CHARGE CONTROLLER SOLAR MPPT STUDER

CHARGE CONTROLLER SOLAR MPPT VARIOSTRING VS-70

The VarioString VS-70 is a MPPT 70A solar charge controller. It is recommended for PV capacities up to 4.2kWp, and charges the battery with a maximum current
of 70A. The solar modules are connected in series to form one single string (up to 600V) connected to the VS-70, all this without special tools and with reusable connectors

CHARGE CONTROLLER SOLAR MPPT VARIOSTRING VS-120

The VarioString VS-120 is a MPPT 120A/48V solar charge controller. Fully isolated dual MPPT inputs up to 600V (Voc) (2×3.5kWp) or up to 900V (Voc) (7kWp) with MPPT inputs in series.
