Votronic Battery Charger VBCS 30/20/400 Triple HV CI 3270

Votronic Battery Charger VBCS 30/20/400 Triple HV CI 3270

The Votronic VBCS 30/20/400 Triple HV CI (MPN 3270) is your compact all-in-one control center for powering your motorhome: mains charger (20 A), VCC charger/B2B booster (30 A), and MPP solar controller (up to 400 Wp, max. module current 21 A) in one device. This means your batteries—whether connected to mains power (110–230 V AC), while driving, or via solar—are fully automatically charged using the appropriate charging profile for each situation. It also features a starter battery maintenance charger (4–5 A), Silent Run (night mode), power supply function, and CI-Bus preparation.

Three chargers in one—seamlessly integrated

Instead of combining three separate components, the VBCS Triple provides a fully coordinated solution. This saves space, simplifies installation, and ensures that charging priorities and profiles work together reliably in practice—whether you are parked at a campsite or on the road.

Mains charger (20 A)—usable worldwide

Thanks to its wide-range input of 110–230 V AC, the device can also be used flexibly while traveling. It reliably charges your leisure battery and includes a maintenance charger that keeps the starter battery charged with 4–5 A while the vehicle is stationary.

VCC charger / B2B booster (30 A)—powerful charging while driving

Modern alternators (e.g., in Euro 6 vehicles) do not always deliver "conventional" charging voltages. The integrated 30 A booster compensates for voltage fluctuations and line losses over long cable runs, ensuring that your leisure battery is charged effectively and cleanly even on shorter journeys.

MPP solar controller (up to 400 Wp)—get more from your solar panel

The integrated MPP solar controller (max. 400 Wp, 21 A module current) continuously searches for the optimal operating point of your solar panels. Conveniently, the AES output can control appliances when there is excess solar power—for example, automatically switching a suitable refrigerator from gas to 12 V operation (depending on the system).

Intelligent battery care—suitable for lead and lithium

You can set charging programs for gel, AGM, lead-acid, and LiFePO4 batteries. For lead batteries, an integrated battery trainer (pulser) can help counteract sulfation while the vehicle is stationary. The included temperature sensor adjusts the charging voltage to the battery temperature—this protects the battery, improves charging quality, and provides important protection for LiFePO4 batteries at low temperatures.

Your benefits at a glance

• Three charging functions in one device: mains charger (20 A), B2B booster (30 A), and MPP solar controller (up to 400 Wp)
• Fully automatic charging for each situation: mains power, driving, or solar
• Wide-range input of 110–230 V AC for flexible use while traveling
• Maintenance charger for keeping the starter battery charged (4–5 A)
• Efficient solar harvesting with MPP control (max. module current 21 A)
• Adjustable charging programs for gel, AGM, lead-acid, and LiFePO4
• Convenience and system features such as Silent Run (night mode), power supply function, and CI-Bus preparation

If you want a clean, space-saving charging setup for your motorhome that intelligently combines mains power, driving, and solar in one device while also reliably supporting lithium and lead batteries, the Votronic VBCS 30/20/400 Triple HV CI is an exceptionally well-thought-out solution.
