User Manual
Before enabling the PID recovery function, make sure the voltage polarity of
•
the PV modules to ground meets requirement. If there are any questions,
contact the PV module manufacturer or read its corresponding user manual.
If the voltage scheme for the PID recovery function does not meet the
•
requirement of corresponding PV modules, the PID function will not work as
expected or even damage the PV modules.
When the inverter is not running, the PID module will apply inverse voltage to PV
modules, to restore the degraded modules.
If the PID recovery function is enabled, it only works at night.
•
After the PID recovery function is enabled, the voltage of the PV string to
•
ground is 500Vdc by default, and the default value can be modified
through the App.
