  • Percent and amp-hour display
  • Bluetooth via VictronConnect
  • History and time-to-go data
  • SmartShunt has no display; a phone or tablet provides the display
  • LCD solar monitor shows output, current, voltage, charged capacity and solar energy
02

Victron Cerbo GX

Cerbo GX synchronises batteries, inverters and solar controllers, with local GX Touch access or remote monitoring through Victron services.

  • Wi-Fi, Ethernet and Bluetooth
  • Real-time energy flows
  • GX Touch 50 or 70 support
  • GX Touch connects by HDMI; remote access uses the VRM portal
  • Load prioritisation and grid feed depend on the installed system configuration
03

Boosters and mains chargers

Votronic 30/50/70 A boosters and Victron Orion-Tr Smart 30 A provide controlled charging, particularly with Euro 6 alternators.

  • Automatic engine-running detection
  • Lead and LiFePO4 profiles
  • Automatic parallel and buffer operation
  • Orion-Tr Smart is isolated, programmable and updateable by Bluetooth
  • B2B charging for Euro 6 alternators; no discharge while the engine is stopped
04

Votronic shore-power charging

Microprocessor-controlled charging keeps voltage, current and time within the selected profile and supports coordinated operation with solar, generator and alternator sources.

  • Storage and maintenance charging
  • Compensation for voltage loss in charging cables
  • Integrated electrical-system filtering
  • Charging profile matched to the installed battery

FREQUENTLY ASKED QUESTIONS

What to know before installation.

Do I need a charging booster?

For vehicles built from around 2015 and for lithium batteries, a matched DC-DC charger is usually advisable.

How fast does a booster charge?

Charging current is sized for the alternator, battery, cable route and travel profile.

Can booster, solar and charger run together?

Yes. Correctly planned, the sources complement each other.
