This adapter does the job and is well made.

Reviewed in the United States on May 15, 2015

Verified Purchase

This adapter worked exactly as described (and as explained in the questions and answers section of the listing). The spread between the widest part of the "Y" formed by the four connector cables is about 36 inches -- so, with the 12 to 24 inches of cable that come off most solar panels, it is no problem to use this adapter to span four panels and tie their combined (parallel) output into a single output cable, which you can then route back to your solar controller. The single output wire from the adapter is thick enough to handle 20 amps of current, and could even be pushed to a bit more with no problem.

I am using this set to connect 4 of my 24-volt, 130-watt. 4-amp panels to my charge controller and everything works well. You can save a lot of money by only having to run two cables (one positive and one negative) from the panels back to the controller.

I bought a four panel solar system and wanted to wire them in parallel. These cables made the job very easy. It reduced all panel wiring down to two wires that go directly to the solar controller and then to the battery banks. A very good, well made product.

Super Awesome! Very well made and easily connected my 4x100 watt panels together - a breeze! I really like the small eyelets where the four cables come together. Makes it easy to zip tie everything nice and neat.

This was a great purchase. I caught the Y Branch on sale for $16.99 via Prime. Retail is usually $49. Very happy with this product and recommend to all!

Great solution to a problem that many boondockers face.

Reviewed in the United States on July 5, 2016

Verified Purchase

I got these after the solid adapters I was using to wire my panels together broke in a windstorm. The pressure when the panels blew over was just too much for them, so I wanted something more forgiving.

I'm really happy with these adapters, although the fit on the MC4 connectors is a bit sticky. I don't want to ding them a star for that, though, because they've made having the panels wired up together more convenient by a long shot. I can move a single panel without worrying about the others so much. Since I boondock in the desert, and need to track the sun with my panels, this makes that chore easier. I would definitely recommend these.

I found this product to be helpful for my setup. I generate on average 25 amps with four panels. I gave this product five stars because of the amps I generate. I'm using these cables in a LifePO4 setup.

Watch the current rating before buying

Reviewed in the United States on July 6, 2017

Verified Purchase

These were easy to install and work well. The only reason I take off a star is that the amperage is only 15. It is hard to find 4 panels wired in parallel that will yield less than that. In fact, it looks like most of the buyers here are using them with 12v/8.3amp panels meaning the rated current is being exceeded. This is dangerous. It is a good example of buyer beware but by the same token, a more prominent warning or examples of applications where this would work might be helpful.

Makes for a clean and reliable installation

Reviewed in the United States on March 10, 2015

Verified Purchase

I had been daisy chaining splitters as I purchased new panels (1 or 2 a year for a couple years now), and finally decided to swap them all out for a single connector. I'm really happy I made the switch; my peak amperage is up and my charge controller doesn't shut off as early in the evening, so it looks like there is a measurable decrease in voltage drop as well.. The MC4 connectors are solid, seal tightly with an audible/tactile 'click', and can be removed without a tool.

Get the tool to separate the connectors also.

Reviewed in the United States on September 16, 2019

If you are using these where you do NOT have to disconnect, then Great! BUT, if you use them on a portable unit(s) that you want to be able to move as needed, then you may want to order the connect-disconnect tool right off the bat with the cables. My hands and wrists hurt so bad after trying to get them apart. I couldn’t do it. Even the installer had to use a pliers to get them apart. I will go a bigger size connectors and get the tool also.
