Products from Votronic at a glance

At Offgridtec, you have a large selection of products from Votronic. For example, we carry high-quality charge boosters, battery computers or solar regulators that will convince you not only with their quality, but also with their price.

Votronic charge booster

The Charge Booster btw. Battery Charger from Votronic can be found in our Measuring and Display Devices category. These chargers ensure a fast and efficient charging process of the supply battery from the alternator while you are driving. They can be used universally and are particularly suitable for special vehicles, high-quality motorhomes and boats with galvanic insulation. The selectable charging programmes for classic lead-acid, lead-gel or AGM batteries enable monitoring-free, fast and gentle charging from any state of charge. Even during short journeys, the battery is charged with full current.

Votronic battery computer

The Votronic battery computer is supplied with a measuring shunt (precision resistor) which is used for precise measurement of direct and alternating current. At the push of a button, the battery computer provides comprehensive information about:

  • the current state of charge of the battery
  • the flowing battery currents and
  • the voltage of the battery

The values are given exactly to the percent (%) and the ampere-hour (Ah). The computer is suitable for all types of batteries: acid, gel, AGM and lithium-ion.

Votronic solar controller

The solar controllers from Votronic are the ideal solution for motorhomes or other applications with two different battery circuits, e.g. for the starter battery and the living area battery. These dual charge controllers can be adjusted to all major battery types and, in addition to excellent technical data, also have extensive accessories for optimum use. These controllers ensure that your mobile solar system functions reliably in the long term.

  1. What makes Votronic stand out? All Votronic products are state of the art and meet the highest quality standards "Made in Germany".
  2. What are the benefits of a battery computer? A battery computer is used to monitor the battery. It displays the current state of charge and the voltage of the battery. The battery computer receives its data via a measuring shunt which is installed on the supply battery.
  3. What are the benefits of a solar controller? A solar controller is an essential component of a photovoltaic system, because it is the controller that makes the direct current generated usable. It also serves as a transformer that specifically adjusts the voltage to the battery and the end devices.
  4. What are the benefits of a charge booster? A charge booster is placed between the starter battery and the body battery and permanently "fools" the alternator into thinking that the starter battery is not yet charged. In this way, a second battery can be charged while driving.
