2.1 WHAT IS MASTERBUS? 
 
All devices that are suitable for 
MasterBus are marked by the MasterBus 
symbol. 
 
MasterBus is a fully decentralized data network for 
communication between the different Mastervolt 
system devices. It is a CAN-bus based 
communication network which has proven itself as a 
reliable bus-system in automotive applications. 
MasterBus is used as power management system 
for all connected devices, such as the inverter, 
battery charger, generator and many more. This 
gives the possibility for communication between the 
connected devices, for instance to start the 
generator when the batteries are low. 
 
MasterBus reduces complexity of electrical systems 
by using UTP patch cables. All system components 
are simply chained together. Therefore each device 
is equipped with two MasterBus data ports. When 
two or more devices are connected to each other 
through these data ports, they form a local data 
network, called the MasterBus. The results are a 
reduction of material costs as only a few electrical 
cables are needed and less installation time. 
 
For central monitoring and control of the connected 
devices Mastervolt offers a wide range of panels 
which show full status information of your electrical 
system at a glance and a push of a button. Four 
different panels are available, from the small 
Mastervision compatible 120 x 65mm LCD screen 
up to the full colour MasterView System panel. All 
monitoring panels can be used for monitoring, 
control and configuration of all connected MasterBus 
equipment. 
 
New devices can be added to the existing network in 
a very easy way by just extending the network. This 
gives the MasterBus network a high degree of 
flexibility for extended system configuration, not only 
today, but in the future as well! 
Mastervolt also offers several interfaces, making 
even non-MasterBus devices suitable to operate in 
the MasterBus network 
For direct communication between the MasterBus 
network and a product which is not from Mastervolt, 
the Modbus interface is recommended. 
 
CAUTION: Never connect a non-
MasterBus device to the MasterBus 
network directly! This will void warranty of 
all MasterBus devices connected.
