Commissioning the Kent M1 happens entirely on the on-device LCD — screen, touch and keypad. This page is the flow; the pass/fail evidence lives in the M1 Commissioning Checklist.
For trained/authorized installers only. Advanced parameters are password-locked; the password is partner-gated and never shared outside authorized crews.

​
Before you start

Run the pre-power-on inspection:
  • Siting correct (no direct sun, no flammables, serviceable, ventilation space).
  • PE wire, DC cables, AC cables and comm cables connected correctly, terminals firm.
  • Cables tied, routed without interference, insulation undamaged.
  • Unused AC/DC and communication ports blocked off.
  • AC voltage and frequency at the grid connection meet grid-connection requirements.

​
Power ON — the M1 sequence

Kent M1 power ON = AC first; power OFF = battery first (exact reverse) — figure KNB-SVG-02

  1. Close the AC protection switch on the inverter’s AC output side.
  2. Close the inverter’s PV DC disconnect switch.
  3. Close the battery-side DC breaker.
  4. Turn on the battery switch.
  5. Press the battery button switch.
Power OFF is the exact reverse (5 → 1), battery first. For service power-off, follow Isolation & Shutdown and wait the labelled 5 minutes before opening anything.

​
First-run configuration — in this order

On first commissioning the LCD asks for these, in order:

Kent M1 display navigation mock-up (keys and menu tree) — figure KNB-SVG-09

  1. Inverter time — RTC date and time (12/24 h format optional).
  2. Meter / CT setting — CT orientation is towards the grid; CT ratio exactly per the shipped CT nameplate. [KNB-VAL-08]
  3. Grid standard — select the safety code, then press “Setting” to confirm; the button shows “OK” on success. Set only per the Kent parameter sheet. [KNB-VAL-01]
  4. Operation mode — Self Use / Sell First / Back Up / Custom per the site design; see Settings Reference.
  5. Battery type + BMS protocol — for the Kent Lithium Battery select the Pylon-family entry in the BMS-protocol list and confirm live SOC on the LCD before closing the job. [KNB-VAL-05 — exact on-screen label under confirmation; pairing and the crossover-cable rule are confirmed] 📷
LCD basics: ESC = back, Up/Down = pages, hold ENTER 5 s = LCD reset. Screen timeout defaults to 2 minutes; brightness 10–100 %. Parameter changes first require cancelling “Lock out all change” in Basic Setting (password — partner-gated).

​
Function tests before sign-off

  • Battery both ways: force a charge and a discharge; currents within the platform and pack limits.
  • CT sanity: grid on, PV off → display shows import; heavy-load step → correct sign. 📷
  • Backup transition: open the grid breaker with real essential loads — loads ride through; quote no milliseconds figure. [KNB-VAL-03]
  • Zero-export witness on export-limited sites: high PV, low load, watch the utility meter. [KNB-VAL-07] — settings on the Settings Reference page.
  • Derating awareness: direct sun, high temperature, an output-% setting, over-frequency and high input voltage/current all derate output by design — check these before suspecting hardware.

​
Common mistakes

  • Powering battery-first because an old habit said so — this platform is AC-first ON, battery-first OFF.
  • Skipping the “Setting → OK” confirmation on the grid code — the selection does not take effect without it.
  • Leaving the site without a full parameter screenshot set archived per serial number.
