I have 2 of these and they're not bad for the price, and you can get support. The first one I got had an accident when I dropped a charger accidentally on the LED screen and cracked it, making it impossible to see anything, although it was still work as configured, so I ordered another one and asked for a replacement screen for which they asked $20 and it arrived a bit later. I tested it by charging a Tesla in the field with 12 solar panels and pulling about 1kW into a 2kWh lipo pack made from four 13S scooter packs. I found that drawing power from the load terminals caused it to start smoking, so stopped and drew from the battery instead - no problems. The load output isn't designed for high power! Now I have both working and more panels, I can use it with 2 x 2 strings of 7 x 100 W panels and charge a 5kWh 16S LFP pack at nearly 3kW anywhere I can lay them out!

Excellent, thanks for sharing this information.

it's a clone or re-badging of a Makeskyblue controller of which I run 3. The default lithium profile will low voltage overcharge your battery as 13.8 is way too high for a float voltage, which LiFePO4 doesn't need. 13.5v should be the upper limit if you have to have float. The Makeskyblue version has proved itself to be good over the years although some of the clones have less than brilliant tracking with a tendency to hold panel voltage too low.

Thanks for the info, I appreciate it.

Another cloned of PowMr/MakeSkyBlue/EASun MPPT. You should use DC clamp-on meter to check the battery charging current, it will show lower value that what is shown on the display of this MPPT.
