ArrayGuard®
Combiner Box
The heart of the intelligent combiner box is the CAN-bus-enabled
string current monitoring system, which monitors the string c­ urrents
at 100 millisecond intervals. The design of the ArrayGuard® adapts
to the actual plant topology. It connects up to 24 PV strings and
­offers fuse protection for the PV+ and PV- pole, depending on the
applicable earthing principle. DC load-break switch, overvoltage protector as well as their status monitoring are integrated. A dedicated
design and high quality finish to industry standards ensure a robust
control cabinet made of UV-resistant polyester designed for a long
service life in outdoor environments.

› string currents by highly precise and widely temperatureindependent shunt measurement (8 measurement channels)
› system voltage up to 1,500 V DC
› internal cabinet temperature
�Data transfer to local data logger via CAN fieldbus
�DC main cable with screw connection or cable lug
�
Integrated DC overvoltage protector with monitored status-­
signalling contact
�Integrated DC load-break switch:
› monitoring status-signalling contact
› disconnects ArrayGuard® from inverter under load
�Fuses on each single PV string

SYSTEM SOLUTION / PV PLANT MONITORING / skylog®
skylog®
Data Logger System
Our powerful data logging system for PV installations, skylog®, has
been designed with robustness and versatility in mind. Communicating
with the plant using any of the standard bus technologies (CAN,
RS-422, RS-485, Ethernet), skylog® can read and save data from
a variety of terminal devices, irrespective of make. Its i­ntegrated
uninterruptable power supply (UPS) provides power to all ­other
monitoring components supplied by the CAN bus cable, ­ensuring
­ ependable operation even in the event of a power f­ ailure. In locations
d
having unreliable internet connections, local data ­storage is secured
by skylog®’s substantial data buffering capacity. ­skylog® therefore
forms an indispensable component of any monitoring ­system where
dependable operation is key.

Power Plant Control
skycontrol is an integrated system for PV power plant control and
grid stability management. It meets grid operators’ requirements for
utility-scale PV installations to ensure controlled grid injection, both
at the medium and high voltage level, and can be flexibly adjusted
to comply with different regional, national and international grid
codes. An optionally included TeleControl Gateway complements
the skycontrol system in accordance with Transmission Protocols
IEC 60870, IEC 61850 and DNP3. Of course, the controller uses the
genuine closed-loop control principle, ensuring high-precision control
by measurement of all relevant physical quantities at the grid connection point and their continuous feedback to the controller input.
Combined with adaptable control algorithms and communication
sequences, this makes skycontrol a highly efficient tool for fast and
stable power plant control, even in large-scale and distributed PV
installations comprising several independent PV sections.

SYSTEM SOLUTION / POWER PLANT CONTROL / EnergyGuard
EnergyGuard
Energy Meter Gateway
Our energy meter monitoring device. At the grid connection point,
and downstream of the inverters, for instance, EnergyGuard integrates the energy meters into the plant communication in a way
that the output values can be recorded, displayed and analysed.
In this way, the interface evaluates the energy fed into the grid
and thus forms the basis for yield and performance ratio a
­ nalyses
which are subsequently visualized in the PVGuard® supervision
platform. In addition, our PVGuard® SCADA software transmits
the energy ­meter data to interested organizations and the energy
market authorities.
FUNCTIONS
�Available product types depend on the data transfer technology
to the PV monitoring system used:
› EnergyGuard CAN – data connection through CAN bus
› EnergyGuard ETH – data connection through Ethernet
�Energy data readout from energy meters via:
› RS-485 bus or
› impulse interface S0
FEATURES
�
Readout of several * energy meters which are identical in design
through a RS-485 interface
�Readout of one energy meter through two impulse interfaces S0

PVGuard® PRODUCTION FORECASTS
PVGuard® Production Forecasts provide you with reliable forecasts
about the expected power output of your PV plant at a defined time –
today, tomorrow, or in a few days.
An auto-adaptive algorithm creates forecasts of plant output on the
basis of the current weather data and the plant’s actual output over
recent weeks. Forecasts are updated multiple times per day and are
available to an hourly resolution up to 7 days in advance.
PVGuard® DATAPUSH
Main Features
› Hourly resolution up to 7 days in advance (up to 5.5 days in the
southern and 7 days in the northern hemisphere)
› High-quality weather forecasts from a leading agency
› Fully automated system modelling of the photovoltaic plant
› Continuous adjustment according to varying plant characteristics
8SOF00015
PVGuard® DataPush assembles the data, transforms it into standard
format, packs it into CSV files and delivers these by FTP push to the
customer’s remote FTP server. The plant data includes any measured
data channel across all devices and sensors in a plant, for example,
energy yield, power output, irradiance, performance ratio.
The data compilation can be customized
› Selection of data to be transferred
› Execution interval of data transmission
› Resolution of the data
› Aggregate functions for the data
PVGuard® COM
8SOF00022
8SOF00017
PVGuard® Com integrates the data of PV systems, which are not
equipped with data loggers from skytron® energy into the PVGuard®
Supervision Platform. The data from third-party data loggers is
automatically imported into the PVGuard®.
PVGuard® DataPush performs the following tasks
› The transfer of data to other software systems
(analysis and statistics)
› Automated production of reports outside the PVGuard® platform
(business intelligence)
› Data transfer to other SCADA systems
The data is provided in a standardized format (CSV) for further
processing and analysis.
PVGuard® COMBOX
1PGC00101
As an optional supplement for this import interface, the compact
data server PVGuard® ComBox actively fetches the plant information
stored on the plant’s data logger. Data retrieval from several data
loggers is enhanced by data concentration on the server, and by subsequent data conditioning, for efficient data transmission across the
Internet. The server’s web-based user interface allows configuration
of data transmission, network settings and administrative features.
