2.4.5 PID Function (Optional)
If PID function is configured and enabled, the voltage of all PV string to ground is greater than zero,
that is to say, the voltage of all PV string to ground is positive voltage status.
Before enable PID protection or repair function, please pay attention to the polarity requirement
for the voltage of different PV string to ground. If any question, please contact the manufacturer
of PV string or read the user manual of PV string.
When the type of PV string mismatch the voltage scheme of PID protection or repair function,
the PID function will not reach the expected effect even cause harmful influence for PV string.
