This document describes how to rectify the Potential Induced Degradation (PID) in PV strings with P-type modules connected to Three Phase Inverters with Synergy Technology PN:SExxK-xxxxIxxxx

PID can also be mitigated by using a so-called “anti-PID box” that is installed between the strings and the inverter. The anti-PID box reverses the

To confirm PID you will need to test each panel separately with a PV mppt tester. If modules at the string ends are most affected then you have PID. If all modules are weak then you

The choice and configuration of inverters play a vital role in preventing or repairing PID. Here are three main strategies:

PID can also be mitigated by using a so-called “anti-PID box” that is installed between the strings and the inverter. The anti-PID box reverses the potential applied by the inverter in order to

A few methods can be used to help avoid PID in transformerless string inverters. Installers can add a grounded isolation transformer or ground the step-up transformer on the AC

The choice of glass, encapsulant used (in solar module) and the Anti-Reflective Coating (ARC) coating (on solar cell) are all found to affect and/or enhance the effect of PID.

Every PV string connected to a single- or a multi-MPPT inverter is subject to the PID effect, even though PV panel manufacturers protect their modules from this effect. The PID attacks the solar cell and
