Studer Variotrack VT 80-175 is the smart charge controller for maximum battery life.

The variotrack low voltage solar charge controllers ensure optimal energy harvesting from solar panels, delivering reliable charging for any 12, 24, or 48 V battery system. The accuracy of the MPPT algorithm, the high peak efficiency and low internal consumption ensure an optimal valorisation of the energy produced by the PV modules.

The vario chargers have been used in standard solar systems as well in special applications (hydro, DC/DC converters, DC minigrid).

100% offgrid/ongrid

• Low standby consumption (<1.2W) is perfect for an offgrid system.
• High MPPT tracking efficiency >99% and European weighted conversion efficiency >97%
• Directly compatible with our xtender series of inverter-chargers and our next series with the xcom 485i for offgrid/ongrid installations.

Flexibility

• Compatible with almost every battery technology with various charge management options.
• Fully programmable charging curve and PV algorithm, etc. With access to more than 300 settings.
• Multi-unit options up to 15 units with the xtender series of inverter-chargers (37.5kW) and 5 units with the next series (12.5kW). 

Designed for a wide range of uses

• Offgrid and backup application
• Solar autarky (self-sufficiency) with our next series of inverter-chargers
• Minigrids application
• On board power
• Mobile application
• Telecom application (48V DC systems or 230V AC with inverters)
• Hydro and Wind DC power
