Direction of power flow:
•
IMPORT → from grid to utility
•
EXPORT → from utility to grid
Phase shift between the voltage (V) and current (I)
expressed as a percentage → P/ (V x I) = cosϕ
Indicates the status of the current sensors:
•
UNFREEZE → direction not blocked (at each system start, the direction depends on the direction of the first current flow).
•
FREEZE → direction blocked (sensors keep the same direction at each start up).
After checking for the presence of a power flow towards the utility, freeze the CTs by pressing the arrow
so that the word
FREEZE appears at the bottom and then confirm with the fourth button
To unfreeze, press the third button to display the UNFREEZE message and then press the third key.
Confirm. By switching the system off and on in this way, the sensor can once again be directed.
