[Upgraded] 30A MPPT Solar Charge Controller, 12V 24V Dual USB Solar Panel Battery Intelligent Regulator with LCD Display, Auto Parameter Adjustable, Timer Setting, Multiple Load Control Modes

Lasted a week now output is varying from 6 to 8 volts. Tested woth multiple sources and multimeter (initial concerns prompting testing was the facts my batteries dies with solar panels hooked up in sunny weather

I am a DIYer who builds a of 12v rechargeable devices. I got this charge controller to use with the outdoor surround sound system I'm building for movie nights. I haven't finished the build because I'm waiting for the speakers to arrive. This is my 3rd charge controller of this kind. I do movie nights out in the yard and spend a lot of time out there when I'm not working. This unit has the regular solar panel, battery, and load terminals plus USB ports. It is compact, it's smaller than my old 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 panel. This will be great when I go camping because I don't have to bring a big bulky solar panel. You will notice in my pictures I have MC4 connectors installed if I want to hook it up to my bigger solar panels. But they are unplugged because I'm using a 2.5mm 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. 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 100A and 30A controllers, so I already know how to change perimeters. I had to change some settings to use this with a LiFePO4 battery. The settings on this new controller work the same way. If the brand doesn't matter or you are on a budget, I definitely recommend this charge controller. For the price, I don't care if it's a genuine MPPT controller or not. My other unit like this has been working great for the past 4 years and still going strong.

instructions in no better words then suck's.

This controller does work, but I find it very hard to believe that it could handle 60 amps in a package this small with almost no heat dissipation. I'm also suspicious of the MPPT claim rather than the cheaper PWM.Upon taking it apart you can see how simple the design is, without any large capacitors or inductors you would see on brand name controller. I also noted the poor quality soldering job and the piece of solder/component tab material that was bridging to exposed traces. Good thing I took it apart before trying to use it.

Not 100 amp, maybe 100 watts

I've got the product in March of last year. Well I have to get a new charger. It quit work. No even a year and it stop working. This sucks. If you want long term. I wouldn't suggest this. To get you by, sure. Don't drag your feet.

This is the third solar charger like this I have, going from 30A to this 100A version. All of them feel the same weight, I think it is probably something small inside that is different between the three. Of the three I have really only two complaints. Setting these up for anything other than Lead Acid batteries is a chore -- and I am still not quite sure if I am doing it correctly (setting up for LiFePo4) but my projects run so I assume it is working correctly (setting charge point / float / load settings).The other complaint I have about these is that the USB ports, will eventually rust and either make you clean them or lose them. Most of my projects are housed in those battery boxes you get for about thirteen bucks at walmart so, while they are not directly exposed to the elements, they are out there in the elements. I think these are meant to be in a more protected enclosure.The lonest running project I have with one of these is the 30A version, it is connected to a 30 watt pannel to keep a 12v 7ah battery charged for a WiFi camera. Has worked flawlessly.I have a 60a version of this and it works great, 20 watt panel with a 12v 6ah LiFePo4 battery used to keep a WiFi repeater going. This one is going to be connected to a 100w panel and 12v 130ah battery (deep cycle car battery) and run a repeater, two cameras a few sensors and a microcontroller (15 watts).I am not sure that these are really MPPT, because I have gotten documentation with them that read PWM MPPT, though I suspect it is PWM because at these prices it would be incredible if it were true MPPT.For small solar projects I think these are great, I would have a hard time trusting them with anything mission critical or larger solar inputs. If you are just getting into solar then this is a great starting charge controller.
