Studer VarioString VS-70
The VarioString responds to the toughest requirements in efficiency in solar installations. It also reduces the system costs by accepting PV strings up to 600 or 900Vdc. This allows for a more simple installation and reduces the installation time and material costs: reduction in cable cross-section and length, absence of junction box 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.

Studer Xcom-CAN Kommunikationsmodul
€305.00*
Studer Xcom-CAN Kommunikationsmodul
Multi-Protokoll-Kommunikations-Satz für Xtender- und Vario-Systeme
Dieses Tool ermöglicht die Kommunikation zwischen dem BMS, Lithium Batterie Management System, und den Produkten der Familie Xtender/VarioTrack/VarioString. Die Liste mit den zugelassenen Batterien (Hersteller) ist auf Anfrage bei Studer Innotec erhältlich.
Mit der Xcom-CAN ist es auch möglich mit anderen CAN-BUS Geräten (PC, programmierbarer Automat, Mikroprozessor) und allen Xtender/Vario Produkten über ein proprietäres Protokoll zu interagieren. Zum Beispiel kann ein System über ein SCADA gesteuert werden und bietet somit Zugriff auf Systemdaten, Parametereinstellungen und gespeicherte Logdaten.
Studer Xcom-232i Communication module
€315.00*
Studer Communication module Xcom-232i
The communication module Xcom-232i, equiped with a serial port RS-232, enables to be informed of the state of a system consisting of one or several Xtenders, VarioTracks or VarioStrings.
It is then possible to read all data that can be displayed on the remote control basic screen and also to modify the configuration parameters. An Xtender, VarioTrack or VarioString system can therefore be connected to various SCADA control and supervision devices (PC, programmable logic controller, microcontroller).
From a more technical point of view, the electrical interface RS-232 allows for instance the data transmission with GSM modems, RS-232 bridges to TCP/IP or also with long distance converters RS-422. Besides, in order to secure a total electrical separation between the Xtender, VarioTrack or VarioString system and the control and supervision device, the port is protected by means of a galvanic isolation.
The module Xcom-232i is also having a function of data recording and analyzing (Data logger function).
Studer Xcom-GSM
€620.00*
Studer Xcom-GSM Internet based communication sets
Xtender, VarioTrack and VarioString systems can now be constantly controlled from any remote terminal, computer, tablet or smartphone. The communication sets Xcom-GSM and Xcom-LAN allow connecting to sites with GSM mobile coverage or with internet-connection over a local network.
Studer Innotec provides this «plug-and-play» solution using a secure server and a simple and user-friendly interface.
The interface allows for remote interaction with the installation exactly as if on-site with the remote control RCC-02/-03, including: access to all parameters, real-time display of measured data of all devices included in the system and access to the last 30 days of log files.
Furthermore this solution makes it possible to consult the system’s event log at any time. It also allow users to configure alarm messages to be sent to one or more persons by e-mail or SMS. Any loss of internet connection can be indicated.
Xcom-LAN or Xcom-GSM?
Studer Innotec offers two different communication sets for providing access to the installation via internet. The available means of communication at the location of the installation will determine which set to choose.
If the installation has access to internet through a local area network (LAN), choose the Xcom-LAN set. If there is no available connection to the internet but access to a GPRS or 3G mobile network*, choose the Xcom-GSM set.
* the compatibility should always be verified with the mobile phone network operator
Studer BSP 500 Shunt

Throughput energy
Battery temperature
The BSP is offering a voltage measuring for 12, 24 and 48 V batteries and a current measuring by resistive shunt.
