Electrical connections
General information in this chapter
This chapter describes the electrical connections of the 3PH 10KTL-15KTL-V2 inverter. Carefully read this
section before connecting the cables.
NOTE:
Before making any electrical connections, ensure that the DC and AC circuit breakers are open.
Remember that the accumulated electrical charge remains in the inverter capacitor after the DC and AC
circuit breakers have been switched off. Therefore, it is necessary to wait at least 5 minutes to allow the
capacitor to discharge completely.
The inverter must be installed and serviced by professional technicians or
electricians.
Attention
The PV modules generate electricity when exposed to sunlight, which can pose a
risk of electric shock. Before connecting the DC input power cord, be sure to
disconnect the strings via the appropriate circuit breakers.
Danger
The maximum open-circuit voltage of the photovoltaic string must be less than
1000 V.
The 3PH 10KTL-15KTL-V2 has 2 two independent input channels (MPPT); all the
photovoltaic modules connected to them must be of the same model and brand,
and must be positioned with the same orientation (solar azimuth and inclination
angle).
Note
A.
Electrical connections
Describes the process for making the electrical connections.
B.
Connecting the PNGD cable (grounding)
Describes the connection of the ground cable (PGND) for the ground of the inverter.
C.
Connecting the DC input power cables
Describes the connection of the photovoltaic strings to the inverter using the DC power cables.
D.
Connecting the AC output power cables
Describes the connection of the inverter to the AC grid using the AC power cables (following the granting
of the grid connection by the distributor).
