Quattro 10K 120V - No AC Load connected / Generator on / deep unbalance L1 vs L2 which charging the battery

The system is configured with two 10K Quattros 120V/240V Split phase with 4 SmartSolar Charge controllers, a Lithium Battery with a CAN-bus BMS and it also has a Lynx Ion Shunt. ESS is the only assistant configured in the Venus GX.

I am having a problem of unbalance L1 / L2 in ACin1(Generator). When there is no AC load connected, Grid is off, Generator is on, and battery is at 49% SOC the Quattros use correctly the generator to charge the battery, but it creates an unbalance situation, where L1 goes up to 3000W and L2 stays at 10W. This states is held for a few minutes until the Quattro give up and disconnects the ACin1(Generator) and stops charging.

So the only load in the system is the battery, for that the Quattro's need to rectify the electricity from the Generator, but it does it in an unbalance way. How can I tell the Quattros to pull the same or similar amount of power from L1 and L2 of the generator?

Thanks

Is your generator 120v or 240v?

Is your inverter arrangement trying to create 120v/240v splitphase?

Yes it is!

Yes the L1 and L2 voltage was stable at 120 to 122V.

Frequency was at 60.3Hz

ok, and what settings do you use for LOM detection?

did you measure the L1/L2 voltages when this happens? maybe the voltages are not stable?
