New Li Battery Catamaran Install keeps shutting down

We recently replaced our AGM house batteries with 5 Smart Lithium 12V/200AH (V 1.20) or 1000AH. Added Smart BMS CL 12/100 (V1.06), SBP 12V/220A (V2.08, Bootloader V1.02), SmartShunt 1000A/50mv (V4.05), Cerbo GX (v 2.63)and have a Multiplus Compact 12/2000/80 (V unknown).

1. While sailing and using the electric winch the system reboots. Both motors on.

2. While sailing, motors on, the system rebooted Nav system, autopilot, VHF (12V electrical)

3. Sailing w/o motors -12v electrical quit. Had to restart our engines to restart the 12V system.

4. At the dock we started the generator and we lost the 12V electrical system. The 110/220V system works fine. At this point the 12V system has not returned.

We are working with our Victron Installer and local Victron Rep for the past month as items 1-3 have recurred but the solution has not been found. Any thoughts?

have you checked the status of the smart battery protect when the 12v cuts out? the app should show if the system was disabled by remote. Can you also take a screen shot of the battery protect screen from Victron Connect? Curious to see what Mode you have set. It should be C with the way your install is setup.
