Current Transformers (CTs)

CAUTION
Equipment damage. Only connect CTs provided by
Generac. Never connect to any other CTs. Connecting
to other CTs could result in equipment damage.
Current transformers (CTs) are required to use Self
Supply mode and to enable Import / Export Limiting
capability. CTs also allow the inverter to provide
information on utility consumption through the PWRcell
Inverter control panel and the PWRview monitoring app.
