DC-DC power optimizers decouple string current and voltage from the solar modules allowing each module to operate at its own maximum power point. DC bus voltage in series strings are set at conventional inverter’s most efficient operating point.Allows for a simpler and more efficient inverter design.

The SMART DC Boost Module isolates each panel in the string. If one panel is shaded or drops in output for any reason, it does not affect the balance of the panels in the string and the total string output is artificially maintained at 500 Volts DC while balancing current flow to the inverter resulting in a maximum AC output.
