MASTERVOLT SOLAR SUNMASTER QS SERIES
MONITORING & CONTROL
QS Monitoring & Control
The intuitive approach: when you think it is possible,
it is. Part of the family of QS products is an extensive
program of communication, display and monitoring
facilities. The central philosophy is that you literally
should be able to play with the possibilities: when you
think a certain configuration is possible, it is possible
and easy to connect as well.
SUNMASTER QS SERIES
6
You are able to connect any type of device
in any arbitrary combination in a straight
forward way. From a simple local read-out
of a single inverter by PC to an extensive
system with multiple inverters, wireless
displays, data monitoring and remote con-
trol: both are easily designed, configured
and connected. Central to the concept is
the QS Data Bus with the QS Multi-Master
protocol, enabling bus wise connection of
all devices and automatic configuration of
all hardware and communication settings.
All options will become available in 2002.

1. QS Data Bus
The QS Data Bus is the heart of the com-
munication system of the Sunmaster QS
inverters. All devices are connected to this
bus in a straightforward way. Each device
has a bus in and bus out connection, with
RJ45 (standard telephone cable) connec-
tion. Physically the bus is a standard 8 pole
flat cable with a two way RS485 signal
path and auxiliary power supply.
data in several displaying modes; when a
QS Data Monitor is connected to the QS
Data Bus, the QS Link Wizard also shows
historical data in clear overviews. Data can
be exported in Excell or text format.
3. QS Communication Module
The QS Communication Module is used to
connect a Sunmaster QS inverter to the QS
Data Bus. It can be inserted easily in the
connection compartment of the inverter
and has three connections: two connections
for the QS Data Bus (bus in and bus out)
and one connection for the optional inte-
grated QS Display in the inverter.
4. QS Display
The QS Display is a display that can easily
be installed in the Sunmaster QS inverters
and enables the user to:
• Monitor the data from each inverter
connected to the QS Data Bus: solar and
grid voltage, current, frequency and
power, status, total energy and operating
hours and set points.
• Monitor total values of all inverters on
the QS Data Bus (total power, energy,
status).
• Adjust set points of the inverters connec-
ted to the QS Data Bus.
5. QS Data Monitor
The QS Data Monitor adds memory and
monitoring capacity to the bus.
It scans the QS Data Bus for available de-
vices and starts monitoring all data auto-
matically, storing 10 minute averages.
The most simple configuration is a point to
point configuration, leaving the bus in con-
nection of the first device and the bus out
connection of the second device unused.
The bus can be extended step by step, by
connection of a new cable and device to a
free bus in or out connection. The number
of devices connected to a single QS Data
Bus is standard 32, but can be extended to
a maximum of 256.
2. QS Link Wizard, the QS
System Management Package
The QS Link Wizard is a software packa-
ge, suited for the communication with one
or more QS inverters, or one or more loca-
tions, through several media. With the QS
Link Wizard you can directly communica-
te with a Sunmaster QS inverter to moni-
tor the data and configure its settings. Or
you can use it as a full monitoring and con-
trol package to control several PV plants at
different locations, with communication
connections through different media: di-
rect link, (GSM) modem connection or wi-
reless. The QS Link Wizard shows actual
