CAN
The inverter is compatible with RV-C CAN, developed by the RVIA (Recreational Vehicle Industry Association).
CAN allows for the inverter to communicate with other units on the network.
For CAN to work properly, the inverter and all other units on the CAN network must be using the same CAN
protocol. If the protocols are different, the units will not recognize each other. The typical RV-C CAN network
is operated at 250 kbit/s, but the inverter may be configured for 500 kbits/s. Up to 13 inverter/chargers can be
placed on the CAN network. Each inverter/charger requires a unique instance to differentiate it from similar units.
If the inverter is connected to a network operating at a different Baud rate or a network that uses a proprietary
communications protocol, the inverter may not respond.
The inverter/charger supports most standard RV-C instructions in additional to several custom commands for
configuration changes. Contact the factory for more information. Reference document #131557 for further
descriptions of the included RV-C instructions.
