The Variostring high-voltage MPPT solar charge controller ensures optimal battery charging while maximising solar production. The first of its kind, the Variostring achieves the world’s highest conversion efficiency from high-voltage solar (900 V) to 48 V battery voltage, including galvanic isolation between PV and battery. The Variostring is 100% designed and made in Switzerland and comes with a 10-year warranty.
World champion in efficiency for an isolated converter, with efficiency >98%.
Safety guaranteed thanks to reinforced isolation between the PV generator and the battery, allowing independent earthing of the battery and/or solar panels.
Reduces balance-of-system costs (eliminates expensive wiring of parallel strings).
Safe, simple and effortless connection with the SUNCLIX™(Phoenix Contact “tool-free”) PV connector.
Fully programmable 4-stage charger to extend battery life
