[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter

Works great for my solar system. The size is makes it easy to install.

I’ve had this in the field on a trail camera for a year now. I love it shows me voltages and confirms the connections. During January my trail camera went off line. I presume due to low power cut off, the charger caught enough sunny weather that battery fully recharged and camera came back online.

Bought 2, and one was bad out of the box. They replaced it.. Why is everything that's made in China has a high failure rate ? Really to bad.

This is a small but effective controller

I am very disappointed with this product. Unfortunately, I was unable to properly evaluate its functionality because I could not even complete the initial setup. The unit would not enter setup mode at all, rendering it effectively unusable out of the box. The operating instructions are essentially worthless. At best, they explain basic wiring connections, but they provide no meaningful guidance on configuration or actual operation. For a device that is marketed as an “intelligent” MPPT controller with programmable features, this lack of documentation is unacceptable. Additionally, the claimed 100-amp rating is highly questionable. The connection terminals are physically incapable of accommodating the wire gauge required to safely handle that level of current. A true 100A controller would require at least #3 AWG copper conductors, which simply will not fit into these terminals. This raises serious concerns about the accuracy of the specifications and the overall design integrity. I purchased this controller assuming that some of the negative reviews might be attributable to user error. Unfortunately, that was not the case. Based on my experience, I would strongly recommend continuing your search and being prepared to pay more for a reputable, properly documented MPPT charge controller from a trusted manufacturer.

12V load does not work. Trying to warranty the unit with seller who keeps saying I'm connecting my 12v light to USB. Edit: contacted seller regarding warranty and seller offered to refund the purchase. Update my review. Check your unit to make sure it works. But seller is responsive and will make things right.

This works great. The materials feel a little on the cheap side. It works as it's supposed to and has an option to turn the load off which I like alot.

Works well for quick charging

Good product

En remplacement du même modèle qui a été livré défectueux, mais constaté bien plus du temps de la garantie, donc, en espérant que celui-ci sera opérationnel. Défaut du précédent : fonctionne, mais n'arrête pas la charge quand la batterie est pleine, soit : pousse à plus de 16,5 volt.

Para ser mi primera vez con un regulador solar muy bien, súper sencillo y económico. Esperemos que dure.

This controller has performed very well. The LCD display is readable in full daylight, setting are straightforward. I used to charge a marine battery and run an electric cooler.

I haven't got to try it out yet, but taking pictures to show the size realistically. As described!
