The Victron VE.Direct Cable 1.8m (straight-both-ends version) is a genuine Victron Energy accessory that links two VE.Direct-enabled devices for data communication. Straight connectors at each end. Elevate also stocks a right-angle 1.8m version for tight enclosures — both variants appear in the size table below.
⚠ Do not: cut, splice, or join two VE.Direct cables together — it breaks the pinout and stops communication. If your devices are more than 10 metres apart, use a VE.Direct to USB interface with an active USB extension instead.
What VE.Direct is doing under the hood
VE.Direct is Victron's proprietary serial protocol — a simple bidirectional TTL data link running at 19,200 baud over four conductors. One Victron device talks to another, or a Victron device reports up to a GX product (Cerbo GX, Ekrano GX, GlobalLink 520) which then pushes data to the VRM cloud portal for remote monitoring. It's how a SmartSolar MPPT tells a SmartShunt how much solar is being harvested, and how any Victron device shows up on a phone or laptop through the VictronConnect and VRM apps.
The pinout is Victron-controlled and not published for third-party manufacture. A generic serial cable won't work, USB won't work, and no non-Victron VE.Direct cable is available. This is why the cable itself is a stocked item rather than something you build from bulk.
Common device pairings
Any two Victron devices with a VE.Direct port can pair, or one device can feed a GX product for cloud monitoring. The most common setups this cable ends up in:
- SmartSolar MPPT → SmartShunt / BMV battery monitor — MPPT reports charge current so the shunt's state-of-charge stays accurate on one screen.
- SmartSolar MPPT → Cerbo GX / Ekrano GX — sends solar production to the GX display and up to VRM.
- BMV-712 / SmartShunt → Cerbo GX — battery voltage, current, SOC and time-to-go into the whole-system dashboard.
- Orion Smart DC-DC → Cerbo GX — dual-battery charger reports charge stages and current back to the monitor.
- Any VE.Direct device → GlobalLink 520 — turns a single VE.Direct device into a 4G cloud-connected one without needing a full GX.
Which length do you need?
VE.Direct communication is supported over cable runs up to 10 metres total — pick the length (and connector) that matches how your devices are mounted. The yellow-highlighted row is what you're looking at now.
| Length | Connector | Typical use |
|---|---|---|
| 0.3m | Straight both ends | Ports mounted directly beside each other in the same port stack |
| 0.9m | Straight both ends | Two devices in the same enclosure, e.g. MPPT and GX side-by-side |
| 1.8m | Straight both ends | General reach across a small enclosure or panel |
| 1.8m | One end right-angle | Feeding into a tight enclosure or behind a panel where a straight plug won't clear |
| 3m | Straight both ends | Devices in the same compartment but not side by side |
| 5m | Straight both ends | Longer runs across a canopy, caravan, or boat cabin |
| 10m | Straight both ends | The longest run VE.Direct supports — devices at opposite ends of a large setup |
