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

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.

This 60 Amp MPPT solar charger is working great at managing my small array of 8 x 100 watt panels charging 4 x 100Ahr LiFePO4 batteries. I see some negative reviews and wonder if proper setup was done. The owner manual says maximum input voltage from the panel is 23 volts (many panel will exceed this voltage, so check panel voltage ) and there is a specific setting for charging LiFePO4 batteries. See my pictures. I had this unit online for less than a month. It does get warm mid-day when there is about 35 Amps coming in from the panels. I will update with longevity.

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 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.

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).

Fantastic and robust. Highly recommend

Funktioniert wunderbar

Funkar perfekt. Lätt att förstå och lätt att installera.

These are inexpensive but it does the job, they are not the most efficient type but for what I am using it for on my motorhome it does the job, it trickle the leisure battery when we are not on mains, assuming the sun is out of course, which helps to keep it topped up. It is straightforward to connect and the display lets you see when it is or is not providing a charge.
