AVERTISSEMENT : Risque d'électrochoc!
Il ne doit y avoir aucun mé lange entre les câbles de communication
et les lignes d'alimentation. Sé parez-les avec une distance aussi
grande que possible pour éviter un é lectrochoc.
There are two kinds of communication: RS-232 and RS-485. Please use
matching communication cables and make sure the cables are connected
firmly during data transmitting: the below features are supported with
communication interface:
Monitor each controller on the network using Solar Station PC software;
update the firmware.
RS-232, RS-485 Connection
The controller is a standard 3.81-4P port. Check Figure 1-1 for the port location.
The RS-232 port is 7
④ Power Wires Connection
 PV Wire Size
Since PV array output can vary due to the PV module size, connection method
or sunlight angle, the minimum wire size can be calculated by the I
array. Please refer to the value of I
modules connect in series, the I
PV modules connect in parallel, the I
The I of PV array must not exceed the maximum PV input current, please
SC
refer to the table as below:
Model
ET4415BND
ET6415BND
ET6420BND
NOTE: When the PV modules connect in series, the open circuit voltage of the
PV array must not exceed 138V (ET4415BND; ET6415BND) /180V
(ET6420BND) under the 25℃ condition.
