120V 15A GFCI Shore Power Trips When Victron Quattro Is Running 240V Split-Phase

Setup:

  • Victron Quattro 48/5000 configured for 240V split-phase output
  • AC Input 1 connected to 120V 15A GFCI shore power outlet
  • System produces 240V output for loads (e.g., mini split)
  • Cerbo GX + VE.Bus setup, running fine otherwise
  • 3x100AH 48V Batteries for power assist
  • Victron MPPT Solar Charger Controller with (4) 460W Panels attached

Problem:
Every time I connect to a 120V 15A GFCI shore outlet, the breaker eventually trips only when running the 240V Pioneer minisplit.

What I’ve Tried:

  • Verified proper neutral-ground bond location (only at the Quattro)
  • VEConfigure: set low AC current limit (13.5A) Low as it goes
  • Enabled PowerAssist (Boost factor: 3.5)
  • No option visible in my assistant list to “Ignore AC Input L2 if 0V”
  • Using VEConfigure 3 (v90.04.240) with MK3-USB on Windows

The Mini Split can be running for hours without tripping and then sometimes only minutes before it trips.

What settings can I change or what would I have to do to make this function without tripping the GFCI?

I have attached the data around when this happens. You can see the spikes.
