I'm wondering if you good lot have any suggestions for a 12V Solar Charge Controller possibly even with MPPT?

I'm thinking something cheap and basic as it's just to play and test with until I have enough cells and panels to get a decent 48v controller.

Any advice greatly appreciated.
 
Hahahha, gotta love auto-translation w/o verification:

The new MPPT solar charging module, strong second CN3722, import IC is the cow!
Input ideal diode anti-regurgitation (3722 series Schottky anti-reflux)
Double Nmos synchronous buck (3722 single Pmos Schottky rectifier Buck)
600Khz higher frequencies (3722 only 300k, big loss)
Solar energy input of the anti-reverse (reverse shall be burnt 3722)

"import IC is the cow"; "anti-regurgitation"; "anti-reflux"; "big loss"; "anti-reverse"; "shall be burnt"


LOL So hilarious! :p

I've had good luck withhttps://www.aliexpress.com/item/Solar-Charge-Controllers-USB-LCD-Li-Li-ion-lithium-LiFePO4-batteries-Solar-Charge-Controller-30A-Free/32426761487.html

It's not MPPT but it's pretty hard to find good MPPT controllers that are also cheap.

You might also like to look at Adam Welch's vid:

Two thumbs up on Adams MPPT. It's cheap to make, parts are readily available. Easily expandable both capacity and function. And the code can be suited to your needs and custom design.
 
Thanks all, I've watched allot of Adams videos, I'll be taking another look before making a purchase :)
