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 power supply in your motorhome: Mains charger (20 A), VCC charge converter/B2B booster (30 A) and MPP solar controller (up to 400 Wp, module current max. 21 A) in one device. This ensures that your batteries – depending on the situation, whether on shore power (110–230 V AC), while driving, or via solar – are charged fully automatically with the appropriate characteristic curve. Additionally, it offers features such as a secondary charging branch for the starter battery (4–5 A), Silent Run (night mode), power supply function, and CI-Bus preparation.

Three chargers in one – neatly integrated

Instead of combining three individual components, with the VBCS Triple you get a coordinated solution. This saves space, simplifies installation, and ensures that charging priorities and characteristic curves work together reliably in practice – whether you're 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 be used flexibly even when traveling. It reliably charges your leisure battery and has a secondary charging branch that supplies or maintains the starter battery with 4–5 A while stationary.

VCC Charge Converter / B2B Booster (30 A) – powerful charging while driving

Modern alternators (e.g., Euro 6 vehicles) do not always provide "classic" charging voltages. The integrated 30 A booster compensates for voltage fluctuations and line losses over long cable runs, ensuring that your leisure battery is noticeably and cleanly recharged even on shorter trips.

MPP Solar Controller (up to 400 Wp) – get more from your module

The integrated MPP solar controller (max. 400 Wp, 21 A module current) continuously searches for the optimal operating point of your solar modules. Practical: The AES output can control consumers when there is a solar surplus – e.g., to automatically switch a suitable refrigerator from gas to 12 V operation (system-dependent).

Intelligent Battery Care – suitable for lead-acid and lithium

You can set charging programs for gel, AGM, lead-acid, and LiFePO4 batteries. For lead-acid batteries, a battery trainer (pulser) is integrated, which can counteract sulfation during idle periods. The included temperature sensor adjusts the charging voltage to the battery temperature – this protects the battery, improves charging quality, and provides an important safety aspect for LiFePO4 at low temperatures.

Your Advantages 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 depending on the situation: shore power, driving, or solar
• Wide-range input 110–230 V AC for flexible use when traveling
• Secondary charging branch for maintaining the starter battery (4–5 A)
• Efficient solar harvesting through MPP control (module current max. 21 A)
• Adjustable charging programs for gel, AGM, lead-acid, and LiFePO4
• Comfort and system features such as Silent Run (night mode), power supply function, and CI-Bus preparation

If you want a clean, space-saving charging infrastructure for your motorhome that intelligently combines shore power, driving, and solar in one device and reliably supports both lithium and lead-acid batteries, the Votronic VBCS 30/20/400 Triple HV CI is a very well-thought-out solution.
