TL;DR
A power optimizer is a module-level DC-to-DC converter mounted under each solar panel that tracks that panel's maximum power point independently, so shade or soiling on one module no longer drags down the whole string feeding a central inverter. Optimizers also report per-panel production data and provide the module-level rapid shutdown the NEC requires.
What it means
A power optimizer is a module-level DC-to-DC converter mounted under each solar panel that tracks that panel's maximum power point independently, so shade or soiling on one module no longer drags down the whole string feeding a central inverter. Optimizers also report per-panel production data and provide the module-level rapid shutdown the NEC requires. SolarEdge systems pair them with a string inverter as an alternative to microinverters.
