[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 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).

Einfache Installation , funktioniert prima

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!

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
