• Make sure the inverter is applied to an IT system before enabling the anti-PID
function.
• PID recovery and Q at night can be enabled at the same time, but can not work
at the same time. In the IT system, anti-PID and Q at night can work at the
same time.
• After PID recovery is enabled, it only works when the DC side of the inverter is
voltage-free.
• After the PID recovery function is enabled, the voltage of the PV string to
ground is 500Vdc by default.
• 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.
