String #1
String #N
The SG125HV-30 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;
