1)
Correctly position the two current sensors (CT):
-
the CTa for measuring the energy exchanged with the grid must be positioned at the output of the
exchange meter (utility side) and must include all the phase cables entering or leaving the meter.
The CTa will therefore measure the energy taken from and fed into the grid by the photovoltaic
system.
-
The CTpv for measuring the photovoltaic production must be positioned on the phase cable exiting
the photovoltaic inverter (utility side) or from the production counter, and will only measure the
energy generated by the photovoltaic inverter.
2)
Extend the cable of the two sensors with a category 5 network cable (8 pole) using the caps supplied.
The cable can be extended by up to 100 metres with a minimum loss of signal

Below is a reference for connecting the sensors to the CT terminals supplied.
