A four-panel microinverter runs four panels from one unit, which cuts the number of inverters on a large array to a quarter and gives the lowest price per watt. Each unit is heavier and a single failure takes four panels offline, so they suit big, evenly lit arrays more than small roofs with patchy shade.
