Working Principle
A PID module is used in a PV array that comprises SUN2000s and is often installed in a smart array controller. In the scenario with a double-column transformer, the DC capacity of the PV array should be less than or equal to 10 MW. In the scenario with a dual-split transformer, the DC capacity of the PV array should be less than or equal to 16 MW.
