The Victron VE.Direct Cable 3m (ASS030530230) is the essential communication link between Victron Energy devices in your solar power system — enabling real-time data exchange at up to 19,200 baud over a dedicated asynchronous serial interface. The cable uses a 4-pin JST-PH connector at each end and carries both data and a low-current power feed, allowing connected devices such as the VE.Direct to USB interface or VE.Direct Bluetooth Smart dongle to draw power directly from the port without a separate supply. At 3 metres in length, it offers the reach needed to route cleanly through cabinetry, bulkheads, or battery compartments without daisy-chaining extensions. Designed specifically for use with the full range of Victron MPPT solar charge controllers, BMV battery monitors, Phoenix inverters, and other VE.Direct-equipped devices, this cable is the go-to solution for Australian caravanners, motorhome owners, and 4WD tourers building or expanding an off-grid power system. Whether you're connecting a BlueSolar or SmartSolar MPPT to a Cerbo GX for fleet monitoring, linking a BMV-712 battery monitor to a VE.Direct Bluetooth dongle for smartphone visibility, or integrating a Phoenix inverter into a managed energy system, the 3m cable gives you the flexibility to mount components where they make sense — not just where the cable reaches. Built to Victron's rigorous engineering standards, it's the reliable backbone of a professional-grade 12V, 24V, or 48V off-grid setup suited to Australia's harsh outback and coastal environments.
