# Kent M1 Commissioning Checklist: Single-Phase Steps

> Kent M1 Hybrid Inverter commissioning additions — platform pre-checks, power sequence, first-run settings, and backup sizing. Run after Common checklist.

These are the platform-specific additions for the Kent M1 Hybrid Inverter (3 / 5 / 6 kW single-phase). Run the [Common Commissioning Checklist](/checklists/common-commissioning) first — this list never applies to Kent G3.

<Warning>
  **For trained and authorized installers only.** Do not begin platform steps until the Common checklist is fully completed.
</Warning>

## Platform pre-checks

Verify these items before the M1 power-up sequence.

* [ ] **Altitude** — confirm the site is at or below **2000 m**. **Pass:** confirmed. Sites above 2000 m are a Kent G3 or Kent-query case; do not commission M1 above this limit.
* [ ] **Dual PE connected** — both the AC-connector system ground **and** the chassis protective-earth point must be landed; never only one. Seal the chassis terminal with paint after fitting. **Pass:** both PE points landed and photographed. 📷
* [ ] **Backup-port PE grounded** — the Backup port will not supply loads during a grid failure without a separate PE connection. **Pass:** PE continuity verified at the Backup port.
* [ ] **PV within platform limits** — string open-circuit voltage ≤ **500 V**; difference between the two MPPT inputs **\< 250 V**; one string per MPPT only. **Pass:** all measured values logged.

## Power-up and first configuration

Use the on-device LCD throughout. Do not use a user-level session for installer settings.

<Steps>
  <Step title="Power ON in the M1 sequence">
    AC breaker → inverter PV DC switch → battery breaker → battery switch → battery button. **Pass:** clean boot, no faults at startup.
  </Step>

  <Step title="Enter first-run settings in order">
    Time → Meter/CT → Grid standard → Operation mode → Battery type and BMS protocol. Advanced settings require the partner-gated installer password. **Pass:** each screen confirmed and photographed. 📷
  </Step>

  <Step title="Set grid code">
    Set the grid code per the Kent parameter sheet for the site's DISCOM. Never improvise grid protection parameters. **Pass:** grid code set; code and DISCOM name recorded.

    <Warning>**Pending Kent validation.** \[KNB-VAL-01] Grid code parameters are confirmed per DISCOM. Use only the Kent-issued parameter sheet — never improvise grid protection settings.</Warning>
  </Step>

  <Step title="Select Kent Lithium Battery">
    Set the LV battery-brand protocol family per the Kent battery pages and confirm a live SOC is displayed. Use the exact on-screen label shown on the Kent battery pages; the crossover cable and pairing rules apply. **Pass:** battery model selected; live SOC visible and updating. 📷

    <Warning>**Pending Kent validation.** \[KNB-VAL-05] The exact on-screen battery-brand label for Kent M1 is under confirmation. The crossover cable rule and pairing requirements are confirmed.</Warning>
  </Step>
</Steps>

## Backup sizing honesty

Check the backup load before signing off. There is no grace margin on this platform.

* [ ] **Backup loads within the per-model continuous rating** — maximum continuous backup current is **15 A (3 kW model) / 25 A (5 kW model) / 30 A (6 kW model)**, corresponding to 3300 / 5500 / 6600 VA. **Pass:** measured backup load at or below the model figure.

<Warning>
  **Pending Kent validation — do not configure in the field.** \[KNB-VAL-02]
  Backup surge capacity for the Kent M1 is under confirmation. Until this is published here, size all backup loads to rated power only (3300 / 5500 / 6600 VA) and do not promise motor-start headroom to the customer.
</Warning>

| Model        | Max backup current | Continuous backup VA |
| ------------ | ------------------ | -------------------- |
| Kent M1 3 kW | 15 A               | 3300 VA              |
| Kent M1 5 kW | 25 A               | 5500 VA              |
| Kent M1 6 kW | 30 A               | 6600 VA              |

* [ ] **Transfer behaviour test** — open the grid breaker with real essential loads connected. **Pass:** loads ride through the transfer; do not quote a transfer time figure to the customer.

<Note>**Pending Kent validation.** \[KNB-VAL-03] The Kent M1 transfer time in milliseconds is under confirmation. Until published here: do not quote a transfer time figure to the customer.</Note>

## Shutdown drill (before leaving)

Run this before you leave the site. Verify the unit restarts cleanly.

* [ ] **Power OFF in the M1 sequence** — battery button OFF (and GEN source off if used) → AC breaker OFF → DC isolator OFF → **wait the labelled 5 minutes**. Then power back ON in the full M1 sequence. **Pass:** clean shutdown and clean restart with no fault codes.

## Common mistakes

* Connecting only one PE point and skipping the chassis earth — dual PE is mandatory on this platform.
* Promising motor-start headroom on backup without checking the per-model backup current rating.
* Carrying Kent G3 menu habits — passwords, parallel DIP positions, battery menu entries — onto the M1 platform.
