MINV · POWER CONVERSION
Off-Grid Microinverter
A microinverter that converts the direct current from a solar panel into alternating current usable directly in systems with no grid connection. Because each panel gets its own module, a failure in one panel or module leaves the others unaffected and performance differences between panels do not propagate through the system. An MPPT algorithm adapted to partial shading tracks the maximum power available from the panel.
