Description

Fully configurable and developed to meet the highest industry standards, the MPPT solar charge controller VarioTrack ensures maximal efficiency in retrieving energy from any PV system.
When connected to solar panels and batteries, the solar charge controller VarioTrack automatically charges the batteries in an optimal way with all the available solar power using its algorithm for Maximum Power Point Tracking (MPPT).
The MPPT continuously seeks out the solar generator’s optimal voltage to retrieve the maximum available energy. This operating point varies constantly depending on outdoor conditions (sunlight, temperature…) to which it must adapt.

The VarioString responds to the toughest requirements in efficiency of solar installations. It also reduces the system costs by accepting PV strings up to 600 or 900VDC. This allows for a simpler installation, reduces material costs by the reduction in cable cross-section and length, the absence of junction boxes and string fuses.

The two isolated MPPT inputs allow for the integration of PV strings with different electrical characteristics and orientations. The reinforced isolation between the PV modules and the battery allows for any combination of grounding schemes and an optimised system security.
