4. Electrical Connections
Outlines of this chapter
This topic describes the SOFAR 3K~6KTLM-G2 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
In Germany, the PV array maximum voltage must be
≤
600V, max
output of single inverter is 4.6KVA and max output of PV system is
13.8KVA.
SOFAR 3K~6KTLM-G2 has 2 MPPT trackers, all PV modules
connected to the same MPPT should have similar rated electrical
characteristics (including Isc, Voc, Im, Vm, Pm and temperature
coefficients), have the same number of series connected PV modules and
be all in the same orientation (azimuth and tilt angle).
Note
The connected PV modules must have an IEC 61730 Class A rating
