3 phase generator not charging battery properly

I have a 3 phase Victron system (3 x Quottro 8kVa), with a Freedom Won 30kWh battery


I have integrated a 30kVa 3 phase generator (Generator on AC Input 1 and Grid on AC Input 2)


When Grid is lost and battery goes down to 40%, the generator starts automatically, but it is not being accepted by the inverters, and it keeps on trying, but fails, probably because of high loads


I have made a test, and with all other loads off, the generator kicks in, but only ONE inverter charges the battery, at 3000 watts, the other 2 inverterss only kick on briefly, for just about 10 seconds, then they stop charging


The generator is 30 kVa , so it has 10kVa per phase


On VE configure, AC 1 Input current limit is 35 amps (for generator)

On the "Charger" tab, max charge current is 60 amps


Are there any changes that need to be made?

Confirm you have the same settings on all three inverters?

Have you checked the weak ac option? If available for your grid code.
