A dual-panel microinverter runs two panels from one unit, each on its own input and tracker, so the panels still work independently while there are half as many inverters to mount and wire. They usually cost less per watt than single-panel units. Check the continuous output against twice your panel’s wattage and the per-input current against the panel’s current rating.
