Remote control connection
The connection and disconnection of the inverter to and from the grid can
be controlled through an external control.
The function must be enabled in the specic menu. If the remote control
function is disabled, the switching on of the inverter is dictated by the pres-
ence of the normal parameters that allow the inverter to connect to the grid.
If the remote control function is operating, besides being dictated by the
presence of the normal parameters that allow the inverter to connect to the
grid, start-up of the inverter also depends on the state of the terminal R+
compared to the terminal R- present on the connector
13
.
When the R+ signal is brought to the same potential as the R- signal
(that is to say when a short-circuit is created between the two connector
terminals), the inverter is disconnected from the grid.
The remote control OFF condition is shown on the display.
Connections for this command are made between input “R+” e “R-”.
Since this is a digital input, there are no requirements to be observed as
regards cable cross-section (it only needs to comply with the sizing re-
quirement for passing cables through the cable glands and the terminal
connector).
Connection enabling Stand-alone output
If the stand alone accessory board is installed on the inverter, it is able
to convert the voltage from the photovoltaic generator even if there is no
grid voltage (off grid operation).
In the event of an extended black-out, it is possible to manually enable
the stand alone output to which a secondary emergency circuit can be
connected.
Enabling the output is carried out by setting the +SA signal to the same
potential as the -SA signal (i.e. creating a short-circuit between the two
connector terminals).
Once the electrical power supply has been restored, the inverter will
automatically disable the stand alone output returning to normal oper-
ation (connected to the electricity grid); in subsequent black-outs, it will
once again be necessary to enable operation of the accessory board.
