Renogy Solar Panel Connector Assembly Tool

This worked great for disconnecting solar panels while working from the roof. Once you get the proper angle, it will be easy to use this tool. Also having two was good because I ended up dropping one and used the other that was in my pocket.

For two tools, they are a great price and they are the only tool that is spaced close enough to work on the MC4 connector of my panels. Even though the plastic tabs can break (one of my first two did break), it is nice that the tabs bend a little so you can fit them in you connector if the spacing isn't exactly perfect. For the price, they are great.

I purchased this Renogy tool because I was unable to disconnect the MC4 connector wires that connect my Renogy solar panel to my Montek 1000 solar generator after it had been outside charging for several days in the hot Texas sun. These connectors are always a challenge to disconnect, however I had done it successfully with these same cables several times previously. This time nothing I did would get them apart, so I bought this tool. With much effort, I was able to get one of them to disconnect with the tool, however no luck with the second one which is still stuck. I'm thinking maybe the intense heat (over 100 degrees every day) may have melted some of the plastic together or some of the wires inside may have melted together, so it may not be the tool's fault. Maybe if I had the tool initially and disconnected the wires earlier on that I may have avoided the problem I have now. The good news is that the solar cables still operate normally to charge my solar generator from my solar panel, so I am just leaving them connected until I can take the time to get new connector ends, then cut the stuck ends off and replace them. I saw a couple videos on how to do this which looks fairly easy. Meanwhile, this tool does work for disconnecting MC4 connectors as long as they are not melted together. It is still an effort, but it will get the job done. I will keep it and use it for assembling my new connectors, which this tool is also designed for, and will update my review to include how well it works for that.

The basic solar connector provides a secure, waterproof connection between solar panels and external wiring. If you need to disconnect them, it can be a challenge. This tool makes it pretty easy. That's my primary use for this tool. I keep one in the battery box I charge with solar panels. Once I'm done and breaking down the setup, having this tool available makes the job much easier. I typically do not assemble solar connectors onto cables, but this tool would make that much easier also. Sure, you could grab the nut with pliers and tighten, but you run the risk of slipping and damaging the connector. One of these holds the body securely as you use the other to tighten the nut. No risk of damaging the connector, no slip, and no leaks. It's the right tool for the job.

Tools are very cheap plastic. Broke an end prong and a down prong off the first time I tried to use them, and I was being careful. Try to find something else, would not recommend spending your money on these.

If you are going to be connecting and disconnecting MC4 connectors this tool is well worth the small price. It comes as a 2 pack. The plastic is a very hard resin type and worked great for me. I had around a dozen connectors that had to be redone and w/o this tool I would need to resort to a pair of needle-nose pliers, and small flat-head, and a lot of cussing ha ha. HIGHLY RECOMMEND. I plan to order a another set or two to have on stand-by just because the price is good and the quality is excellent. Not a cheap piece of junk at all. You will be quite happy to own this product.

Does not fit all connectors, including the ones I bought from Amazon. Too narrow to even fit over the arms of the connectors. Ended up just using pliers which is a problem if doing a lot of connecting and disconnecting during system setup and testing.

I love it when products perform as expected, are reasonably priced and are well made. That is the case with the Renogy MC4 Assembly Tool. This tool is composed of a lightweight durable hard plastic. There are two included in the package, so for the price, they are a good buy. I purchased this in order to assemble the connectors on our solar system, and it allowed me to do so easily. Just a side note, it fit easily into a woman's hands, even though when I researched it, most of the reviews had been left by men!

Ottimo prodotto , fa egregiamente il suo lavoro

No son 100% compatibles con MC4 originales... no sujetan firmemente la tuerca y es imposible apretar con fuerza. Para desconectarlos si cumple, pero para apretar las tuercas, casi lo más importante, no

As described

MC4コネクターを外すとき、手でやると、すごく手間が掛かります。 工具を使うと、引き抜くことや、コネクターの交換は楽にできます。

Se ven fuertes, muchos otros acesorios son debiles y se rompen en la parte que se usa para desconectar los MC4, este si se ve fuerte, solo que si cuesta algo de trabajo acostumbrarse a usarlo
