Renogy Solar Panel Connector Assembly Tool

Work as designed.

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.

I found this tool to be most helpful when dealing with disconnecting solar cable connectors. The plastic seems quite robust and it is designed well with multiple functions. A good value for an essential tool,

The tools I received did not work with the MC4 connectors on my solar Renogy panels I have. I had to sand a bevel on the prongs to allow it to fit and open the connectors properly. It appeared as if the tools were just never finished coming out of the molds.

If using portable solar panels where frequent connecting and disconnecting is needed, these assembly tools are really hand to have on hand to make it quick and easy.

Tool works perfect. As confusing as the description and photo is, you will get a PAIR of these tools per order, not just one.
