5.3 Connection to the PV Generator (DC)
CAUTION!
Unit Disconnection From Load
Disconnect the circuit breakers and switches of inverters AC and DC sides.
5.3.1 Conditions for the DC Connection
• The connected PV modules must meet following requirements
– Same type
– Same model
– Identical alignment
– Identical tilt
• The following limit values at the DC input of the inverter must not be exceeded (connecting to a higher
voltage will destroy the device):
Type Maximum input voltage [Vd.c] Maximum input current [Ad.c]
BNT050KTL
1000Vdc
36Adc*3
BNT060KTL
1000Vdc
40Adc*3
5.3.2 Assembling the DC Plug Connector
In order to connect to the inverter, all connection cables of the PV modules must be equipped with the DC
plug connectors provided. You will find the necessary DC plug connector for DC connection in the package.
To assemble the DC plug connectors, proceed as detailed below. Ensure the plug connectors have the
correct polarity.
The plug connector in DC side includes male and female as blow.
Please note that the sizes of metal connecting tubes are different. The bigger one is for female connector
and the smaller one is for male connector.
