LiTime 30A MPPT Bluetooth 12V/24V/Auto DC Input Solar Charge Controller Adjustable LCD Display

Lithium default is excellent I recently upgraded to lithium batteries in my RV. The OEM solar controller made by F*unyun worked fine with lead acid batteries but with lithium it would reset to LA function every night when the controller went dormant. The next morning I would have to reset it to lithium mode again. Not so with the LiTime controller. It works flawlessly with my panels. Mounted easily, has a programmable dc load output, and shows what my system is doing via bluetooth. Hard to beat at this pricepoint.

Great product LiTime is a great company with high quality products.

The controller is basic looking but appears to be of good build quality and the bluetooth app works great with all of the need to know information. The outer case of the controller is covered with a type of rubber coating that I'm sure is there as a protective coating but it also makes the controller easy to grip while handling it. I've only just installed it so time will tell if it's as good as it appears but the price was right so I think it's worth a shot.

LiTime 30a/40a Great controller best buy would buy again if needed Easy to set up.

Works great So much easier to use than the previous one I had.

Havent wired in yet will wait till spring,snow on the ground right now. Bought the 300amp battery,40amp charger and the 30 amp mppt controller all look great in the quality of these units

So far it has performed as expected, have been charging my 2-100Ah batteries without any problem. I will definitely will be purchasing the 60 amp charge controller so I can use more solar panels if needed.

Great product thus far. The 30amp MPPT is working as advertised.

12/24 volt 30/40 amp mppt Seems to be doing the job. First time using solar and any setup like this. Not enough explanation for screen information in pamphlet sent with product so patience was key. Only gets warm slightly. Working with 365 watt panel and 2 sealed lead acid batteries ( 75 amp hr each ) probably 10 days now. We'll find out about longevity and the screen explanations would be very helpful so only four stars for now.

40 amp controller Installed two days ago and it will not power up, just blank screen. There is 12 volt power (13.3 v) tested to the unit. Can you help? do you think the unit is faulty? Any help is appreciated
