4. Electrical Connections
Outlines of this chapter
This topic describes the SOFAR 1.1K~3.3KTL-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.
Attention
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
Danger
For SOFAR 1.1K~2.2KTL-G3,open-circuit voltage(Voc) of module
arrays connected in series must be ≤ 500V;For SOFAR
2.2K~3.3KTL-G3, it must be
≤
550V.
The power of PV grid-tied system which contain by several the
SOFAR1.1K~3.3KTL-G3 inverters must be < 3.68kw in Germany.
Note
The connected PV modules must have an IEC 61730 Class A ratin

NOTE:The DVC is the voltage of a circuit which occurs continuously between any two
live part in the worst-case rated operating condition when used as intended.
