...Swiss mind Power VarioString VS-120 Dual 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 Ÿ Reduces Balance of System costs (Eliminates expensive wiring for parallel strings, saving wires, connectors, junction boxes, fuses, space, time, etc) Ÿ Safe, simple and trouble free connection with SUNCLIX™ (Phoenix Contact “tool free”) PV connector Ÿ Fully protected against incorrect wiring Ÿ Simplified safety rules by full isolation between PV and battery and between MPPT inputs Ÿ Any grounding strategy applicable thanks to isolated Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Comprehensive display, programming and data logging features with RCC-02/-03 (opt.) MPPT inputs. Grounding system fault detection Fast, precise, best in class tracking algorithm brings MPPT efficiency >99% World champion for efficiency in isolated converter with >98 % conversion efficiency 7kW per unit and up to 15 units in parallel: 105kW Low self-consumption : < 1,2W in night mode 4 step charger fully programmable for longer battery life 9 LEDs to monitor status and current Optimal usage in an Xtender system with synchronized battery management Web access through Xcom-LAN or Xcom-GSM (opt.) SUNCLIX (Phoenix Contact“tool free”) 2 pairs supplied with unit ...Flexibility without compromise! Two independent MPPT inputs each with 200 - 600Voc (2 x 3.5kWp) Two MPPT inputs allow independent tracking of 2 different PV strings, Voc, and/or power, which brings optimized efficiency and greater flexibility for building integration. Two MPPT inputs in parallel each with 200 - 600Voc (2 x 3.5kWp) Parallel wiring allows simplified wiring with lower voltage when strings are same size, power and orientation. Two MPPT inputs in series with 400 - 900Voc (7kWp) Serial wiring allows the greatest flexibility and simplest wiring with any PV module on the market. 4K3C7
