The Victron VE.Direct Cable is a proprietary point-to-point cable to connect two Victron devices with a VE.Direct port. It is also used for connecting a GX device, such as the Cerbo GX (the Cerbo has 3 VE.Direct ports), to another Victron product with a VE.Direct port, like a SmartSolar charge controller.
The VE.Direct Cable is available with straight connectors on both ends or with a 90-degree angled connector on one end and a straight connector on the other.
