3 Phase Quattro Overload Issue

I currently have a x15 Quattro48/10000 set up in a 3-phase configuration (5 units each phase). The system is off-grid and boosted by a 175 kW generator each evening for a few hours. Recently one Quattro on Phase 3 has been overloading during generator operation.


I have been able to temporarily remedy the problem by lowering the input current limit to 95A down from 110A. However, that 110A is what it has run at for the past 5 months without issue.

Previously the system has overloaded at generator startup/when the Victrons first accept the power, however these recent overloads have occurred hours into generator operation.

What could have the caused this Quattro to suddenly not be able to handle the incoming current?


Thank you

Also update all the Quattros to 481 and resolve the load imbalance issue
