LED Error Codes

I am having a problem with the multiplus 2 when charging via shore power. It will randomly stop charging and show errors via the LEDs on front of the unit. However I can not figure out what one of the errors is trying to say.

The ‘inverter on’ is flashing in opposite to the ‘absorption’, and a solid ‘float’. (error 5)
It will flash twice before swapping to another error code:
The ‘inverter on’ is flashing in opposite to the ‘bulk’, ‘absorption’, and ‘float’. (error 13)

According to 6.3.2. VE.Bus error codes, the first error is 5 and the second is 13. I see that error 5 is overvoltage on AC-out but what is error 13?

Try the Victron Toolkit app, which decodes all possible LED blinking codes.

I have checked the app and it does not show that combination of LEDs. The only reason I was able to figure it out was because I saw it listed in the Error Indicators section of the manual.

Hi @TopHighway,

I have a theory that it is related to a communications issue, but I am asking internally to confirm.

Thank you for looking into it, I appreciate it! If it is any help I have changed out the RJ45 cable from the Multiplus 2 to the Cerbo GX three times and have had this issue with all three. They are official RJ45 cables ordered from Victron.
