4.8 Connecting a PID Module

Context

The PID module is used to prevent PV module output power degradation due to the potential

induced degradation (PID) effect in a PV power system.

The SmartLogger can be connected to and manage only one PID module that supports the

Modbus-RTU protocol.

For the definition of the RS485 communications cable for the PID module, see the delivered

operation guide.

There are six RS485 ports in the SmartLogger. For the port descriptions, see Context in
