Electrical Connections
Outlines of this chapter
This topic describes the inverter electrical connections. Read this part carefully before
connecting cables.
Step 4
Step 5
Step 6
NOTE:
Before performing electrical connections, ensure that the DC switch is OFF. Since the
stored electrical charge remains in a capacitor long 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 it exposed to sunlight and can create
an electrical shock hazard. Therefore, before connecting DC input power cable,
cover PV modules using opaque cloth.
Danger
The inverter has 2 MPP 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).
