What Is a Microinverter?
Module-level power electronics explained — how a microinverter works and why it matters.
The basics
A microinverter is a small inverter mounted at each solar module that converts that panel’s DC output to grid-ready AC right on the roof. Instead of wiring panels in a long series string to one central inverter, every module gets its own conversion and its own maximum power point tracking (MPPT).
Why module-level matters
- Shade tolerance: one shaded or underperforming panel does not drag down the rest of the array.
- Per-panel monitoring: with a DTU gateway you see each module in S-Miles Cloud.
- Safety: module-level conversion enables native NEC 690.12 rapid shutdown.
- Design flexibility: mix roof orientations and add panels easily.
