AC Limit and powerassist not working - kick out the fuse

Motorhome
2x Multiplus 2 3000/48/35 in parallel
220V
Power Assistant enabled Ratio set to 1.0 (and 2.0) for test
No Cerbo or VenusOS
Limit to 7,4A in maain screen of Victron connect
Limit to 3,7A on each of both units
Charger limit to 10A ob 48V
2x BMS boxes and each 16 cells LifePo
External local fuse 10A

If no power on AC Out is consumed, all works fine, limit the charging current.
Turn on the electric cooking field and set to max - breaker is cut the power


Usually the power assist should be go not over the 7,4 from external and limit the charging current, but its still not working. It always cut the power as it goes over the 10A form AC in and not using the batteries.

Do i miss any setting here?

Make sure the rocker switches on the multi's are in the 'ON' position and not 'Charger'

Confirm you have one shared battery bank. Not one battery on each inverter?

Second in inverting only can you run the cooker?

If it does and you tong test, does the system current share correctly from the central bank?

Of is does not the the system is not balanced. This will translate to the power assist function and the input problem.

Have you tired without the power assist off. (Unchecked)?
