...Swiss made Power VarioString VS-70 Reduce the installation costs of your solar system with the new MPPT solar charge controller, VarioString VS-70. The charge controller VS-70 offers an input PV voltage from 200 to 600V, totally isolated from the battery (48V), and supplies a charge current up to 70A. It enables an easy chaining of solar modules up to 4.2kW and provides many other features: Ÿ Ÿ Comprehensive display, programming and data logging features with RCC-02/-03 (opt.) Safe, simple and hassle free connection with PV connectors type SUNCLIXTM (Phoenix Contact “tool free”) Saving on cabling, fuses, combiner boxes and installation work in making only one string of PV modules Outstanding efficiency >98%, unrivalled for a isolated MPPT charge controller Fast and precise MPP algorithm (>99.8% efficiency) Losses in cables significantly reduced Full isolation between battery and PV generator giving total freedom in choosing either earthing system The VarioString VS-70 ensures a perfect charge of the battery and an charge efficiency higher than with AC coupled systems (via grid inverters) and for a lower cost while keeping all advantages of a high voltage PV string Connection to Studer CAN bus assuring a synchronized operation with all products of the Xtender family and an access to its communication accessories, settings and datalogger (RCC-02/-03, Xcom-LAN/GSM/SMS etc.) 2 auxiliary relays programmable with the accessory ARM-02 Command entry by dry contact for an external control of the function ON/OFF Fully programmable with the remote control RCC-02/-03 and/or the new communication accessory Xcom-SMS, or with internet-based communication tools Xcom-LAN and Xcom-GSM ...Simple, robust and performing… www.studer-innotec.com
