Correctly position the current sensor:
•
CT (measure the current exchanged with the grid)

Positioned at the output of the import/export meter so that all incoming
and outgoing power flows can be read, it must include all the phase cables
entering or leaving the meter.

The direction of the CT is independent of the installation, and is
recognised by the system during the first start-up.
Replace the cover and secure it with the four screws; then
tighten the cable glands.
Unscrew the 4 screws of the central cover with a
screwdriver
Remove the waterproof cover (B), loosen the cable gland
(C), and then remove the stopper.
Route the CT cable through the cable glands on the right
side of the cover, connect the positive and negative
cables of the sensor to the counterpart contained in the
inverter kit, then insert the counterpart into the
corresponding port on the inverter board.

For the extension cable, it is recommended to use a category five 8-pole mains
cable, or a 2x0.5 mm² cable. In the first case, four conductors will be connected to
one pole of the sensor and the other four will be connected to the other pole.
To prevent the conductor wires from breaking, it is recommended to use a cable
with flexible and non-rigid conductors.
