PID Recovery
Enabling/Disable the PID night recovery function. Once enabled, it
works between 22:00 pm and 5:00 am by default.
Clear PID alarm
If ISO impedance abnormality or PID function exception is de-
tected during running of the PID function, the inverter reports a
PID abnormity and reminds the user to take corresponding meas-
ures. Clear the alarm report via this parameter once the problems
are handled.
PID Scheme
Apply negative voltage when the inverter is connected to negative
voltage panel.
Apply positive voltage when the inverter is connected to positive
voltage panel.
After the PID night recovery function is enabled, the fault indicator on the inverter
front panel turns green.
