100A MPPT Solar Charge Controller 12V 24V 36V 48V LCD Display Battery Intelligent Regulator Max 100V Input Dual USB for Lead-Acid/Lithium (100A)

After three months of installation, they operate with no problems, even in the shade of Arizona's heat. I ordered them because they have the larger screw in ports for the 10 or 12 gauge wire, solid body, good heat escape fins on the back, and an easy-to-use button. And most of all, I run 3-- 20-amp 12-volt system, so I buy equipment that will handle at least twice the load I put on it, instead of like my neighbor, who underbuys and burns his crap out. Everything is excellent about them.

Work good easy to install

Last 3 months then stopped working. Tried to reach out to seller with no luck for a replacement. Guess product is only good for 3 months.

Display panel is not as bright as shown. Seems to work quite well.

The size was bigger than expected from photos but it was a happy thing to find full sized screws and large holes to put in pretty big sized wires. Not sure of size. Screen is a little small but tells the tale. Easy information update with no confusion. My amateur wannabe engineer says put washers or just strips of metal where mounting holes are so no breakage in hard conditions. The case seems brittle plastic instead of forgiving but for price, especially if wattage and electronics are good inside, is a real treat. Happy to have bought it. Others reviewed it okay. One one is better.

Bought this because of the higher amp rating. The "instructions" are not even close to thorough. Rufus had better instruction, but I still haven't been able to program it to my specific battery type, etc. I do like the wire connectors, but I'm not so sure about the rest. I don't know, Amazon, sometime the 30 day return policy just isn't enough. Forced to keep it, so it'll be a backup. I don't trust it to stop charging as it said it was charging even though I just unhooked the batteries from my other controller (which works).

Arrived on time works great easy to install good display
