4.4.3 AC/DC disconnection switch
Fig. 4.2:
AC/DC disconnector
Intended purpose
By turning the AC/DC circuit breaker, the connections from the
inverter to the grid and the solar modules are disconnected or
closed. The disconnection of the connections is a basic prerequi-
site for safe working on the inverter.
Technical design
Rotary switch with two positions: OFFand ON
How does it work?
The inverter is disconnected from the grid (AC) and the solar
modules (DC) when the AC/DC disconnection switch is in posi-
tion OFF.

AC/DC isolating switches in the ON position
The inverter is connected to the grid (AC) and the solar modules
(DC) when the AC/DC disconnection switch is in position ON.

4.4.4 Power socket (AC)
Fig. 4.4:
AC socket
Intended purpose
The power supply socket is used to connect the inverter to the
grid to supply AC power to the grid
●
Feeding AC power into the public grid.
●
Providing power for the display from the grid when power is
not available from the solar modules.
Grid types that can be used
●
3-phase networks with neutral conductor: 3P4W (L1, L2,
L3, N, PE)
●
3-phase networks without neutral conductor: 3P3W (L1, L2,
L3, PE).
