Products Charge Controllers VarioTrack 80
  • Description

    The VT-80 is recommended for PV capacities up to 5kWp, and charges the battery with a maximum current of 80A.

    The battery management parameters can be adjusted on the inside of the device. On the outside, an LED display indicates the battery charge current and state of the VT-80.

    Given the specific system needs, several accessories can be added such as the Remote Control and Programming Centre RCC-02/03, a module with 2 auxiliary contacts ARM-02, a battery temperature sensor BTS-01, a battery status processor BSP-500/1200, or one of the communication sets Xcom-LAN/GSM/SMS.

    The VT-80 has a remote entry which provides the option to control the system from several parameters that can be programmed with the RCC-02/03.

    The combination of the VT-80 and Xtender series is the ideal solution for hybrid systems with several power sources such as solar PV, genset, etc.
