Manufacturer Product Description:
The VarioString VS-70 allows connection of a PV string with a voltage range of 200 to 600 V, fully isolated from the 48 V battery, and can deliver a charging current of 70 A. This enables easy connection of a PV string of up to 4.2 kW.
Product Features and Performance:
Specialized tool thanks to the SUNCLIXT M PV connectors (Phoenix Contact “tool-free”)
Unmatched high efficiency >98%, better than any other isolated MPPT solar charge controller
Very fast and accurate MPPT search algorithm (>99.8%)
Savings on cables, fuses, junction boxes, and installation effort thanks to a single PV string
Significant reduction of cable losses
Complete galvanic isolation between PV and battery allows flexible grounding options on both module and battery sides
Parametrizable charging profile, optimized for your battery, achieves much higher overall efficiency at lower costs compared to AC-coupled inverter systems, while maintaining the benefits of high-voltage PV strings
Fully configurable and compatible with proven communication and data logging accessories: RCC-02/-03 (wired), Xcom-LAN/GSM (Internet), and the new Xcom-SMS
Optional AUX relay module ARM-02 allows adding 2 programmable switching contacts
Programmable control input via a contact
Dimensions (L/W/H) [mm]: 120 / 230 / 350
