Review on Intelligent USB Port Display PWM 50A Solar Charge Controller for 12V/24V Auto Charging Regulation by Andre Hawkins

A good quality device for its price. Since the documentation provided by the manufacturer is not sufficient, what is written can be improved. , it took me a few hours to figure out why my 325W 38+VDC panel wasn't powering my system's 24V battery. - The charge limit is specified in a programmable board parameter called "High Voltage Disable (HVD)", which is 30V. - As proof of my mistake, I installed a small panel and it works fine and charges the battery more slowly. - To fix things I have decided to buy an MPPT device to fill this need in my house and I will update it soon.
