Parameter Description
RS485-2 communication If this parameter is set to Enable, the RS485-2 port can be
used. If the port is not used, you are advised to set this
parameter to Disable to reduce power consumption.
Tracker controller Selects a controller vendor.
Duration for determining short-
time grid disconnection (ms)
The standards of certain countries and regions require that the
inverter should not disconnect from the power grid if the
power grid experiences a short-time failure. After the fault is
rectied, the inverter output power needs to be quickly
restored.
AFCI The North American standard requires that the inverter should
have DC arc detection function.

7.1.4.4 Built-in PID Recovery
Ensure that the inverter ground cable is securely connected. Otherwise, the built-in
PID repair function will be aected and electric shocks may occur.
Working Principle
When the SUN2000 is disconnected from the network, the built-in PID can repair
the PV– positive oset. (PV– positive oset refers to raising the voltage between
PV– and the ground to above 0 V through voltage compensation.) When designing
a PV plant,
conrm with the PV module manufacturer that the anti-PID voltage
compensation direction of the PV module is the PV– positive
oset. Otherwise, PV
modules may be damaged.
Procedure
Step 1 Choose Settings > Feature Parameters. The parameter setting screen is displayed.
