7.2. Create an inverter system
There are two options for creating an inverter system:
•
UsetheCreate System wizardviatheSystems > Add or Remove Systems menu,andselect
Create Inverter System fromthedropdownmenuofsystemstocreate.
•
Useaconfigurationfiletoimportaninvertersystem.
Afteraninvertersystemiscreated,itmusthaveoneT2Smoduleassignedtoit.TheT2Smoduleisa
