1 INTRODUCTION
Congratulations! You are about to install and use a device from the VarioString range. You have
chosen high-tech equipment that will play a central role in the energy production of your solar
electrical installation. The VarioString has been designed to work as a solar battery charger; its
advanced and completely configurable functionalities will guarantee a perfect functioning of your
energy system.
When the VarioString is connected to batteries and photovoltaic panels, it automatically recharges
batteries in an optimum way with all the available solar power. The VarioString VS-120 can be
connected to two strings of PV modules in different configurations (series, parallel, or independent).
This configuration flexibility allows the user to optimise their installation. The accuracy of the Maximum
Power Point Tracking (MPPT) algorithm, the high output and low internal consumption ensure an
optimal valorisation of the energy produced by the PV modules.
The charge profile may be set freely according to the battery type or the operation mode. The
charging voltage is corrected depending on the temperature thanks to the optional external sensor
BTS-01.
The control, display and programming unit RCC-02/03 (optional) allows an optimal setup of the
system and guarantees the user a permanent control over all important parameters for the
installation with a clear display interface. Moreover, it allows recording the system data in order to
analyse later its functioning (data logging).
The parallel operation of several chargers is possible and offers modularity and flexibility enabling an
optimum dimensioning of your system according to your energy requirements.
The VarioString operates as an independent device but is also designed to be included into a Studer
energy system together with the Xtender inverters/chargers, the BSP battery monitor, the control,
display and programming unit RCC-02/03 and all Xcom communication modules. Working together,
these different devices have a synchronised behaviour for a better management of the battery and
of the solar resource.
Please read this manual carefully to ensure the perfect start up and operation of your system. It
contains all necessary information regarding the operation of the VarioString charger. The installation
of such a system requires special expertise and may only be carried out by qualified personnel
familiar with the local standards in force.
