Two suggestions.
First - either in software setup or Hardware - setting up the ESP, where it talks about voltage divider
Fine tune vadjust value - test Voltage from panel using multimeter.
- using the serial monitor "vadjust ##" so the involt matches
- using the curl curl mppt.local --data "vadjust=##"
- don't forget save afterwards - so it gets picked up upon restart
Second - Hardware Build
Setting up the PSU
amend/update with instruction to enable "auto-output"
Keep pressing "SET" to enter parameter setting interface; press "Up" to adjust to "-F2-". Then press "OK" and it will display "Yo-0". Switch it to "Yo-1" by pressing "Up". Press "OK" to store the setting.
