The only way to properly know, would be to know what software it run.Hi, unfortunately on the top right is a PWM controller (UC3845). The microcontroller has a serial bus and apparently an ISP interface for programming, but it seems hopeless to identify the microcontroller.
My PowMr M60-PRO works perfectly fine as long as it is in MPPT mode (Mode 4), but once it has switched to Mode 7, it does not return to MPPT mode, but rather lets the battery run down. I've tried all battery settings, all behave the same way. I think it's a software problem. I bought it directly from the manufacturer, but no response so far.
I expect PowMr to run older MakeSkyBlue firmware.
The old 60A unit is a copy of a very old makeskyblue unit, running v113 firmware.
The new PowMr 60A Pro seam to be a copy of newer makeskyblue, very similar internal to v119 version but I did not look at v117 internal. The makeskyblue v117 unit did had issue getting stuck at mode 7 so it's possible it's running that.
For what I know, you can upgrade it to v118. aliexpress.com/i/4000011273671.html
But I would not do that if you are not sure it is actually running makeskyblue v117 firmware as you can easily brick the device.
