Parameter Description
RCD enhancing 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.
Night-time reactive power
output
In some specic 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 congurable only when Isolation is set to
Input ungrounded, with a transformer.
PID protection at night ● When PID protection at night is set to Enable, the solar
inverter will shut down automatically if it detects
abnormality of the voltage compensation of the anti-PID
module during the reactive power compensation at night.
● When PID protection at night is set to Disable, the solar
inverter will operate in grid-tied mode if it detects
abnormality of the voltage compensation of the anti-PID
module during the reactive power compensation at night.
Power quality optimization
mode
If Power quality optimization mode is set to Enable, the
inverter output current harmonics will be optimized.
PV module type This parameter is used to set dierent types of PV modules
and the shutdown time of the concentration PV module. If the
concentration PV modules are shaded, the power drops
drastically to 0 and the solar inverter shuts down. The energy
yield would be aected since it takes too long for the power to
resume and solar inverter to restart. The parameter does not
need to be set for crystalline silicon and
lmy PV modules.
● When PV module type is set to Crystalline silicon or Film,
the solar inverter automatically detects the PV module
power when the PV module is shaded. If the power is
insucient, the solar inverter shuts down automatically.
● When concentration PV modules are used:
– When PV module type is set to CPV 1, the solar inverter
can quickly restart in 60 minutes if the input power of
PV modules drops drastically due to shading.
– When PV module type is set to CPV 2, the solar inverter
can quickly restart in 10 minutes if the input power of
PV modules drops drastically due to shading.
