The StecaGrid DualString range consists of a solar grid connected inverter, a solar grid-tie inverter, a PV grid inverter and a solar inverter. This range is built with a four-line display, a data logger used to store yield values and a country-specific grid that monitors changing current outputs. An interface card may also be included. Each inverter is equipped with two inputs that are installed with an MPP tracker. A single module string can be linked to each input and if needed, the inputs can be linked in a parallel way. This system provides low susceptibility to negative effects such as semi shadowing, functional faults or the dropout of a string.
