MPPT Solar Charge Controller Dual USB Solar Controller Smart LCD Screen MPPT Tracking 5V/2A Dual

On the charger spec says it works up to 50volt solar panel input . No way !! It overheat in seconds and don’t regulate the output voltage . Can’t access the settings as the instruction leaflet manual supplied . Don’t work . Only can change to view readings but can’t . It’s Only made to work on max 30 volt solar power input as tested .

The parcel was delivered to the house by Nova Poshta. Thank you. The controller is powered by a solar panel and shows everything correctly. Thank you. ---I had to change my review. Immediately the controller worked correctly, but after a couple of days it started to malfunction. I checked everything until I took the same one from a neighbor and it works stably, but mine started to drop the voltage at the input and output and raise the current strongly. I am an energy engineer with 36 years of experience. The voltage at the output rises from 9 to 16 volts, and the current is from 1 to 16 amperes, and it puts (SHORTS) the solar panels away. The video shows how when the panels are turned on, the voltage drops and the current jumps from 06 to 6.4. ampere continues to blink, this is when the batteries are charged, and when they are discharged, it blinks even more, and thus does not allow the inverter to work. ---Thank you, 50% of the money for the defect in the controller was returned on 09/23/24.
