Thank you folks for your support! What makes me a bit shaky is that in the first stage i only had one inverter. That configuration worked fine with the generator. Problem started when adding the second Axpert with a second set of modules. The source of the problem must be in the communication between the two Axperts. The generator is a Yanmar GBW10 diesel with an alternator MeccAlte ECP3, 7,7kW

My installation: 2 x 12 panels, 24 batteries à 1500Ah, Gel, 48v. 2 Axpert inverters 5kVA, configured as Master and Slave, running in parallel mode. 1 Generator à 7,2kVA 1 Victron Battery Monitor BMV700/2 No utility connection, stand-alone/island solution Expectation: Whenever batteries drop below 46,5v the Battery Monitor should start the generator to charge the batteries. Problem: The gen starts (manually to test) but does not get connected although the inverters recognize the generator input (wave icon). The technician says, that this is a design failure by the Axpert inverter. He has other clients with the same problem. He recommends to install a charger between generator and batteries. Does anybody have a similar installation that works? Or prove that this is indeed a design bug? If there is a design bug: Who should i contact? I live in Spain, Costa Blanca.
