Introduction; General Information; About This User Manual - Studer VarioTrack VT-40 User Manual

1 INTRODUCTION

Congratulations! You are about to install and use an apparatus from the VarioTrack range. You have
chosen high-tech equipment that will play a central role in the energy production of your solar
electrical installation. The VarioTrack 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 VarioTrack is connected to batteries and photovoltaic panels, it automatically recharges
batteries in an optimum way with all the available solar power.
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 VarioTrack 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
configuration and display module RCC-02/-03 and the communication module Xcom-232i. 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 the necessary information regarding the operation of the VarioTrack 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.

2 GENERAL INFORMATION

2.1 A
BOUT THIS USER MANUAL
This manual contains all the necessary information and procedures to install, configure, use and
troubleshoot the VarioTrack charge regulators. It does not contain information about photovoltaic
modules (PV) or batteries of various brands that can be connected. For this kind of information,
please refer to the instructions of each specific manufacturer.
It covers the following models and accessories:
• Charger: VarioTrack VT-40, VT-65 and VT-80
• Temperature sensor: BTS-01
• Cooling fan: ECF-01
• External auxiliary relay module: ARM-02
Note: The VarioTrack solar charger has a different specification dependent upon whether it is
equipped with a cooling fan (model supplied under reference VT-80) or not (model supplied under
reference VT-65). It is also possible to add the ECF-01 cooling fan on a VT-65 model later
(see chap. 9.4). If the fan is added, the specification will become that of a VT-80. However, the
cooling fan ECF-01 cannot be added on a VT-40.
This manual is an integral part of the equipment and must be kept available for the operator
and/or the installer. It must remain near the installation so that it may be consulted at any
time.
