# Kent M1 Commissioning — Power Sequence and First-Run Setup

> Pre-power checklist, exact AC-first power-on sequence, first-run LCD configuration order, and function tests before signing off a Kent M1 site.

Commissioning the Kent M1 happens entirely on the **on-device LCD** — no app, no laptop. Work through this page in order: pre-checks first, then the power-on sequence, then the configuration items, and finally the function tests. The pass/fail evidence lives in the M1 Commissioning Checklist — photograph every screen you configure.

<Warning>
  **For trained and authorised installers only.** Advanced parameters are password-locked; the password is partner-gated and is never shared outside authorised crews.
</Warning>

## Pre-power checklist

Complete all five items before you close any breaker:

* [ ] Siting correct — no direct sun on the unit, no flammables nearby, serviceable, adequate ventilation space.
* [ ] PE wire, DC cables, AC cables, and comm cables all connected correctly with terminals firm.
* [ ] Cables tied, routed without interference, insulation undamaged throughout.
* [ ] **Unused AC/DC and communication ports are blocked off.**
* [ ] AC voltage and frequency at the grid connection point meet grid-connection requirements.

## Power ON — the M1 sequence

<Warning>
  **AC first ON, battery first OFF.** This sequence is specific to the Kent M1. Do not use a sequence from another platform or a general inverter habit.
</Warning>

<Steps>
  <Step title="Close the AC protection switch">
    Close the AC protection switch on the inverter's AC output side.
  </Step>

  <Step title="Close the PV DC switch">
    Close the inverter's PV DC disconnect switch.
  </Step>

  <Step title="Close the battery DC breaker">
    Close the battery-side DC breaker.
  </Step>

  <Step title="Turn on the battery switch">
    Turn on the battery switch.
  </Step>

  <Step title="Press the battery button switch">
    Press the battery power button switch on the inverter.
  </Step>
</Steps>

**Power OFF is the exact reverse: step 5 → step 1, battery first.** For any service power-off, follow the Isolation & Shutdown procedure and wait the **labelled 5 minutes** before opening any enclosure.

## First-run configuration — in this order

On first commissioning the LCD prompts you through these settings. Complete them in sequence:

<Steps>
  <Step title="Set inverter time">
    Set the RTC date and time. Choose 12 h or 24 h format as preferred.
  </Step>

  <Step title="Configure meter / CT">
    Set CT orientation to **towards the grid**. Set CT ratio exactly per the nameplate on the shipped CT. \[KNB-VAL-08]
  </Step>

  <Step title="Select grid standard">
    Select the safety code for your jurisdiction, then press **"Setting"** to confirm. The button must show **"OK"** — if it does not, the selection has not taken effect. Set only per the Kent parameter sheet. \[KNB-VAL-01]
  </Step>

  <Step title="Set operation mode">
    Select the mode for the site design: Self Use, Sell First, Back Up, or Custom. See [Kent M1 Settings Reference](/m1/settings-reference).
  </Step>

  <Step title="Configure battery type and BMS protocol">
    For the Kent Lithium Battery, select the **Pylon-family entry** in the BMS-protocol list. Confirm **live SOC reading on the LCD** before closing the job. 📷 \[KNB-VAL-05 — exact on-screen label under confirmation; pairing and crossover-cable rule are confirmed]
  </Step>
</Steps>

<Note>
  **LCD navigation basics:** ESC = back, Up/Down = page scroll, **hold ENTER for 5 seconds = LCD reset**. Screen timeout defaults to 2 minutes; brightness adjustable 10–100 %. Parameter changes require cancelling "Lock out all change" in Basic Setting first — this requires the partner-gated password.
</Note>

## Function tests before sign-off

Run every test below before leaving site:

<CardGroup cols={2}>
  <Card title="Battery both ways">
    Force a charge cycle and a discharge cycle. Confirm currents are within the platform limits and within the installed pack limits.
  </Card>

  <Card title="CT sanity check">
    Grid on, PV off → display must show import. Energise a heavy load and confirm the sign and magnitude respond correctly. 📷
  </Card>

  <Card title="Backup transition">
    Open the grid breaker with real essential loads running. Loads must ride through. Do not quote or promise a specific transition time in milliseconds. \[KNB-VAL-03]
  </Card>

  <Card title="Zero-export witness">
    On export-limited sites: high PV, low load, watch the utility meter confirm no feed-in to the grid. \[KNB-VAL-07] — settings on the [Settings Reference](/m1/settings-reference) page.
  </Card>
</CardGroup>

<Info>
  **Derating awareness:** direct sun on the unit, high ambient temperature, an output-percentage cap setting, over-frequency grid events, and high input voltage or current all derate output by design. Check these conditions before suspecting a hardware fault on a site that "isn't producing enough."
</Info>

## Common mistakes

* Powering battery-first because "that's how all inverters work" — the Kent M1 is AC-first ON, battery-first OFF.
* Skipping the "Setting → OK" confirmation on the grid code — the selection does not take effect without that confirmation.
* Leaving site without a full parameter screenshot set archived against the unit serial number.

## When to escalate

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.
