Genuine Victron VE.Direct accessory
A genuine four-core Victron data cable for short, clean connections between compatible VE.Direct products and GX monitoring equipment.
The Victron VE.Direct Cable 0.9m, part ASS030530209, is the short-run communication cable used to link supported SmartShunts, BMV battery monitors, MPPT solar chargers, chargers, and VE.Direct inverters to compatible GX devices. At approximately 3 feet long, it keeps RV, marine, solar, and off-grid electrical boards organized without unnecessary coils of excess cable.
Carry battery, solar, charger, and inverter data to your GX system through the correct VE.Direct connection.
A connected Victron system depends on clean communication between each VE.Direct product and the central GX device. This genuine cable provides the exact factory-made link for supported devices, helping your Cerbo GX, Ekrano GX, or other compatible GX equipment receive the information used for monitoring, logging, and VRM visibility.
VE.Direct is its own four-pin communication standard. It is different from VE.Bus and VE.Can, which normally use RJ45 connectors, and it is not the direct CAN-BMS cable used by managed lithium batteries.
Connect compatible BMV battery monitors, SmartShunts, MPPT solar chargers, Orion XS units, Smart IP43 chargers, and supported VE.Direct inverters directly to an available VE.Direct port on a GX device. Always verify that both products have a VE.Direct port before ordering.
The 0.9-meter length is designed for components mounted on the same electrical backboard or inside one compact battery bay. It provides enough reach for neat routing without leaving large loops of unused data cable behind the equipment.

Common questions about VE.Direct compatibility, cable length, GX connections, battery communication, and installation.
VE.Direct uses a small four-pin connector for compatible battery monitors, SmartShunts, MPPT solar chargers, chargers, and supported inverters. VE.Bus and VE.Can normally use wider RJ45 connectors. MultiPlus and Quattro inverter/chargers use VE.Bus, while managed batteries and CAN-network equipment use VE.Can or BMS-Can. The cable types are not interchangeable.
No. Epoch batteries with native Victron communication use CAN-bus communication, not VE.Direct. The final battery-to-GX connection may require an Epoch-specific harness or a Victron Type A or Type B CAN-bus BMS cable, depending on the battery model and pinout. Follow the battery manual.
0.9 meters is approximately 2.95 feet. It is intended for short runs where the VE.Direct product and GX device are mounted on the same electrical backboard or inside the same compact battery compartment. Longer factory-made VE.Direct cables are available for devices mounted farther apart.
The standard straight cable has matching VE.Direct connectors on both ends and is not sold with a designated source or destination end. Align each keyed connector with the compatible VE.Direct port and insert it without forcing the plug.
Splicing or extending VE.Direct cables is not recommended. Use the correct factory-made length instead. Victron offers straight VE.Direct cables in several lengths up to 10 meters, and a VE.Direct-to-USB interface can be used where the GX installation requires additional USB-based routing.
Yes, provided the SmartShunt and Cerbo GX are within the 0.9-meter cable reach and an available VE.Direct port is present. Once connected, the GX device can display the battery parameters measured by the SmartShunt.
Yes, when the specific MPPT has a compatible VE.Direct port and the GX device has an available VE.Direct connection. Check the MPPT manual because some Victron products use VE.Can, and certain RS models have special connection requirements.
No. MultiPlus and Quattro inverter/chargers communicate through VE.Bus and normally require a straight-through RJ45 UTP cable for their VE.Bus connection. This four-pin VE.Direct cable will not fit the VE.Bus RJ45 ports.
No. This is a low-voltage data and communication cable. It is not designed to carry battery current, inverter output, solar-array current, or charger current.
Victron currently provides a standard five-year warranty program for its power-product range and accessories. Warranty handling normally goes through the original dealer, so retain the purchase record and exact part number.
