Description
Specifies the connection mode
of PV strings.

When the PV strings
connect to the inverter
separately (fully separate
connection), there is no need
to set this parameter. The
inverter can automatically
detect the connection mode
of the PV strings.

When the PV strings
connect to one another in
parallel outside the inverter
and then connect to the
inverter independently (fully
parallel connection), set this
parameter to All PV strings
connected.

When PID protection at
night is set to Enable, the
SUN2000 will shut down
automatically if it detects
abnormality in PID voltage
compensation during the
reactive power
compensation at night.
 When PID protection at
night is set to Disable, the
SUN2000 will operate in
grid-tied mode if it detects
abnormality in PID voltage
compensation during the
reactive power
compensation at night.
If this parameter is set to
Enable, the RS485-2 port can
be used. If the port is not used,
it is recommended that this
parameter be set to Disable to
reduce power consumption.
Specifies the operation mode of
the SUN2000 built-in PID.
Specifies whether to enable the
PID nighttime off-grid repair.
