What does it mean for a small solar inverter to 'ride through' a grid disturbance?

It stays on during small voltage or frequency disruptions.

  1. It shuts off at the first flicker
  2. It stays connected during small disruptions ✔
  3. It switches to nighttime mode

Why: Ride-through helps keep the grid stable. If the disturbance lasts long or is large, the inverter disconnects and shuts down.

Huh, didn't know that: Power frequency is an important indicator of grid health, per DOE.

The sun doesn't play hide and seek, it always comes out in the end.
