CONECTOR MC4 PDF

The terminology relates to the crimp terminals inside the plastic housing not the physical body of the plugs. They are inexpensive, and worth having, especially for taking the terminals apart after they have been closed for a while. You will need a crimp tool for the MC4 terminals. However, as usual, I have located a very good value in an MC4 crimping tool, though not the tool pictured. A pro who does this every day for a living would not use this tool because it is more tedious and time consuming than the more expensive pro-grade versions, which utilize a locator assembly.

The terminology relates to the crimp terminals inside the plastic housing not the physical body of the plugs. They are inexpensive, and worth having, especially for taking the terminals apart after they have been closed for a while. You will need a crimp tool for the MC4 terminals. However, as usual, I have located a very good value in an MC4 crimping tool, though not the tool pictured. A pro who does this every day for a living would not use this tool because it is more tedious and time consuming than the more expensive pro-grade versions, which utilize a locator assembly.

For the money this tool preforms very, very well. The tool represents a decent value for the budget minded boater. Strip Outer Jacket From Cable On boats I will occasionally use a two conductor un-tinned round cable such as an SO type wire for the external connections to the solar panel, but most often a tinned marine grade wire is what I use.

Inside the solar MC4 terminal the use of tinned wire is not as critical as with open style crimps. Once through a deck-gland, such as those made by Scanstrut, and into the vessel, you can switch to a larger GA wire in order to minimize voltage drop on longer runs from the PV to the battery bank. Slide Heat Shrink Over Cable To give the wire a nice finished look and feel I slide some adhesive lined dual-wall heat shrink over the wire.

I prefer to have the stripped wire extend very slightly into the barrel of the terminal a bit. This ensures it does not fan out when crimped, and create issues when inserting it into the plug. The open wing-ends of the terminal face up towards the butt cheeks so it can be rolled over and formed to execute the crimp.

TIP: It helps to compress the crimp frame just a click or two. This will hold the terminal as shown and you can then insert the wire and finally squeeze the handle to complete the crimp.

Professional level MC4 crimp tools such as those by AMP, Rennsteig and others, use a locator that holds the terminal for you. This picture illustrates why I like to see the stripped wire extend into the barrel slightly. Keep pushing until you feel or hear it click. This means the positive wire on your boat will get the corresponding male plug not another female plug. They literally get to the point where the plastic is crumbling.

As far as our testing shows, there are really only two legit players in the solar connector market. Connectors from anyone other than these two manufacturers should be considered suspect. MHT is now stocking these hard to find in small quantity terminals. The gray colored sealing gland not all brands use gray should be in the terminal as shown here.

Background[ edit ] While small solar panels used for battery charging and similar tasks may not require special connectors, larger systems normally connect the panels together in series to form strings. In the past this was accomplished by opening a small electrical box on the back of the panel and connecting user-supplied wires to screw terminals within. Additionally, these sorts of connections were subject to problems caused by water leakage, electrical corrosion and mechanical stress on the wires. Starting in the s, a number of companies introduced products to address these issues. In these systems, the junction box was sealed and two wires were permanently attached using strain reliefs. The cables ended with push-fit connectors that met the definition of a convenience receptacle, meaning they could be legally connected together by anyone.
