybe some solder. But if you are doing more than a few of these I would invest in the proper crimpers.

    Hello i have a question. My solar panels are cheap ones from Harbor freight they was a gift 4 sets of them for a total of 400 watts. Now they do not come with mc4 connectors. But from my charge controller to the panels there is no connectors just bare wire. I was thinking of using mc4 Connectors. I have crimping tools and what not. I just hope i understand this coming from the charge controller the Positive Plus + side using the Negative Minus - MC4 connector, And the Negative Minus wire coming from the charge controller goes to the Positive Plus + MC4 Connector? Then the Solar panels the the Positive Plus + wire goes to the Positive Plus MC4 connector and the Negative minus - wire from the solar panels goes to the negative minus - MC4 connector is this correct?

    • @LDSreliance
      @LDSreliance  7 лет назад +1

      It is not possible to hook it up wrong. The MC4 connectors themselves do not have polarity. I think they just put + and - on them because those are the ones that are usually installed on the leads from the solar panels respectively. But in your case if you did it backwards it would not matter.

      It can be confusing depending on how you wire things up. The colors and labels (+ or -) on the connectors are meant for how you would wire a single solar panel to something. However, if you start to run multiple panels and wire them in series or series parallel, then all bets are off. My best advice is to use a multimeter and check polarity regularly so you don't connect things wrong (which I have done before).

      8 AWG is the largest you can do with MC4. The crimpers have 3 different sizes they can handle and are built to match the metal internal connectors and not any specific gauge of wire. If it will fit inside the connect, it will work. But 8 AWG should work.

    • @LDSreliance
      @LDSreliance  2 месяца назад

      No. The largest I have ever heard of is 8 gauge and most of the reviews on those said it was BS and that it was really 10 gauge connectors with a seam cut in them to make them open slightly wider. 10 gauge is the largest I would ever run in MC4 connectors. If you have a need for thicker cable that means you are running too many panels in parallel on the same wires OR your wire run is too long. To get around this, use a combiner box. They are cheap and make wiring super simple. You can run big beefy cables out of the output of a combiner box for longer runs, too.

    @ldsreliance quick question, as you get more and more solar panels do you simply keep daisy-chaining them, or do you need to consider a different gauge? I imagine the answer would be different if you were doing it in series versus parallel. Thanks again for the incredibly helpful video.

    • @LDSreliance
      @LDSreliance  4 года назад +1

      Daisy chaining them will wire them in series, which increases the voltage each time. That will help keep the size of the wire down because higher voltage suffers less voltage drop. But there is a point where you will exceed the voltage capacity of your charge controller/inverter. So another option is to use a combiner box. I actually just uploaded a video yesterday about that very subject: ruclips.net/video/MYUm3IwyAkM/видео.html

    Do you have a video on amps, watts and volts? My brain just can't seem to grasp the differences.

    • @LDSreliance
      @LDSreliance  3 года назад

      Not just that one concept, specifically, but I do explain it in a few different videos. The easiest analogy I have seen used is that volts are like gravity acting on balls on a slope. The balls are pulled down the slope of a hill by gravity. The steeper the slope (higher voltage) the more force/pressure is exerted on the ball. Amps is a measurement of volume or quantity. Think of it like how many balls are being affected by gravity. If you have 1 ball or 10 balls on the hill it makes no difference to gravity (volts) because that is the same. But 10 balls is a bigger volume or quantity rolling down a hill than 1 ball.
      And Watts is just the two multiplied together. It is the actual measurement of energy. 1 ball rolling down a gentle sloped hill doesn't have much energy. The ball will be barely moving. You can add 9 more balls on that same hill and they will all be going slowly down the hill and you have 10 times the amount of energy as the 1 ball. Or you could have a much steeper hill that is 10x more steep than the first gentle hill and only have 1 ball but that equals the same energy as the 10 balls on the gentle hill.
      Volts is the pressure or force, Amps is the volume or quantity, and Watts is the multiplied total of the two which equals the amount of energy. Does that make sense?
