[Upgraded] 30A Solar Charge Controller, Black Solar Panel Battery Intelligent Regulator with Dual USB Port 12V/24V PWM Auto Paremeter Adjustable LCD Display (30a)

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!

I bought this as a Stop Gap to Keep a High Dollar excavator Batter charged up in a remote site/ I thought this think was Junk and would Fail way befor now. It did work out of the BOX, I left it hooked up in the Boon Docks( East Texas swamp) Its still working. Hooked up to a 150 Watt Panel. its Good. Cheap junk that just works.

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.

Worked well with my panels to provide 12v to charge rv battery and cellular usb devices.. with no ac around

I bought this item for use on a small boat with 2x 100 watt panels in parallel. On a great day I get about 12amps, so usually much less. The RENOGY panels came with a 20 amp RENOGY charge controller that was damaged by a faulty voltage regulator on my alternator. I thought buying a 30amp regulator would mean longevity since I would be barely using 50% of it's capacity. I also fused the circuit to the battery at 20amps, so 66% capacity. The charge controller failed internally. Being in a remote location on a boat, I chose to disassemble to attempt a component fix. The MOSFET transistors are NOT thermally bonded to a heat sink. The transistor simply over heated and died a smokey death. The MOSFET for the load circuit is the same as the battery circuit, and I don't use the load circuit. Even after moving the MOSFET over, it would still not turn on - so I would assume some other component died as well. The back cover is aluminum, so manually bonding the MOSFETs could likely make this unit last longer. The controller would not keep a precise float voltage, causing havoc with my charge warning system for the alternator. With very bright sun, it would over-run the float voltage sporadically.

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

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).

Perfecto funciona.

Funktioniert wunderbar

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
