When set to 0, the inverter automatically detects the CTs number and
direction of CTs.
•
A value of 1 assumes a specific orientation and direction of CTs.
CTTurnsRatio •
Turns ratio of the CTs installed.
•
Default turns ratio of 1500 is compatible with included clamp type CT's
•
If installation restriction requires larger accessory CT's, set point shall be

CTs when turned ON.
•
Once CTs are detected and calibrated, a utility pole
symbol will appear on the lower right corner of the
home screen power flow diagram.
•
If manual CT calibration
CalOverride to 1. The CalOverride setpoint is
accessible through the Mod. Settings menu via the
inverter device page. See
information.
– CT1 must be connected to Line 1.
– CT2 must be connected to Line 2.
– CT3 must be connected to line 3 (for three phase
applications).
– All CTs must be pointed such that positive cur-
