
Make sure the voltage of each PV array is less than 1500V at all times.
Permanent damage may occur otherwise.

Make sure the max. short-circuit current of the DC side is within the
permissible range. Permanent damage may occur otherwise.

SG125HV
String #1
String #N
The SG125HV/SG125HV-20 is a single stage inverter with only one
MPPT. To make full use of the DC input power and reduce the power
loss caused by mismatch, the type and rating of the PV modules
connected to one inverter should be the same, including:

the same PV module model;

the same number of PV modules;

the same angle of tilt of the PV modules;
6.3.2 PV Input Connection
During the PV string input connection, the DC current of each string
should be gathered together by a combiner box (or other combining
devices) and then connected to the inverter.
DC Cable Requirements
Select DC cables according to the following factors:
 The maximum operating temperature of the cable should no less than 90 °
C(+194 ° F).
