VarioString VS-70 and VS-120

VS-70

The VarioString VS-70 is a MPPT 70A solar charge controller. It is recommended for PV capacities up to 4.2kWp, and charges the battery with a maximum current of 70A. The solar modules are connected in series to form one single string (up to 600V) connected to the VS-70, all this without special tools and with reusable connectors.

 

VS-120

The VarioString VS-120 is a MPPT solar charge controller 120A/48V. Fully isolated dual MPPT inputs up to 600V (Voc) (2x3.5kWp) or up to 900V (Voc) (7kWp) with MPPT inputs in series. 

 

• Reduces Balance of System costs: eliminates expensive wiring for parallel strings, saving wires, connectors, junction boxes, fuses, space, time etc

• Safe, simple and trouble free connection: with SUNCLIX™ (Phoenix Contact “tool free”) PV connector

• Fully protected against wrong wiring

• Simplified safety rules by full isolation between PV and battery and between MPPT inputs

• Any grounding strategy applicable thanks to isolated MPPT inputs. Grounding system fault detection

• MPPT efficiency >99%: fast precise best in class tracking algorithm. World champion for efficiency in isolated converter with >98% conversion efficiency

• 7 kWp per unit an up to 15 units in parallel: 105 kWp

• Low self-consumption: < 1,2W in night moode

• 4 step charger fully programmable for longer battery life

• 9 LEDs to monitor status and current

• Optimal usage in a Xcom-LAN or Xcom-GSM

• Certifications: EMC 2004/108/CE – LV 2006/95/CE – RoHs 2002/95/CE – IEC/EN 62109-1:2010 – IEC/EN 61000-6- 3:11 - IEC/EN 61000-6-12005
