The below steps should be followed for connection:
1.
Lighting, short-circuit and other protection measures meeting the local electrical safety laws and regu-
lations are needed before proceeding to AC connection;
2.
Connect the output cables of the solar modules to the DC connector as shown in figure 13. Remove the
isolation layer of the DC cable for about 8-10 mm. Insert the conductor part into the connector at the
appropriate position, crimp the MC4 DC terminal and tighten the nut with a torque of 2.5-3 Nm. Ensure
the poles of solar modules are well connected with the connectors;
3.
After the DC connector is connected, use a multimeter to measure the voltage of the DC input string,
verify the polarity of the DC input cable, and ensure that the voltage of each string is within the allowa-
ble range of the inverter, as shown in picture 13B below.;
4. Connect the DC connector to the inverter and ensure it is tightly fastened.
5.
If you need to remove the connector from the inverter, you can help yourself by inserting a screwdriver
into the connector hole.
