Voltima VBS25 Charge Booster with integrated Solar Charge Controller 25A

Description

The DC battery chargers of the VBS series are one of the most effective ways to charge the vehicle's 12V main or auxiliary battery via the alternator, or alternatively through a 24V or 12V starter battery, or optionally using solar power. They are compatible with a variety of alternator types and provide correct charging voltages for AGM, gel, deep-cycle batteries, and even LiFePO4 batteries. When the vehicle is stopped or upon arrival at the destination, solar charging automatically starts through the solar panels on the vehicle's roof.

Compactly designed and easy to install; IP66 rated, resistant to dust, water, shocks, and extreme temperatures ranging from -20°C to 80°C, allowing for use in motorhomes, commercial vehicles, boats, yachts, and many other applications. The charging boosters are fanless and silent, have a compact size, and are equipped with a three-stage charger and multiple electronic protection devices.

Features:

• 25A Solar MPPT
• 25A Charging Booster
• Input from solar and alternator
• Efficiency up to 95%
• Excellent performance in harsh environments
• IP66, resistant to dust, water, and shocks
• Compatible with Euro6 alternators
• Safety precautions such as undervoltage, overvoltage, overtemperature, and reverse polarity

Charging process in three steps:
Step 1: Maximum current until the target value of constant voltage charging is reached
Step 2: Current decreases, constant voltage charging mode starts
Step 3: Stop of constant voltage charging at the corresponding battery voltage and initiation of maintenance charging

Installation of the Voltima charging booster:
A button is used to select the battery technology: lithium or lead-acid/AGM/gell. The Battery Booster has a connection for the Voltima VBS remote control. A monitor informs the user about the current battery charging status, among other things (not included, available separately, see accessories). Additional connections, such as for a voltage measuring cable or temperature sensor, are also available.
