Battery Equalizer

Article Index

The Vanner VANN-Guard Battery Equalizer is an efficient and highly reliable method of obtaining a 12 volt DC power source from a 24 volt DC electrical system. The VANN-Guard makes the batteries look like they are in series and parallel at the same time. In addition to providing regulated 12 volt power, the system ensures that battery voltages remain equal which significantly extends battery life.

Ideally suited for vehicle and alternate energy applications, the VANN-Guard is designed to save your batteries and the money you would spend replacing them. Users of the Vanner VANN-Guard know that it is the most cost effective and dependable solution for dual voltage systems. 


70 Series Stand-alone Equalizer

A typical 70 Series equalizer system would include a 24VDC power source, such as an alternator or solar array, two 12 volt battery banks in series, and the VANN-Guard. The VANN-Guard connects to the 24 volt, 12 volt and ground terminals of the battery system. When the 12 volt loads require power, the VANN-Guard ensures that the current is taken equally from both batteries, and that the voltages of the two batteries are kept equal. This equalization ensures extended battery life and provides a stable 12 volt supply for operating accessories.

Paralleling VANN-Guard: Models are available which provide 60, 80 and 100 amps of 12 volt DC power. VANN-Guard Battery Equalizers may also be operated in parallel to provide more power. For example, two 60 amp units can be installed to provide 120 amps of 12 volt DC power. 


80 Series Equalizer & Battery Monitor

A typical 80 Series equalizer system would include a 24VDC power source, such as an alternator or solar array, two 12 volt battery banks in series, and the VANN-Guard. The VANN-Guard connects to the 24 volt, 12 volt and ground terminals of the battery system. When the 12 volt loads require power, the VANN-Guard ensures that the current is taken equally from both batteries, and that the voltages of the two batteries are kept equal. This equalization ensures extended battery life and provides a stable 12 volt supply for operating accessories.

An additional CAN (Controller Area Network) Capable Smart Monitor is a device designed to monitor and report the status of several critical functions in the vehicle electrical system is provided. This unit provides real-time fault signals over the CAN bus to the vehicle electrical system controller. Fault indications can then be given from the vehicle’s electrical system controller.

90 Series Equalizer, Battery Monitor & Isolator

The Vanner VAN-Bus CAN Power Management System is an efficient and highly reliable method of maintaining isolation between your 24-Volt DC starting system and your 24-Volt DC auxiliary system. In addition to providing regulated 24-Volt power, the system provides charging to the 24-Volt auxiliary battery, when conditions permit, which significantly extends battery life. Ideally suited for vehicle and alternate energy applications, the VAN-Bus is designed to save your batteries and the money you would spend replacing them. Users of the Vanner VAN-Bus know that it is the most cost effective and dependable solution for 24-Volt systems.

The CAN (Controller Area Network) Capable Smart Monitor is a device designed to monitor and report the status of several critical functions in the vehicle electrical system. This unit provides real-time fault signals over the CAN bus to the vehicle electrical system controller. Fault indications can then be given from the vehicle’s electrical system controller. Battery-monitoring algorithms have been incorporated into the 90-60 Series VAN-Bus, transmitting real time battery state of charge, state of health, and run time messages over CAN.

A typical system would include a 24-Volt DC-starting system, a 24-Volt DC auxiliary system, and the 90-Series. The 90-Series connects to the 24-Volt starting system, 24-Volt auxiliary system and ground terminals of the battery system. When the auxiliary battery requires charging, the VAN-Bus ensures that the current is transferred from he starting batteries, when conditions permit, and that the auxiliary batteries can not drain the starting batteries when loads are left on. This isolation between the two 24-Volt systems ensures that the starting batteries will maintain the power required to start the vehicle, and provides a stable 24-Volt supply for operating accessories.
