This has been a common error on M190's for us. Is the string center fed, or fed from one end of the 17 inverter string? Where are the failed inverters on the string in relation to the transition cable(s)? Enphase has an App Note on voltage rise that might be relevant. They recommend center feeding long strings to avoid nuisance trips due to voltage range issues.
