2.5 Particular Dangers associated with Photovoltaic Systems
Here you will find information about the additional dangers associ­ated with photovoltaic systems.
An active power source is connected. Depending on the operating status, the PV cells and the equipment may be live.
Crystalline silicon cells Crystalline PV cells (silicon cells) usually have an IT system
configuration, i.e. a non-earthed system that will be inadvertently earthed in the event of an earth fault.
A generator with a complex branched structure can only be shut down with a great deal of difficulty (in the event of a short circuit, for example).
DANGER
Contact with voltage! Extremely high DC voltages of up to 1000 VDC are present.
Risk to life due to electric shock.
Do not touch live parts. Wear personal protective equipment ( Chapter
2.2.3).
Thin-film cells To prevent corrosion, thin-film cells must be earthed.
Lightning protection
The desired level of protection can only be achieved if a lightning protection zone concept has been implemented for the building where the unit is to be installed, in accordance with DIN VDE 0185-4.

3.7 Technology
Protect PV.630 Operating Instructions
Due to the utilisation of high-performance electronic components, the equipment boasts a very high degree of operational reliability, is extremely efficient and is characterised by its versatility in com­municating with other systems by means of interfaces.
The entire control electronics system for the equipment is based on the use of microcomputer assemblies. The fact that the various assemblies are logically integrated and linked into the overall sys­tem means that unit properties can be defined by making unit­specific parameter settings in the software.
Information is exchanged between the individual modules using the CAN bus (Controller Area Network). This CAN bus features high interference immunity and is used in a wide variety of indus­trial applications.
The figure below illustrates the principle of the equipment.

The main assemblies of the inverter are:
DC load interrupter switch Q4 Inverter stack, display and control unit with communication
components
AC filter Inverter output contactor K7 Mains transformer (external) Mains disconnector Q26 (external)
The PV cells supply the inverter stack with DC voltage via DC load interrupter switch Q4. The inverter stack converts this DC voltage into a 3-phase AC voltage. A sinusoidal current is fed into the mains via the AC filter, inverter output contactor K7 and the mains transformer.
DANGER
Risk to life due to electric shock.
Mains disconnector Q26 (external) and the isolator in the genera­tor connection box (GCB) are there to isolate the inverter in the event of unit faults or when maintenance needs to be performed on the unit.
The control unit is supplied with power from the AC mains or, op­tionally, from a second AC mains.

4 System Description
This chapter describes the operating modes and functions of the equipment.
4.1 Operating Modes
Two different operating modes may be used:
Individual operation Partner operation
4.1.1 Individual 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 set­ting parameters are only performed by the unit concerned.
4.1.2 Partner Operation
In partner operation, two inverters are connected via a CAN bus. The DC voltage infeeds of both units can be linked using a cou­pling breaker. Levels of efficiency can be increased in this operat­ing mode by running one inverter on two connected PV cells at less than full power. It is the inverter itself that connects and dis­connects 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.

5 System Function
5.1 Description of Sequence Control
As soon as the equipment's control module is supplied with volt­age, sequence control starts.
Initially, load interrupter switch Q4 remains open. Once the initiali­sation phase is complete and if no deactivating faults are pending, load interrupter switch Q4 is closed. During subsequent operation, the switch is only opened by deactivating faults ( Chapter 6).
Inverter output contactor K7 remains open initially. The contactor is switched by the sequence control.
The figure below provides a graphical illustration of the sequence control statuses.

The equipment has been switched off logically via the DOU or the master control unit.
The equipment is running without faults, the monitoring systems are not activated.
In this status, no power is fed into the mains. Possible change of status:
The status can be switched from “OFF” to “Waiting for feed condi­tions” by switching the equipment on via the DOU and the master control unit.
5.1.2 The “Waiting for Feed Conditions” Status
The values of the DC voltage on the PV cells, the mains voltage and the mains frequency are monitored by the equipment.
