60A MPPT Solar Charge Controller, 12V/ 24V Solar Panel Battery Intelligent Regulator with Dual USB Port, LCD Display and Timer Setting ON/Off Hours

With the world moving to alternative power, and constant breakdowns of our existing power sources, I have been looking to other means of keeping my family able to sustain ourselves in case of emergency. So I have been gathering parts to build a small array. I am not totally sure I want the panels on my roof. I lean to the idea of self sufficiency as opposed to large bills for maintenance and repair. This item was economically priced, and it is one of the pieces you have to have in an array. I like it because it is simple in nature and you don't have to be a genius to make use of it. All the points are clearly labeled as to what goes where. you have 2 USB ports and a clear digital read out. It is lightweight, but does not look cheap or carelessly made. I feel confident in my choice, and believe this will be useful for a while. as to how long that remains to be seen. This works for a small array, with direct contact. It's success will lead to larger things requiring a battery for storage. We shall see!

For $10 this has worked great, I've got a 100W harbor frieght panel set ontop of my truck cap, two duralast platinum AGM batteries and a 500W inverter that runs full time. This is the 3rd controller I've tried and after 2 years this one actually still works great keeping my trucks batteries topped off when it sits during the week and in direct sunlight im pushing about 7.8A at 29VDC from the panels and getting 4A at 14.4V output. Works great for the price and is tiny so it doesnt take much room

Easy to use, note that this controller is for leadacid batteries only, not lithium. Works well, no apreage reading, just voltage of battery and PV.

5 stars! It does the job for the rock bottom price of $10. Be amazed! Ok, here is reality. I have used this unit for 7 months to experiment with a 100W system. It regulates the charging of my very nice no maintenance lead acid batteries. It knows how to do this and most of the time it also knows that I am setup in 12v mode. 1. Do not use the 12v extension or the 5v USB connections. They really are not functional for any reasonable current output. The board will stress, a resistor heats up on the board and the LCD will blink out temporarily. I have not fried the board but I would advise connecting all power draw, USB or otherwise through a fuse block directly from your batteries. Sometimes the controller decides for no good reason that you are in 24 volt mode. This isn't good because it seems to happen when my battery is almost fully charged over 13V. That means it will try to overdrive well over 14V and possibly 6 or more amps into a full battery. This is no good. If you catch this your first easy sign is the battery charge picture will say barely charged... Disconnect the solar, then the battery... Wait 15 seconds then plug the battery back in... Carefully connect your solar panel. Pray it stays in 12V mode At the moment I unplug the solar panel when the battery is mostly charged and the system decides that it's 24V. I am only using this as a test bed drawing small energy for 5V USB networks at the moment. When I get serious and add more power and a proper converter I will pay good money for a real controller. So, great for the low price of $10 , great learning tool but pay real money if you want a reliable system you can count on.

I connected the charge controller to a 12v deep cycle lead acid battery on my boat, then connected a 130w solar panel. Next I plugged a cord into the one of the USB ports, and into my phone to charge it. Within a minute White Smoke Started Coming Out Of The Charge Controller! I immediately unplugged the phone and watched the unit. After disconnecting the solar panel, then the battery, then reconnecting each and watching the unit carefully after ever change, I observed that the unit smokes soon after a phone or power bank are plugged into either USB port. It MAY be a settings issue, but honestly I don't care what the reason is. The instructions on how to set it are unclear and if there is ANY possibility of the unit catching fire due to incorrect settings settings then it is not worth the risk of keeping the unit. I'm requesting a refund immediately, and will have to spend a bit more for a better unit.

LIKES: The "set" charge voltage was exactly 14.4 on a deep cycle marine. or 2.4 volts per cell. According to Battery University a perfect float voltage for this kind of battery.. DISLIKES: THESE ISSUES makes the whole product a THREE STAR and it could be a FIVE STAR with more attention to install and operating instructions. EXAMPLE: BTW there is no information on what wire gauge to use. A SERIOUS FAULT. Found only in a user question (BTW, AWG12) Instructions are nothing short of Horrendous. You have to go to many YouTube vids and view several to get the correct steps as each YouTube presentation has it's own problems with explanation. I found none that told the whole story. . The 4 icons do not have any use on the unit except adding confusion. They are not interactive as they seem to be. Briefly, push left MENU button repeatedly to arrive at the setting that you will use. Then hold that down until it flashes. 5 to 12 seconds. At that time the + and the - keys will operate. I still do not have it all figured out but when I do I will post it. INSTALLATION: The entry holes for the insulation and wire are barely large enough to insert AWG 12 with some insulation. I used AWG 10 for extra "load " protection. Therefor only the bare wire passed thru. Overbuilding works well, until it doesn't. Open the inside wire clamps before inserting using the screws on the front panel. It looked like they already were open BUT alas..... they are not. Operating continually now for 2 days to a double panel, 340 total watts and all seems fine.

I am using this device along with a 100 watt Coleman panel I bought from Canadian Tire that came without a charge controller (thanks for nothing Coleman! 🙄). Works exactly as promised/described on Amazon's listing. I like that I can configure the output power level to the battery, the charge level and the cut off (battery full) level myself (for now I've left them on the defaults). Very simple to use & adjust. The accessory 12v power output connector is an interesting idea, but as another reviewer mentioned, it seems to come on and off on a whim. I was under the impression from the instructions that it would turn on when the panel was inactive (at dark), and back off once it was charging again (when sunny) when set to 00. But when I tested this by disconnecting the panel to simulate dark, it came on and stayed on after the panel was reconnected. Weird. There is some kind of timer control to it, I didn't really explore it much more, but you can set it from 00-24. Does it just count time down from the setting once you set it? Who knows, there is very little information about it in the instructions. (As is typical with Chinese products purchased on Amazon). The USB outlets charge at a reasonably fast rate (my Samsung phone was at 39% & claimed it would be fully charged in two hours). The only other concern I have is regarding those very USB outlets. They are active even when the panel is disconnected (ie: when only the battery alone is connected). This tells me they are drawing and converting 12v from the battery to 5v for the USB outlets constantly. I suspect this could lead to a slow vampire draw on the deep cycle battery when/if the system sits idle without any panel connected to it or at night. But if you always have a panel connected, that shouldn't really matter - the daytime solar charging would likely more than make up for it. I was getting 13.1/13.2 volts into my battery under a heavy overcast sky late in the day, my panel was putting out more than 18 volts at the time. I definitely highly recommend this simple little controller, I'm completely satisfied for under $20 (including taxes).

Einfache Installation , funktioniert prima

Funkar perfekt. Lätt att förstå och lätt att installera.

Je déconseille, na pas fonctionner plus d'une heure deja HS, port de charge usb défaillant, à fait cramer tout le contrôleur, article à éviter

I wanted to set up simple solar lighting arrangement in my garage. I already have a similar set up and find these controllers good to ensure I have a charge and control the input from the panel. It is working really well and it does not cost too much so all good so far.
