Multi plus 3000/120/50 has 3-8 v showing at + terminal

I have just installed a full Victron setup and lithium batteries,

When 12v power is turned on the voltage drops 3-8v, if I disconnect the + cables from the multi plus the system goes back to 12v, tried different cables on + & - from multi terminals to earth , no change.

Try charging the batteries? It looks like the battery protection system is operating to disconnect the load at low state of charge. Do you have communications set up for the system?
