Description
RCD refers to the residual current of the
SUN2000 to the ground. To ensure device
security and personal safety, RCD should
comply with the standard. If an AC switch with
a residual current detection function is installed
outside the SUN2000, this function should be
enabled to reduce the residual current generated
during SUN2000 running, thereby preventing
the AC switch from misoperations.
In some specific application scenarios, a power
grid company requires that the SUN2000 can
perform reactive power compensation at night to
ensure that the power factor of the local power
grid meets requirements.
This parameter is configurable only when
Isolation is set to Input ungrounded, with a
transformer.

When PID protection at night is set to
Enable, the SUN2000 will shut down
automatically if it detects abnormality of the
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 of the
PID voltage compensation during the
reactive power compensation at night.
If Power quality optimization mode is set to
Enable, the inverter output current harmonics
will be optimized.
