Very nice and much better than expected
Working very well, and the amp reading is also very nice to have, let me know I wasn't getting as much power as I should be, upon checking I found a bad connection that was causing almost a 75% loss in amperage that my old charge controller showed no indication of. Follow up, as well as it was working it died at 34 days. This is 4 days outside the Amazon return window, considering it took a few days before I could install it it actually worked for less than 1 month. Who knows maybe I just got a bad one I will order a replacement. Stay tuned for info on replacement. Replacement wasn't needed, I disconnected it for about 30 minutes then reconnected it again and it appears to have reset itself, it is currently running just fine and all readings I have verified are again working spot on.

Works well
I didnโt want to spend much $ to set up a system I wasnโt โsoldโ on. This unit was a cheap alternative. I used all summer sailing. Worked perfectly. Concerned about the longevity. Priced others. Bought a second one to back up. Much cheaper solution.

came with a 12v solar panel package I bought.
The highest you can set it to stop discharge to load is 11.3 volts. Too low if you plan to have it running for any length of time. If you run the load intermittently, it works ok.

set up for L-ion battery
Need clearer instructions on how to make changes in settings.

Instructions are easy to understand
Has amp meter built in and the instructions are clear to understand. I'll be buying more as I get more panels

100A not really
The device overheats at 24V/28A the wire terminal only accept 10 awg good only for 30A. I got the 100A device and no, it will not work at 30A. I have a 1100W solar panel arrangement It should work up to 2400W, actual about 800W when it was overheating, I will have to return it. It is not LiFePO4 capable either, There are several models and rated Amps I think the only difference between them is the sticker that says the Amps and the only real model is the 30A that may work to 25A so you might be able to connect a 300W@12V or 600W@24V
