Power Optimizer
A DC-to-DC converter installed behind each solar panel that maximizes the output of individual panels before sending power to a central string inverter.
Why It Matters
Power optimizers provide panel-level optimization (like microinverters) while keeping the cost closer to string inverter systems. They mitigate shading and mismatch losses.

Microinverter
A small inverter attached to each solar panel, allowing independent operation and optimization of each panel.
String Inverter
A central inverter that connects to multiple solar panels in series (strings). Less expensive than microinverters but less flexible.
Module-Level Power Electronics (MLPE)
A category of devices (microinverters and power optimizers) that manage power conversion or optimization at the individual panel level rather than at a central inverter.
