I am going to use two Zivan NG9+ http://www.zivan.it/en/overview.php?app=&id=ng9 3-phase 24V 200A battery chargers to build a custom UPS.
These devices have a CAN interface (they use it to communicate with each other in a master-slave relationship to allow parallel charging).
Could I connect these two loaders to a HAPCAN bus and then use the HAPCAN RS232 interface to communicate with the Zivans?
