Studer VT-40 VarioTrack Mppt Charge Controller 40 Ampere

Manufacturer's Product Description

VarioTrack Series

The VarioTrack solar charge controller meets the highest industry standards, is fully flexible and programmable, and therefore ensures optimal performance from the solar system.

When connected to solar panels and the battery, the VarioTrack automatically and optimally charges the batteries with all available solar energy using a sophisticated algorithm that quickly finds the Maximum Power Point (MPPT).

Maximum Power Point Tracking (MPPT) continuously searches for the optimal voltage from the solar generator to extract the maximum available power. This operating point constantly varies depending on conditions (sunlight, temperature) to which it adjusts (tracking).
