I received this a day or so ago and installed it today. Other than drilling a 3/4 inch hole through the exterior siding of my workshop/storage shed, the installation was a breeze. I put a bead of clear silicone sealer (caulk) around the outside edge as it doesn't come with a seal of any kind. Based on personal experience with outdoor devices and connectors that leave small holes or openings exposed, I suspect I'll put something removable in the two unused connectors to keep the solitary insects from stuffing them full of dead bugs for their unmatched eggs. This is a great connection device to make it easy to connect/disconnect solar cables and to have a neat entry point.
I used 2 of these MC4 housings for an at home installation. I place one outside under an overhang and another in my utility room. I used the included wago connectors to connect the housings together. Now when I want to charge my Yeti 1000, all I have to do is connect to the inside housing and connect solar panels to the outside housing. The cables are robust. The housing is solid, but 3D printed. That’s not a problem but remember that 3D printed plastic isn’t very hard. I did some cosmetic damage to one housing with my drill. I have had some rain since installation, but the outside housing isn’t really exposed to direct wind, sun, or rain. I didn’t even caulk it. I can’t speak to how these housings will hold up in direct sun, rain, wind, etc. For my application, I’m very satisfied.
I built a so called "Solar Generator" and was looking for a way to connect my solar panels to it. I used a big utility box with wheels for my generator, and didn't want yet another connector for my panels. I wanted to stick with MC4 to minimize cables and adapters. This connector was the perfect solution. It is so easy to install and comes pre-wired with 10 AWG wire and quick connectors for up to 50 amps of current capacity. I simply surface mounted this to the side of the box and wired it to the solar charge controller. Now I can connect my solar panels to it by using the MC4 connectors directly from my panels. No need for making additional cables or using more adapters. Minimizing connections is the key. I love this connector. It is very well made (in the USA), robust and weatherproof. It performs great and makes my design much easier to use. This connector is a great value for the price and I give it 5 stars.
As a few other reviews have mentioned, this unit feels and appears to be 3D printed. And guess what - I don't care and neither should you. It's durable and well designed and does what you want it to do - conceal an otherwise open wire entry point. My only reason for 4 stars rather than 5 is that there are outlines for screw holes in the housing but no holes (no biggie to drill your own); and the housing has a channel on the back side that *appears* to be for a seal or gasket. For my application - where the housing was routed into a board to make it flush mount - a gasket on the back side would've been ideal. I can't imagine what, other than a rubber seal, that channel would be for.
This was a perfect item to stick on the top of my solar junction box to connect an extra set of parallel panels. Easy to integrate but remember to confirm that the WAGO connectors are rated to handle the amperage you intend to put through this; in my case it didn't so I just removed them and attached to my bus bar directly. I did apply a caulk seal around the outside to weather seal this and I had to drill screw holes since this does not have any.
