1. Studer 1883 Studer VarioString VS120
The VarioString meets the highest requirements to help solar systems achieve their best efficiency. It allows PV string voltages of up to 900V or 2 x 600V. The interconnection of PV modules into strings leads to considerable savings in system costs. The two independent, isolated MPPT inputs allow the connection of different PV strings with varying voltages, currents, and orientations, enabling a wider range of applications. Thanks to the galvanic isolation, all possible grounding systems of PV and battery are feasible.
Product features and performances:
- Easy installation, saving labor time, connection material, junction boxes, fuses, and cables.
- String voltages up to 900V or 2 x 600V.
- Optimal use with different PV fields (easy connection with SUNCLIX connectors).
- Full protection against wrong connections.
- PV grounding fault detection.
- Fast and precise MPPT algorithm allows power yield better than 99%.
- World's best efficiency for isolated controllers over 98%.
- 7kW per unit; up to 15 VarioString can be connected in parallel for a total of 105kW.
- Low self-consumption of less than 1.2W in night mode.
- 4-stage charger for longer battery life.
- Status and current display with 9 LEDs.
- Optimal use in an Xtender system with synchronized battery management.
- Internet access with Xcom-LAN or Xcom-GSM (optional).
- Comprehensive display, programming, and data logging with the RCC-02/-03 SUNCLIX (Phoenix Contact "tool free").
Dimensions: 133 x 322 x 466 mm
Weight: 7.5 kg.
2. Studer 1883 Studer VarioTrack VT-80
VarioTrack series
The VarioTrack solar charge controller meets the highest industry standards, is fully flexible and programmable, and thus achieves optimal performance from the solar installation. When connected to the solar panels and the battery, the VarioTrack automatically and optimally charges the batteries with all available solar energy thanks to a sophisticated algorithm that searches for the maximum power point tracking (MPPT). The maximum power point tracking continuously searches the solar generator for the optimal voltage to retrieve the maximum available power. This operating point varies constantly depending on the external conditions (solar radiation, temperature) to which it must adapt.
