Sungrow SG50CX User Manual

15
It is recommended to use the communication module from SUNGROW. Using a
device from other companies may lead to communication failure or other unex-
pected damage.
The inverter can provide export control but will require the use of a external smart meter.
The export control functionality has not been tested to AS/NZS 4777.2:2020.
Protection Function
The protective functions are integrated in the inverter, including anti-island protection, LVRT/
ZVRT, DC reversed polarity protection, AC short circuit protection, leakage current protec-
tion, DC overvoltage/overcurrent protection, etc.
PID recovery
The PID effect (Potential Induced Degradation) of PV modules will cause serious damage to
generated output and yield, which can be avoided or recovered by PID recovery function.
• For positive voltage scheme, after the PID is enabled, the voltage to ground of all PV
strings is greater than 0, and therefore the PV string-to-ground voltage is a positive value.
• For negative voltage scheme, after the PID is enabled, the voltage to ground of all PV
strings is lower than 0, and therefore the PV string-to-ground voltage is a negative value.
