They burned out. We used them to regulate our charge from solar panels

Good solar-panel charge & load controller. Automatically senses if the solar-panels are for a 12V battery or for a 24V battery system (electrical knowledge is required).

This is only my second charge controller. I am kind of new to solar. My first charge controller was like this 100A, but only 30A. I replaced the 30A with this unit to upgrade my solar setup under my gazebo. I do movie nights out in the yard and spend a lot of time out there when I'm not working. I also just set up my second solar system in my vehicle, where I ended up placing the old 30A charge controller. The charge controllers have some similarities. They both have the regular solar panel, battery, and load terminals and USB ports. There are a couple of things I like about this unit compared to the older one. It is compact, it's smaller than the 30A controller. The best part is it has 2 x 2.5mm DC ports. The left DC port is an input where I can connect something like my portable solar table. This will be great when I go camping because I don't have to bring a big bulky solar panel. I can use the 2.5 mm DC output on my solar table that I already bring camping anyway. The right side 2.5 mm DC port is an output for a load. This is amazing because I have a ton of 2.5 mm gadgets and devices. I have lamps, lights, a boombox, a heated blanket, massage pad, etc... That all use a 2.5 mm plug. I also have a few 2.5 mm DC extension cables, so whatever I connect won't have to be right next to it. I won't even have to cut or splice any of my wires to use them with this charge controller. I can't speak on the MPPT part of this unit because I've never opened it up. What I can tell you is that it works great for my needs. My battery is always charged when I need power outside in the yard or in my vehicle. That's all I wanted. It has a nice big, clear, easy to read screen. The controls are easy to use and easy to change settings. It functions a lot like my 30A controller, so I already know how to change perimeters. I had to change some settings to use the 30A with my new LiFePO4 battery that I used in my vehicle. The settings on this new controller work the same way. I've loved electronics since I was a little kid. I've always had gadgets and gizmos. I not only use them but I repair them too. I'm still a newbie when it comes to this solar stuff, though, but I am very happy with my charge controllers. They do exactly what I need them to do, and that's keep my batteries topped off. If you are a newbie like me or just on a budget, I definitely recommend this charge controller. For the price, I don't care if it's a genuine MPPT or PWM controller.

I have the 30A version of this, thy look exactly the same, feel like they weigh exactly the same, there appears to be zero changes to the input ports to allow for a heavier weight cable compared to the 30A version... I do not have 100A of solar to test if this thing would explode, but I do not buy the marketing on this.That being said. I have run my 30A version of this with 300 watts of solar for about two years now. It has been fine, though there is some rusting around the USB ports (it is in a pole barn, but it is an open barn so it does not get direct exposure to the elements but it is still "outside".This one seems to work exactly like my 30A version, menus are all the same, display graphics. I would tear it apart out of curiosity but I need one of them to work so it is not worth the risk. I think if your putting 100A on a solar charger that likely has a $9 solar board inside of it your just asking for it. I think you would be safe at 50A but until someone has the setup to test this I would say -- be cautious.I got this for review to use on another small solar project I have that is not mission critical. It is only 100 watts of solar.The nice things about these charge controllers (aside from price) is they have a nice switched load side output that you can use which will turn off automatically when your battery gets to low instead of draining the battery to the point of where it might be damaged. During the winter we get some weeks of cloud cover which does not let the battery fully recharge, so it is nice knowing it is not going to be damaged by draining it too low (when you connect your load directly to the battery).The USB ports are also very helpful, though they seem to be max 1A between the two of them (tried running a Raspberry Pi off of it and got low power warnings).If you have a small solar project that is not mission critical I think these are great (even if they are probably not MPPT and the input ratings are questionable).

item name: 100A MPPT Solar Charge Controller 12v/24v Current Auto Focus MPPT Tracking Charge with LCD Display Dual USB Solar Regulator Charge Controller Multiple Load Control Modes [Brand: OOYCYOO]item URL: https://www.amazon.com/dp/B0BNTRX8NGHere are some pictures of the 100A MPPT Solar Charge Controller that I received. This is like a little picture gallery version of an 'unboxing' video, but the static pictures make it easier to read all the writing. As you can see, the box is fairly plain and the User Manual is a tiny pamphlet that isn't much larger than the controller itself. The last picture is a close-up of the User Manual in case someone would like to read it before buying or if anybody has misplaced theirs.The Users Manual is a rather small sheet of paper with English on one side and Chinese (I assume) on the other side.The holes for the input and output wires are not large enough to hold wires/cables that could carry 100 Amps, so regardless of whether the electronics inside this box can handle 100A there's no easy way to actually connect it to that amount of solar panels.Unfortunately I have not had a chance to try this out yet but I will update this review when I've connected it.
