• Before enabling the anti-PID function or 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 the corresponding
user manual.
• If the voltage scheme for the anti-PID function or PID recovery function does
not meet the requirement of corresponding PV modules, the PID will not work
as expected or even damage the PV modules.
• When the PID recovery works (the indicator blinks blue once at long intervals
and three times at short intervals), disable the PID recovery function on iSolar-
Cloud App before manually powering on and maintaining the inverter.
