8.4.2 Without communication
Die Micro-Inverter-Versionen ohne Kommunikation sind
nicht für eine umfassende Überwachung bestimmt, und
können daher nicht durch Anwendung der AEconversion
Datalogger, Gateway oder Software verwendet werden. Um die
grundlegenden Daten der PV-Anlage überwachen zu können,
kann der Anwender einen unabhängigen Energie-Monitor
installieren.
9.0 Initial operation and registration with the utility company
During commissioning, the inverter must be supplied with PV
voltage. To start the inverter, it is also imperative that an AC
voltage is applied which is within the respective valid tolerance
range.
9.1 Anmeldung beim EVU
When registering and accepting the PV system, the modalities of
the respective utility grid operator must be observed.
Commissioning usually proceeds as follows:
•
Submission of the documents to the responsible utility
company
•
Installation of the system
•
Installation of the meter by the utility company
9.2 Acceptance of the plant by the utility company
The following documents are generally required for this:
•
Registration / completion notification by registered installer
•
Site plan showing the boundaries of the property and the
installation site of the PV system
•
General plan of the entire system with the equipment used
(single-pole representation)
•
Data sheet for self-generating systems
•
Description of the protective device with information on
type, circuit, make and function
•
Description of the inverter or
•
Declaration of conformity and clearance certificate
•
Information on the short-circuit resistance of the switching
devices
10.0 Switching off the inverter
You must switch off the inverter for adjustment, maintenance
and repair work. Proceed as follows:
•
Switch off the mains voltage (deactivate the external fuse
elements).
•
After switching off, check that there is no voltage
•
Follow the local regulations for work on electrical
installations.
- Danger to life due to electric shock at live
connections!
- Even after disconnecting the electrical
connections, life-threatening voltages are still
present in the inverter.
- Therefore, wait at least five minutes before
carrying out any further work on the inverter.
11.0 External limiting
The term „external limitation“ is understood to mean the remote
control of the output power of a PV system by the energy
supplier or the energy supply company (EVU).
According to the Renewable Energy Sources Act of 01.01.2012
(EEG, §6), external control of the output power must be possible.
Depending on the size of the system, 70% control can
also be used as an alternative.
This external power setting is carried out via ripple control
signals. For this purpose, a ripple control receiver must be
installed by the utility company.
The signals are then forwarded to the data logger. The data logger
has four potential-free contacts that are available for processing
the ripple control signals and are forwarded to the connected
inverters via the RS485 interface.
Further information can be found in the installation and operating
instructions of the data logger.
The power reduction is based on the maximum AC power
of the respective inverter in percent.
The energy suppliers have currently agreed on four percentage
values.
The power specifications and their influence on the inverters can
be seen in the following table.
