Solar modules used with the

5�6�2 SOLAR PANEL ARRAY CONNECTION
Figure 17: Solar panel array connection�
Solar modules have always voltage at their connections, if exposed to sunlight.
Check that
PV switch
is off.
Before starting the procedure, be sure that the grid connection circuit
breaker is switched off�
Signal and ensure that there is no re-connection by accident�
Solar panel array connection to the
PV
input of the
CirPower Hyb
inverter is done by quick plug
MC4 connectors. These connectors are designed for this application, but it must be taken into
account that they are not designed for being unplugged under load conditions. There is a DC
switch to open the DC circuit before unplugging the MC4 connectors.
DC connectors are designed to handle a nominal current of
20 A
.
Do not connect a PV string with shortcircuit current higher than 20A.
Only connect PV strings to PV inputs.
In order to guarantee a proper crimping of the terminals, a specific tool from Mul-
tiContact must be used, and its instructions must be followed.
To connect the
CirPower Hyb
inverter to the solar panel array, follow these steps:
1�-
Check that the grid connection circuit breaker is switched off and signaled.
2�-
Check that the PV switch is off.
3�-
Check that the wire polarity of the solar panel conductors is Ok, and that the open circuit
