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.
