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.
For trained and authorized installers only. Export settings sit behind partner-gated menus and carry compliance and regulatory consequences.

​
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.

Causes

CauseHow to confirmFix
CT reversed / wrong location / wrong phaseEnergy-Flow Test fails — display reads export at night or with PV offPhysical fix per Wrong-CT Symptoms, then re-witness the export limit
Export settings incomplete or misconfiguredSettings audit against the platform commissioning pageKent M1: Solar Sell must be OFF for zero-export intent; set Max sell power and Sell offset per design (witness test is mandatory before sign-off) · Kent G3: set Allow Export per design; set Max export power = 0 where no feed-in is permitted; use a small negative Export calibration to eliminate residual trickle
Residual trickle exportSmall steady export at high PV with correct CT and settingsKent G3: apply a small negative Export calibration per the manual · Kent M1: use Sell offset to compensate the metering error
CT ratio wrongPower figures are off by a large consistent factorSet ratio exactly per the shipped CT nameplate — never assume the ratio
AC-coupled third-party GT inverterExport continues with the Kent unit fully curtailed; confirmed by site surveyPhysics — not a configuration fix; reset expectations and involve Kent for the compliance design
Blips misread as sustained exportTrace shows spikes only on load steps with no sustained exportExplain per Zero Export — The Concept; battery absorption in progress narrows these blips
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.
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.
