Key Victron Components

We spec Victron Energy for every van build. Their components integrate over Bluetooth and VE.Direct, giving you full system visibility from one app.

⚑

MPPT Solar Charge Controller

SmartSolar 75/15 β€” 100/30

Bluetooth-enabled, auto-voltage detect (12V/24V). The 100/30 handles up to 400W of panels on a 12V system.

πŸ”Œ

Inverter / Charger

MultiPlus-II 12/3000

3000W continuous, 5500W peak. Built-in AC charger means shore power at a campsite tops up your batteries automatically.

πŸš—

DC-DC Alternator Charger

Orion-Tr Smart 12/12-30A

Isolates your van battery from the starter battery. Charges at up to 30A while driving β€” critical for lithium on smart alternators.

πŸ“Š

Battery Monitor

SmartShunt 500A

Tracks state of charge, current, voltage, and power in/out. Pairs with the Victron Connect app over Bluetooth.

πŸ“‘

System Hub + Remote Monitoring

Cerbo GX + VRM Portal

Ties all Victron components together. Monitor and control your entire system remotely from your phone, anywhere in the world.

πŸ”‹

LiFePO4 Batteries

100–300Ah, 12V

We recommend quality LiFePO4 cells (Battle Born, Epoch, or Victron Smart batteries) paired with Victron monitoring. 2000+ cycles, no memory effect.

Size Your System

Don’t guess your power needs β€” run the numbers first. Start with the load audit, then battery sizing, then solar.

Van Build Pro Tips

Lessons from dozens of van builds β€” the things that save you from expensive mistakes later.

πŸš— Always Use a DC-DC Charger

Modern vans with smart alternators (Ford Transit, Mercedes Sprinter) won’t properly charge a lithium battery without a DC-DC isolator like the Victron Orion-Tr Smart. A simple split-charge relay isn’t enough.

β˜€οΈ Slim Panels on High-Profile Vans

For Sprinter and Transit high-roofs, use low-profile flexible or semi-flexible panels to stay within height limits. 100W slim panels can be tiled efficiently across most van roofs.

πŸ”‹ Oversize Your Battery Bank

Most van builders wish they’d started with more storage. If you’re planning 100Ah, go 200Ah. LiFePO4 can be discharged to 80% DOD, so usable capacity is less than the nameplate spec.

⚑ Right-Size Your Inverter

A MultiPlus-II 12/3000 handles almost any van load. Don’t oversize to 5000W unless you have 400Ah+ of battery β€” a large inverter will pull down your batteries fast at peak draw.

πŸ“ Fuse Everything Near the Battery

Every positive cable leaving the battery needs a fuse or breaker within 18 inches of the terminal. For the main cable to your inverter, use a Class T or ANL fuse sized to the cable β€” not the inverter draw.

πŸ“‘ Install VRM From Day One

The Victron Cerbo GX + VRM portal lets you check your system state remotely, spot issues before they become problems, and is invaluable if anything goes wrong while traveling.
