4. Electrical Connections
4.1. Outlines of this chapter
This topic describes the SOFAR 3K~6KTLM-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 3K~6KTLM-G3,open-circuit voltage(Voc) of module arrays
connected in series must be≤550V.
Note
The connected PV modules must have an IEC 61730 Class A rating
