4.Electrical Connections
Outlines of this chapter
This topic describes the SOFAR 1~4KTL2-G3 inverter electrical
connections. Read this part carefully before connecting cables.
NOTE: Before performing electrical connections, ensure that the DC switch
is OFF. Since the stored electrical charge remains in a capacitor after the
DC switch is turned OFF. So it’s necessary to wait for at least 5 minutes for
the capacitor to be electrically discharged.
Installation and maintenance of inverter, must be operated
by professional electrical engineer.
PV modules generate electric energy when exposed to
sunlight and can create an electrical shock hazard.
Therefore, before connecting DC input power cable, cover
PV modules using opaque clot
For SOFAR 1~2.2KTL2-G3,open-circuit voltage(Voc) of
module arrays connected in series must be ≤ 500V; For
SOFAR 2.7K~4KTL2-G3, it must be ≤ 550V.
The connected PV modules must have an IEC 61730 Class A ratin
