Studer MPPT Charge Controllers VarioString

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.
