Designed to optimize overall value of 1,000 V large-scale photovoltaic systems, V1000 String Optimizers include String Stretch™ technology, which doubles number of modules per string, eliminating half of DC wiring and combining. Ampt Mode® technology increases inverter output power, lowering inverter and AC electrical cost per watt. In addition, 2 MPP trackers per PV string help optimize system performance.
