Protect PV.630 Operating Instructions

4 System Description

This chapter describes the operating modes and functions of the equipment.

4.1Operating Modes

Two different operating modes may be used:

∙Individual operation

∙Partner operation

4.1.1Individual Operation

In individual operation, the inverter works independently and is not connected to any other inverters. The DC infeed from the PV cells and the link to the AC mains are only connected to this inverter.

Switching operations, control commands and modifications to set- ting parameters are only performed by the unit concerned.

4.1.2Partner Operation

In partner operation, two inverters are connected via a CAN bus. The DC voltage infeeds of both units can be linked using a cou- pling breaker. Levels of efficiency can be increased in this operat- ing mode by running one inverter on two connected PV cells at less than full power. It is the inverter itself that connects and dis- connects the DC voltage; it is also responsible for switching the units on and off.

This operating mode is described in detail in Chapter 5.5.
