Note c: When the SUN2000 is disconnected from the grid and stops working,
the built-in PID can achieve the PV– positive offset of the PV module. (PV–
positive offset refers to raising the voltage between PV– and the ground to
above 0 V through voltage compensation.) When designing a power plant,
confirm with the PV module manufacturer that the anti-PID voltage
compensation direction of the PV module is the same as the direction of the
PV– positive offset. Otherwise, PV modules may be damaged.
For the SUN2000 that supports built-in PID repair, when Built-in PID running
mode is set to Repair, there is repair voltage between PV modules and the ground
at night. If you need to maintain PV modules at night, power off the SUN2000 to
avoid electric shocks.
