Variotrack datasheet

Product catalog summary

Overview: The VarioTrack MPPT solar charge controller is designed to optimize energy generation by efficiently charging batteries. It features a precise Maximum Power Point Tracking (MPPT) algorithm, high peak efficiency, and low internal consumption, making it suitable for all battery technologies. Manufactured in Switzerland, it comes with a 10-year warranty.

Key Features:

Easy and safe commissioning with protection against incorrect wiring.
Rugged design for harsh environments (IP54 rated).
High tracking efficiency (>99%).
Supports up to 15 VarioTrack units in parallel on the same communication bus (75kW).
Four-stage charger for extended battery life.
Low self-consumption (<1W in night mode).
LED display for status and current monitoring.
Compatible with any solar and battery system, optimal in Xtender systems.

Accessories:

Remote control for display, programming, and data logging (RCC-02/-03).
Communication sets (Xcom-LAN/Xcom-GSM).
Battery temperature sensor (BTS-01) and Battery Status Processor (BSP).
Communication with lithium battery BMS (Xcom-CAN).
Additional auxiliary contacts (ARM-02).

Certifications & Warranty: The product is ISO certified (9001:2020/14001:2020) and includes a 10-year warranty (5+5).

Technical Specifications:

Maximum solar power recommended varies by battery voltage (e.g., 1250W for 12V, 2500W for 24V, 5000W for 48V).
Maximum solar open circuit voltage: 75V for 12V, 150V for 24V/48V systems.
Maximum output current: 80A.
Operating voltage range: 7 - 68V.
Four charging stages: Bulk, Absorption, Floating, Equalization.
Battery temperature compensation adjustable from -8 to 0 mV/°C.
Electronic protections include PV and battery reverse polarity, battery overvoltage, over temperature, and reverse current at night.
Operating temperature range: -20 to 55°C, with 100% humidity tolerance.
Dimensions and weight vary by model (e.g., VT-40: 3.8 kg, VT-80: 5.5 kg).
Conforms to Low Voltage Directive (LVD) 2014/35/EU and Electromagnetic Compliance (EMC) Directive 2014/30/EU.

Catalog excerpts

The variotrack MPPT solar charge controller maximizes the energy generated by charging the batteries in an optimal way. The accuracy of the Maximum Power Point Tracking (MPPT) algorithm, the high peak efficiency and low internal consumption ensure an optimal valorisation of the energy produced by the PV modules to all types of battery technology. The variotrack is 100% manufactured in Switzerland and has a 10-year warranty. 4K3I Call our specialists +41 27 205 60 80 or visit studer-innotec.com.
