The best Victron products for van life are small, efficient and easy to monitor from a phone. A van electrical system has three charging sources (solar, the alternator and the occasional campground plug) and limited space and battery capacity. So low idle draw and compact size matter more than raw power. Here are our picks for each job, with the specs from Victron’s datasheets.
Best Victron Products for Van Life: Quick Picks
| Job | Pick | Key specs |
|---|---|---|
| Solar | SmartSolar MPPT 100/30 | 440W nominal PV at 12V, 100V max, Bluetooth |
| Alternator charging | Orion XS 12/12-50A | 50A, 98.5% efficient, 0.33kg, IP65 |
| Battery monitor | SmartShunt 500A | Under 1mA draw, Bluetooth, VE.Direct |
| Small inverter | Phoenix VE.Direct 12/1200 120V | 1,200W continuous, 11W zero-load, 1–3W ECO mode |
| Inverter + shore charging | MultiPlus-II 12/3000/120-50 | 2,400W, 120A charger |
| Shore charger only | Blue Smart IP22 12/30 | 30A, 0.5W no-load |
Solar: SmartSolar 100/30
Most van roofs fit 200–400W. The 100/30 suits about 440W on 12V; above that, step up to the 100/50 (700W). Both connect to VictronConnect for setup and harvest history.

Alternator: Orion XS
Driving is often your best charging source in winter. The Orion XS delivers up to 50A and lets you dial current down to protect a small alternator. It has engine shutdown detection, so it won’t drain the starter battery when you’re parked.
Battery Monitor: SmartShunt
Lithium voltage barely moves until the battery is nearly empty. A shunt shows the real state of charge.

Inverter: Phoenix or MultiPlus-II?
If you only need 120V for a laptop, a blender or camera batteries, the Phoenix VE.Direct 12/1200 is the efficient choice. If you plug into campgrounds often, a MultiPlus-II adds a 120A charger and a transfer switch, but it’s larger and draws 13W at zero load (3W in search mode).
Shore Charging Without an Inverter-Charger
The Blue Smart IP22 12/30 adds a 30A lithium-capable charger for occasional plug-ins.
See the Orion XS, Phoenix VE.Direct inverter and Blue Smart IP22 on Victron’s website.
Worked Example: A Weekend-Warrior Van
Light use, mostly weekends, with a 100Ah lithium battery:
- Solar: 200W of panels on a SmartSolar 75/15 or 100/20.
- Alternator: Orion XS 12/12-50A, dialled down to 30A if the alternator is small.
- Monitoring: SmartShunt 500A.
- AC: none, or a small Phoenix VE.Direct 12/375 for a laptop.
Daily use of about 600Wh (fridge, lights, fan, phone, laptop, estimate) is roughly half of a 100Ah lithium battery’s 1,280Wh. A sunny day on 200W and an hour’s drive at 30A put back most of it.
Worked Example: A Full-Time Remote-Work Van
Daily use of around 2,000Wh with a 12V fridge, Starlink Mini, a laptop and monitor, an induction cooktop used briefly and a diesel heater fan (estimate):
- Battery: 300–400Ah of lithium.
- Solar: 400–600W on a SmartSolar 100/50.
- Alternator: Orion XS 12/12-50A, or two in parallel if the alternator allows.
- AC: MultiPlus-II 12/3000 for the cooktop and shore charging.
- Monitoring: SmartShunt, plus a Cerbo GX and GX Touch for one dashboard.
With 500W of solar giving about 1,500–2,000Wh on a good summer day and a 2-hour drive adding roughly 1,200Wh at 50A, the system stays self-sufficient through most summer weeks (estimates).
Energy Budget Template
| Load | Watts (est.) | Hours/day | Wh/day (est.) |
|---|---|---|---|
| 12V compressor fridge (average) | 40W | 24 | 960 |
| LED lights | 15W | 5 | 75 |
| Roof fan | 20W | 8 | 160 |
| Laptop (USB-C or inverter) | 60W | 5 | 300 |
| Phone and accessories | 15W | 3 | 45 |
| Total | ≈ 1,540Wh |
Estimates; measure your own loads with the SmartShunt. Use your total to size the battery, about 1.5–2 days of use, and the solar: daily Wh ÷ peak sun hours ÷ 0.7. For 1,540Wh and 5 sun hours, that’s about 440W of panels.
A Simple Wiring Order for Van Builds
- Battery, main fuse and battery switch.
- SmartShunt on the battery negative, with every negative connection on its system side.
- DC distribution (busbars and fuse block) for 12V loads.
- Solar controller, then the Orion XS from the starter battery.
- Inverter or MultiPlus-II last, with its own fuse sized for its current.
Building in this order means each stage can be tested before the next is added.
Keeping It Compact
Mount the Orion XS, SmartSolar and SmartShunt on a single board near the battery to keep cables short. Leave space around each for airflow and for adding a Cerbo GX later. Victron’s products share VE.Smart Networking, so the MPPT and Orion XS can use the SmartShunt’s battery voltage and temperature for more accurate charging.
Winter and Cloudy-Weather Planning
Solar output drops sharply in winter, so the Orion XS often becomes the main charging source. A 50A unit adds roughly 600–700Wh per hour of driving (estimate), which can cover a day’s use in about two to three hours on the road. A Blue Smart IP22 or MultiPlus-II adds a fast top-up at campgrounds when you plug in. Keep lithium batteries inside the heated living space so they stay above their minimum charge temperature.
FAQ
Do I need a Cerbo GX in a van?
Often not. VictronConnect shows each device over Bluetooth. Add a Cerbo GX for one dashboard or remote access.
12V or 24V for a van?
12V suits most vans. Consider 24V once inverter loads approach 3,000W.
Is the Orion XS enough with a smart alternator?
Victron designed its engine detection with smart alternators in mind. You can also wire an ignition signal.
What size battery do I need for van life?
Most vans use 100–400Ah of 12V lithium. Add up your daily watt-hours and aim for one and a half to two days of use.
Can I add Victron products one at a time?
Yes. Many builders start with solar and a SmartShunt, then add an Orion XS and an inverter as their needs grow.
