We have dual Multiplus 12/3000 units wired in split phase to a Victron Autotransformer. The system is now faulting with error #24 when connected to shore power. This has been traced to the slave inverter. The back feed relay seems to be stuck closed. I would appreciate any available feedback. Thank you.
I have performed all the testing steps laid out in the error codes document: https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes">https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes
This occurs with no load on the inverters. Main breaker off.
We are connected to a 50 amp shore power plug working properly with other systems.
Step 1 video of error led's:
Step 2 disconnect input and output wiring:
Step 3 measure resistance:
Input and output neutrals - 95 ohms
Input and output line - 0 ohms
After reading all the other cases for error 24 on this community I have also done the following:
Removed inverter from split phase system, configured for stand alone.
Disconnected all AC wiring, power unit on - no issue
Disconnected AC input wiring only - no issue
Disconnected AC output wiring only - error 24 immediately present when shore power applied.
