About MasterBus
All devices that are compatible with MasterBus are marked with the MasterBus symbol.
MasterBus is a CAN based, fully decentralized data network for communication between Mastervolt
devices. MasterBus is used as power management system for all connected equipment, such as the
inverter, battery charger, generator and many more.
Every device that is compatible with MasterBus is equipped with two data ports. The devices are
simply daisy chained together, forming a local data network. Monitoring panels such as the
SmartRemote or EasyView 5 can be used for monitoring and control of all connected MasterBus
equipment.
CAUTION!
Never connect a non-MasterBus device to the MasterBus network directly! This will void
warranty of all MasterBus devices connected.
How to set up a MasterBus network
- Connections between the devices are made by standard straight MasterBus cables. Mastervolt
can supply these cables.
- Up to 63 MasterBus devices can be interconnected.
- MasterBus needs a terminating device on both ends of the network.
- The electric power for the network comes from the connected devices according to the rule: 1
powering / 3 non-powering. Spread the powering devices over the network.
- Do not make ring networks.
- Do not make T-connections in the network.
