Quattro inverter stuck in overload fault. Currently no load is present but inverter makes noise and goes into fault every time. Any way to reset? See photo

I’m also encountering this problem. I’ve found previous discussions on the old community site about upgrading firmware, but in this case that’s made no difference. Wondering if I missed something on the AC wiring side.
I took the unit to the dealer for service. I had a spare Quattro and installed it without any issue so the AC wiring was ok. Let’s see what the technician finds out. Thanks for your input.
Please do let us know the outcome. Have heard similar from another installer.
