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.

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.
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.

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.
