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

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, although not efficiently, with 12v panels. It's easy to use although has no setting for Li batteries. I use one for 12v LiFeP battery and it works fine. You can set the voltage for charge and float. USB outlets control voltage at 5.1 v regardless of battery volts (anything from 10.5 to 14 on mine). Worth the price for the controlled USB voltage from a 12v battery.

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.

I used this on a retrofit hot water heater that I used a 12 v RV. water heater element on. It's running off of a 100 w solar panel so far. (I will be adding more later). I'm starting with the highest power usage items first. Then eventually work down to the lowest like the refrigerators. next on the hit list is the electric clothes dryer. I'm building this to run off of a diesel parking heater. this will save a ton on electric. I run these on dyed diesel @ $18.00 for 5 Gal. mixed with used motor oil or kitchen oil for more savings. this way I can stay with low voltage. this unit seems like a pretty good build quality with a lot of features and it's compatible with most 12 v parts. I like the display and it's easy to install. I am planning on buying more of these as I build up my system.

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.

I added one solar panel to a remote building using this charge controller, a deep cycle battery, and three LED lights. It works great. I can also charge my phone with it. It is programmable as to cut in and out voltage. Highly recommend this.

I bought a few like this ~10 years ago, couldn’t find the same listing, so I purchased this one - and they work, but they are not great: Pros: it works to put solar electrons into batteries Cons: the volt meter display isn’t that accurate, it’s only really 0.3VDC off, but one of them is off by +0.3, one of them is off by -0.3, which is more of a nuisance than anything, but it’d be better if it were consistent — additionally, it may charge the battery poorly based on being off by that much, overcharging or never fully charging, not dangerously, but enough to degrade the battery early. The load on-off button press is very inconsistent, again, mostly a nuisance, but it can’t be set-and-forget due to that, and the 10-yrs-ago version still works better For $10-ish ea, they’re worth the money if you have a very simple setup, or need one-per-battery for balancing, but if you need a higher reliability setup, this might not be for you

Works perfect on my cargo trailer. I connected the charger controller to my solar panel and a marine battery, plenty of charge all the time. This controller allows me to change setting for my needs.

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.

Ottimo

un grand classique indispensable. fonctionne très bien et longtemps, attention a bien lire le mode d'emploi, brancher la batterie d'abord puis le panneau

Excelente funcionamiento, precio accesible y me ha solucionado incluso para mantener cargada una batería en un vehículo.

Good simple functional moot charger that shows amps in true time and amp hours used One of the best in its price range
