Victron quattro slow switch over when grid fails

I have a victron quattro 48/8000 which has slow switchover during loadshedding in south africa.By, slow I mean a delay of about 10seconds. The delay is experienced when solar mppts are active or during the day. When mppt are not active, nighttime the switchover is seemless

My setup

Ess configured without battery life

2 mppts 150/85

6 JA 545watt panels

1 pylontech UP5000

Quattro firmware version-500

Cerbo firmware version- 2.92

Mppt firmware 3.13

Any ideas on what the issues might?

Any guidance would be appreciated

What grid code are you running? Is the UPS function on?

I would have a look at the bms limits shown in vrm at those times. That is way too little battery for that inverter (50A cont iirc).

Perhaps also share the battery V/A charts, AC out and your settings for the charger, inverter and ESS cutoffs etc.
