Studer 1883 Studer VarioTrack VT-80

VarioTrack series

The VarioTrack solar charge controller meets the highest industry standards, is fully flexible and programmable, and thus achieves optimal performance from the solar installation. When connected to the solar panels and the battery, the VarioTrack automatically and optimally charges the batteries with all available solar energy thanks to a sophisticated algorithm that searches for the maximum power point tracking (MPPT). The maximum power point tracking continuously searches the solar generator for the optimal voltage to retrieve the maximum available power. This operating point varies constantly depending on the external conditions (solar radiation, temperature) to which it must adapt.
