[Upgraded] 30A Solar Charge Controller 12V/ 24V Solar Panel Charge Controller Intelligent Regulator with Dual USB Port Auto Parameter LCD Display and Timer Setting ON/Off Hours

The best

it works.. I dont really know how to k use it yet.. but it came on when I hooked it up.

They will eventually croak out, however they are cheap and fast to change out. Moisture is your enemy, their failure is likely my fault for not having enough protection for them in remote locations.

I bought this to trickle charge my battery. The charge controller quit working in less than a month of use. Return policy of amazon has changed which make it harder to do. I think I will take a break from amazon after this. Good luck every one.Update 09/06/2023: seller reached out and offer options to refund or replacement. I elected to give it another try. Kudos to the responsible and motivated seller. Review is now 3 stars. Lets see if product last....if it does, I will comeback and update my review.

I was burning up batteries. Turned out the old controller had gone out. Been a year now and no problems with this on my automatic gate.

This product appears to go out consistently with any significant amount of power. I have a solar panel that runs 32 volts @ 5 amps. I used this with a 24 volt battery. This first one failed by charging for a few minutes and then stopping once warm. I thought that this could have been caused by a battery disconnect momentarily while having an active panel. The product warns of this. I replaced it and realized that it was happening again after a month. Using this controller with a 24v panel and a 12 volt battery is even worse. If the charge rate is around 50 watts or less, it's not a problem. I did not know what my wattage was on this because the meter did not work on either one. I also, would like to add that my battery never reached a full charge with this controller. I just upgraded to a 60am mppt charge controller and I am amazed how everything works. My batteries were fully charged and sustained use for hours without sun. Spend the extra $10 and get the 60amp.

Product works as it should. Very nice compact unit for what I needed to do. Great Customer service will always get 5 stars. Answered my questions very quickly.

Works yes but to small , not as described
