Sub-array controller
Smart sub-array controller is designed base on an outdoor cabinet. Data collector, RS485 signal SPD, PID module
and inductor, optical cable terminal box, PLC module, SPD, etc. can be installed in the cabinet to realize the
communication and control for sub-array of PV power station.

2.4.4 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.
l
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.
l
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.
PID repair function
When the inverter not running, the PID function module add reverse voltage for PV string to repair the
PV string which has occurred the PID effect.
