# Grid Fault

> Grid voltage/frequency alarms — separating a weak grid from a weak connection, the compliant way.

**Symptom:** grid-class alarms — over/under-voltage, over/under-frequency, no-grid — once in
a storm, or every afternoon like clockwork.

## Check first

1. **Occasional or chronic?** A one-off during grid disturbance self-clears by design; a
   daily pattern needs measurement. {/* CITE: Q-38 §9.5 E101 guidance p.78(print)/p.83(PDF) */}
2. **Measure at the inverter's AC terminals across the problem window** — the terminal
   voltage, not the DB's, is what the inverter sees.
3. **Terminations tight?** Loose AC terminations mimic a bad grid at every load step.

<Warning>
  **Pending Kent validation — do not configure in the field.** \[KNB-VAL-01]
  The India grid-code parameter set for both platforms (V/F windows, reconnect, PF) is under
  confirmation. Until published here: set the grid code only per the Kent-issued parameter
  sheet for the site's DISCOM, and never improvise protection values.
</Warning>

## Escalate when

* The grid is chronically out of band on logged measurements — Kent leads the DISCOM letter;
  bring the readings, timestamps and photos.
* Grid alarms persist with a verified-healthy grid and tight terminations.
* Any request lands to "just widen the limits" — that path runs through utility consent and
  Kent, or not at all.
