Overall this is a nice cable and works great to allow me to get solar from my panels to my power stations in my garage. Thick gauge. My critiques are that the MC4 connectors used feel low quality and are difficult to disconnect. Most of the other MC4s I have, have tabs on the side to help release the locking tabs to make disconnecting easier. Also the male/female connectors are backwards and don't match up to my solar panels correctly based on the wire coloring. I had to use a multimeter to check this and confirm that they are in fact swapped. I will likely cut the connectors off and put on new MC4s so the polarity is correct.

Can't argue with what you get for the money. A tracking system for less than 1K is pretty good. I loaded mine with 8x old 50W panels. They crank all day long. My workshop is off-grid and the panels mounted on here are doing WAY better than the 8 you can see in the photo. The pad I mounted it to is 2x2 on the top and goes down 3 feet. Our dirt here is VERY hard and almost like compacted gravel so it's not going anywhere. The good: Easy to put together. Plenty sturdy for our winds with wind sensor. Included unistrut stuff is easy enough. Tracks very well, within its limits. More below. The bad: Stainless hardware requires you to either use anti-seize or watch your torque. It is easier than you would think to make the hardware unremovable. Tracks well but the southern extent of travel is a bit lacking. I am in New Mexico and I don't think it'll actually be able to pull down far enough to actually track 90 degrees to the sun for peak winter. The neutral: Would be nice if the control pad could easily be mounted the correct way. The manual says to keep the wires coming out the bottom and then you have to mount it turned 90 degrees. I am not too concerned about this as it doesn't rain here much but might be a problem in a wetter climate. Build looks a bit loose in the wind but it is holding up great and doing a good job so far. I've had this installed a month now and it is working well. Gets confused on cloudy days but quickly corrects itself when the sun comes back out. My next upgrade will have to be some newer, higher-efficiency panels for this thing. The 400W array is cranking out what it can for power so I'll need to find some of these infamous Chinese super cheap panels in the US to give me closer to 1000W on this backyard sunflower.
