# Zero Export Failing: Utility Meter Shows Unwanted Export

> Export appears on the utility meter despite the limit being set — CT checks, per-platform settings, residual trickle, and the correct witness-test close.

Your goal is to stop sustained export to the grid on a site configured for zero or limited export. Start by distinguishing spikes from sustained export before making any changes.

**Symptom:** the utility meter shows export — or a DISCOM notice arrives — on a site configured for zero or limited export.

<Warning>
  **For trained and authorized installers only.** Export settings sit behind partner-gated menus and carry compliance and regulatory consequences.
</Warning>

## Check first

1. **Spikes or sustained export?** Momentary blips on load steps are the control loop's normal response physics. **Sustained** export above the limit is the fault. Establish the trace shape before anything else.
2. **CT live test** — with grid ON and PV OFF, the display must read import. A reversed or misplaced CT is the number-one cause of apparent export. Run this before touching settings.
3. **Third-party grid-tie inverter on site?** If another GT inverter is connected upstream of the Kent unit's CT, its generation is uncontrollable by the Kent hybrid — this is an expectations case, not a settings case.

On the **Kent M1**, an anti-backflow breach also raises **E105** on the LCD. Treat the E105 alarm as a timestamp for this flow — it does not change the triage.

## Close it properly

A zero-export fix is only closed when you have completed the **witness test against the utility meter**: PV generation high, site load minimised, no sustained export above the configured limit, result photographed into the commissioning record. 📷

Configuration without a utility-meter witness is not a closed ticket.

## Escalate when

* Sustained export persists with the CT proven correct and settings verified — send the settings snapshot and an export trace to Kent service.
* A **DISCOM dispute** is open — escalate to Kent with the commissioning record and witness evidence. The compliance response runs through Kent, not through the installer.

<Note>
  **Escalate to Kent New Energy service only** — through your registered Kent partner channel or the Kent service desk details on your work order. Do not contact any third-party or component-manufacturer support line for a Kent-branded system: tickets outside the Kent channel are not tracked, not covered, and can void warranty handling.
