I have 65A battery protect. It is installed on 24V circuit. The circuit voltage now is 26V and the protect gives an overvoltage status (E4) and disconnects the load; while the manual said the overvoltage threshold for 24V is 32V.
I need to reset the protect though programming to mode d. The unit shows A,B and C but never shows d. Any one have idea how to get mode"d" .
Best Regards
I found an answer somewhere here is the forum, it advices for the following for factory reset:
1- Disconnect the load.
2- Keep the program wire connected to the ground
3- Power the unit for 7 seconds, 3 segment should appear on the 7 segment (that doesn happen)
but after 7 seconds or more we disconnected the unit power and reconnected the whole system, the E4 bug has disappear.

Good day @MohammadL, I'm presuming that you have a regular BatteryProtect and not the Smart BatteryProtect?
**EDIT: Since my original answer, Victron software engineers have informed me (and I am updating here to record the information for future questions) that the missing "D" option is actually just an indication of an older-firmware BatteryProtect; the "D" (redetect system voltage) option was introduced in a later firmware iteration of the BatteryProtect. On earlier-firmware versions, system voltage detection can only be forced by disconnecting the BatteryProtect and then reconnecting it.
You've discovered that answer elsewhere on the Community since my original answer, but I wanted to update here as well so that there isn't conflicting information in answers. Cheers to the Community and to Victron for keeping an eye out and making sure the correct information is being distributed! /EDIT**
All that being said, it sounds like your particular application would be an excellent place for a Smart BatteryProtect, which allows you to fully customize your cutoff points to 1/100th of a volt rather than being limited to the presets of the regular BatteryProtect.
Dear @Justin Cook,
Thank you for your help
The LCD works fine while the unit is brand new. We tested it at office many times the d never shows up.
