I have a Multiplus 12/3000 connected to 600Ah LiFePO4 batteries. There is a CCGX connected to the VE.bus (lefthand port). The system is managed via a REC-A BMS via CAN bus connected to the CCGX..
After a loss of shore power, the Multi will not restart upon restoring the shore power until I unplug the VE.bus cable, and cycle the shore power breaker on the boat. Sometimes I also need to cycle the On/Off/Charge Only switch from On to Off and back to On before the Multi will restart.
None of the LED's on the Multi turns on when restoring the shore power (i.e. No "Mains On") until I unplug and cycle the power.
Once the system starts up, it operates normally with both the BMS and Multi seen on the GX.
The GX stays powered during this event, getting its power directly from the batteries. There is also a load (between 3-5 A) on the batteries at all times.
Any ideas?
