Many thanks for your reply: - we do not have storage device installed - Is the meter compulsory only to set the two inverter in cascade? We never had this condition using for i.e. Fronius or Kostal inverters setting in master and slave. - Smart dongle is connected correctly at the moment to the master inverter In case meter is a condition to operate in cascade, we may connect both inverters with it's dongle installed on each inverter and check them separately in fusion solar

Ok thanks, may you tell me then what are we doing wrong with these PV System with 2 SUN2000 10KTL in cascade? We are able to see only one inverter in fusionsolar and the dongle, the second one (slave) has no dongle installed and is connected via RS485 to the master one. During the setup fusionsolar recognized both inverter and the dongle. I don't figure out what could be the issue. Thanks.

Check whether the communication addresses between the inverters (the two inverters must be unique) and the RS485 cable connections are correct. In cascading scenarios, you need to manually search for cascaded inverters. https://support.huawei.com/enterprise/en/doc/EDOC1100165056?section=o002
