Check first
- 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.
- Cross-check against physical truth — use the utility meter, a clamp meter, and the sun’s position.
- 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
| The screen shows | Physical reality check | Likely cause → fix |
|---|---|---|
| Export at night or battery discharging to grid | Utility meter disagrees or confirms | CT reversed — follow Wrong-CT Symptoms |
| 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 |
| Fast, erratic fluctuation with steady physical loads | Loads verified steady with clamp meter | CT direction problem — the Kent G3 FAQ’s own diagnosis for this symptom |
| One phase imports while another discharges | Per-phase load steps with a clamp meter | Phase mapping mismatch — follow Meter & Phase Matching |
| Grid figures frozen | Meter comm alarm on display | RS485 meter link or supply problem — follow Comm Fault |
| SOC frozen at 0% with normal pack voltage | Pack indication light vs SOC on display | BMS comms down — follow Cable Checks |
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.
