yes.
But the limit seems independ from the inverter type. E.g., I use eight kostal html parser inverters and two modbus inverters. The system works. I now add an 11st inverter, and it breaks. This happens in any case, independently if the 11st inverter is a kostal htmlp parser type or a modbus type.
Thus it doesn’t look to me like a timing issue.
Technically there is no limits on the number of PV inverters. We run a system with 30+ pv inverters without any problems. Your inverter “Turnhalle 4” already indicates a problem as it doesn’t show a value. This may lead to subsequent faults. Without logs, it is hard to say what your problem is.
