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 motorhomes: mains charger (20 A), VCC charging converter/B2B booster (30 A), and MPPT solar controller (up to 400 Wp, module current max. 21 A) in one device. This ensures your batteries are charged fully automatically with the appropriate characteristic curve – depending on the situation, whether from shore power (110–230 V AC), while driving, or via solar. Additionally, it offers features such as a secondary charging circuit 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, the VBCS Triple offers you a coordinated solution. This saves space, simplifies installation, and ensures that charging priorities and characteristic curves work together reliably in practice – whether you're at a campsite or on the road.
Mains Charger (20 A) – Usable Worldwide
With 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 features a secondary charging circuit that supplies or maintains the starter battery with 4–5 A during downtime.
VCC Charging 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 your leisure battery is noticeably and properly recharged even on shorter trips.
MPPT Solar Controller (up to 400 Wp) – Get More from Your Module
The integrated MPPT solar controller (max. 400 Wp, 21 A module current) continuously searches for the optimal operating point of your solar modules. Practical feature: The AES output can control consumers when there is a solar surplus – for example, to automatically switch a suitable refrigerator from gas to 12 V operation (system-dependent).
Intelligent Battery Care – Suitable for Lead and Lithium
You can set charging programs for Gel, AGM, Lead-Acid, and LiFePO4 batteries. For lead batteries, a battery trainer (pulser) is integrated, which can counteract sulfation during downtime. 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 Advantages at a Glance
- Three charging functions in one device: Mains charger (20 A), B2B booster (30 A), and MPPT 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 circuit for maintaining the starter battery (4–5 A)
- Efficient solar harvesting through MPPT control (module current max. 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 infrastructure for your motorhome that intelligently combines shore power, driving, and solar in one device and reliably supports both lithium and lead batteries, the Votronic VBCS 30/20/400 Triple HV CI is a very well thought-out solution.
