[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.

This is a small but effective controller

I got sidetracked and have not had a chance to hook this up to test it. My initial impression is that it is a well-built controller, but at the light end of power handling capability. The three regulators are not particularly well heatsinked to the back panel. I will update the review, but if you want anywhere close to 30 amp draw, test first. I would be inclined to add a heatsink to the regulators, which would be easy to do in this case.

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.

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.

It's small, lightweight, and cheaply made. The instructions were disjointed, seemed lacking, and at first, they said "This controller is only applicable to lead-acid batteries." This would have been enough to pass this by, but now I had it, I went and looked up the [Upgraded] instruction sheet. There were instructions for picking the type of battery, including Lithium ion phosphate. The other problem I have with these is the size of the connector slots. I hard a really difficult time getting 10 gauge wire from the panels installed and *staying in*. This is where the controller FEELS cheap. and the tiny set screws almost required a set of jewelers drivers to tighten them down. I'm still waiting for some of the items for this build to arrive, can't really write a product review until they can be tested, I finally got the deep charge battery, and all I had to spare for wire was 12 gauge to wire the controller to the battery. Since I just wanted to make sure the controller wasn't DOA, as others reported, I decided to go for it (the inverter had its own cable). I was expecting the wires to get warm when I energized the circuit, but other than a few 5V items, I just wanted to see if the panels would feed the controller, the controller would come on and allow me to set battery type, and check the voltage, the inverter would turn on, and that was it. Since it was late in the day, it didn't really charge the battery, but everything appears to work with no heat from the undersized wire. I'll test that as I put the system together with bus bars, a fuse box, breakers, and safe wiring size. But seriously - just because an item is cheap doesn't mean it shouldn't support safe connections using the correct wire gauge (which in this case would be 8 AWG from the controller to the battery - and I bet it wont fit. The bottom line is this: I went cheap on a couple of things, since I'm building this out for a camper from scratch. It not a bad controller, but from reviews, I don't expect it will last long and this is the first time for building one of these, so when it fails, I'll go for an MPPT controller, likely at ten times the cost.

Works well for quick charging

Bought it to charge my car. Hooked up the battery then solar and set the right battery type. It slowly drains my battery until dead every time. And now my truck dies under acceleration. Do not buy. All it’s safety measures were faulty from the start and caused me quite a lot in damages. Terrible don’t buy.

Ein schöner, kleiner Regler einfach anzuschließen. Er funktioniert wunderbar.

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.

This worked fantastic. Easy to install

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

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
