The inverters are each connected to the following pins:
1 (RS485A +) and 3 (RS485B -) to 2 (RS485A +) and 4 (RS485A -)
When doing so, make sure to always wire from pins 1 and 3 to 2 and 4, starting from the master inverter.
Please note that commissioning ("Basic settings") must only be carried out on the MASTER inverter.
Under "Basic settings" -> "Device management", the cascaded inverters can be added using the "plus symbol".
Commissioning ("Basic settings") must NOT be carried out on the SLAVE inverters. Otherwise the system would assume that the SLAVE is a MASTER.
If individual parameters are to be changed on a SLAVE, this can be done later via the FusionSolar Monitoring Portal.
Or on site by connecting to the APP on the inverter under "Settings", "Power adjustment", ... - but NOT in the "Basic settings"
ATTENTION:
When using a Smartlogger3000, all devices can be put into operation together.
