# Display Shows Wrong Energy Flow: Reading the Pattern

> Energy-flow screen contradicts physical reality — pattern-to-cause table, know the screen you're reading, and when to escalate on Kent hybrid sites.

Your goal is to identify which sensor or comm link is feeding the display the wrong number. Displays report what their inputs tell them — fix the input and the display fixes itself.

**Symptom:** the energy-flow screen contradicts reality — export at night, zero PV in full sun, load at 0 W with the house running, or battery arrows pointing the wrong way.

## Check first

1. **Which reading is impossible, exactly?** One wrong figure implicates its own sensor. All figures wrong together implicates the sensing chain at the grid connection point.
2. **Cross-check against physical truth** — use the utility meter, a clamp meter, and the sun's position.
3. **Any alarm alongside the wrong flow?** A flow oddity plus an alarm string means the alarm's flow leads — work the alarm first.

## Pattern → cause

| **Load reads 0 W** with the house clearly running                 | Clamp meter on the incomer shows current flowing              | CT is clamped around both L and N conductors — re-clamp around the live conductor only                                  |
| **PV reads 0 W in full sun**                                      | Per-string voltage on the platform's PV data page vs expected | PV isolator off, string fault, or connector damage — check strings per the platform PV page; Kent M1 note **E300–E305** |
| **Numbers absurd by a large factor** (e.g. 10× or 100× real load) | Known-load sanity check fails                                 | CT ratio wrong — set ratio exactly from the CT nameplate                                                                |

## Know the screen you're reading

Misreading the display causes half these tickets. The **Kent M1 LCD** cycles through separate data pages: PV, Battery, Inverter, GEN, Grid, and Load — not all data is on one screen. The **Kent G3 HMI** shows a combined flow diagram with per-phase tabs. A full guided tour of both displays is at [Display Walkthrough](/handover/display-walkthrough).

<Note>
  **Displays report; they rarely lie on their own.** A wrong-flow reading is almost always a wrong input — CT, meter, or comms — not a faulty screen. Fix the sensing and the picture fixes itself. If an impossible reading persists after the full sensing chain is proven, capture photos and escalate rather than reinterpreting the screen.
</Note>

## Escalate when

* A physically-proven sensing chain still yields an impossible reading on the display.
* Flow anomalies coincide with internal-fault alarm codes — the alarm code's triage flow leads, not this page.

<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.
