Use of metre and CT sensors. In this case, both the current probes offered by ZCS and
other types of probes can be connected to the metre, which must be correctly set on the
metre.
The first method can be applied in all cases where the distance between the hybrid inverter and
the sensor insertion point is less than 50 meters. To extend the + and – cables of the CT sensor, it
is recommended to use 2 x 0.5mm
2
cables.
If the distance is greater, then the second method must be used.
The correct insertion point of the sensors or the Meter + CT sensors for measuring the currents
exchanged with the grid is shown in the figure below.
5.4.1.
Direct connection of CT sensors
In the case of direct connection of the CT sensors, use the dedicated connections supplied with the
inverter as shown in the figure.
These sensors must be connected directly to the CT input of the inverter shown in the figure,
according to the indications in the table.
