If PV is connected to the DER port:
• Additional Production CT may need to be purchased to capture L1 lines of PV landing on both the IQ Combiner port and DER port in the
IQ System Controller 3M,
OR
• The existing Production CT in the IQ Combiner 5/5C, IQ Combiner 4/4C, or IQ Gateway can also be extended
into the IQ System Controller 3M and used to capture L1 lines of PV landing on the PV and the DER port.
NOTE: Revenue grade ANSI C12.20 Class 0.5 compliant metering accuracy is not supported when extending PV Production CT.
