# Kent M1 GEN Port — Generator, AC-Couple, Smart Load

> Three exclusive roles for the GEN port: diesel generator input, AC-coupled PV inverter, or smart-load output — wiring, LCD settings, and limits.

The Kent M1's GEN port takes one of three exclusive roles: diesel generator input, AC-coupled third-party PV inverter, or smart-load output. You select the role on the LCD — and the selected location must match the physical wiring, or the system misbehaves. Decide the role before you pull cable, because the wiring and the settings have to agree.

<Warning>
  **For trained and authorised installers only.**
</Warning>

## Port limits

These limits apply to all three Kent M1 models regardless of the selected role:

| Parameter          | Value                  |
| ------------------ | ---------------------- |
| Max apparent power | 6600 VA                |
| Max current        | 30 A                   |
| Voltage            | 220/230 V single-phase |

## Role 1 — Diesel generator

The GEN port accepts a **single-phase diesel generator** — the natural pairing for single-phase homes.

Size the DG to fit within the port rating (≤ 6600 VA / 30 A).

**DO4** (16-way strip) is the DG start/stop dry contact — it closes (voltage-free) when the generator start signal is active. **DI4** takes the ATS status feedback from the changeover switch.

Configure the following LCD settings under the DG menu:

| LCD setting            | Description                                                  |
| ---------------------- | ------------------------------------------------------------ |
| DG enable              | Turn the DG function on                                      |
| Connection port        | Must match the physical wiring (GEN port)                    |
| Max input power        | Cap for the connected DG — must be ≤ 6600 VA                 |
| Max DG charge current  | Limits battery charging from the DG                          |
| DG rated power         | The nameplate power of the connected generator               |
| Auto / Manual          | Auto: start at low-SOC threshold, stop at high-SOC threshold |
| Maximum single runtime | Prevents continuous DG run — sets a time ceiling             |
| Forced cooling time    | Run-down period before final stop                            |

<Warning>
  Never allow the hybrid inverter to backfeed a running generator, and never combine a generator with a grid-tied inverter on the same system.
</Warning>

## Role 2 — AC-couple (third-party PV inverter)

Use this role when an existing grid-tied PV inverter is being AC-coupled to the Kent M1 system.

* The Kent M1 controls the coupled inverter using **frequency-watt (Volt-Watt) control** — it shifts frequency linearly toward the disconnect threshold and stops the coupled inverter at the configured stop frequency.
* Configure the **cut-off SOC** (stop charging at this battery level) and the **reconnect SOC** (resume when battery drops to this level).
* The access location is selectable as **GEN port or BACKUP port** — the LCD selection must match the physical wiring.
* Metering for AC-coupled sites uses the 3-CT (single-phase supply) or 6-CT (three-phase supply) meter schemes — see [CT & Meter](/m1/ct-and-meter).

<Warning>
  **Pending Kent validation — do not configure in the field.** \[KNB-VAL-10]
  AC-couple-on-BACKUP behaviour is under bench confirmation. Until published here, do not configure AC-coupling on the backup side. Where AC-coupling is required, use the GEN-port location only.
</Warning>

## Role 3 — Smart load

Use this role to control a non-critical load — a geyser, pump, or similar — based on battery state of charge.

* **Always on when on grid:** the smart load runs whenever grid is present.
* **Cut-off SOC:** shed the smart load when battery SOC drops to this threshold.
* **Reconnect SOC:** restore the smart load when battery recovers to this threshold.

<Tip>
  Smart load is well-suited to a non-critical geyser or water pump that should run only when surplus energy is available, without drawing from the battery below a safe level.
</Tip>

## Common mistakes

* Role wired one way and selected another in the LCD — the source manual is explicit that the wrong access-location selection disturbs system operation.
* DG sized to match the house load instead of the port ceiling — 30 A and 6600 VA is the absolute ceiling for the port.
* Promising DG auto-start to a customer without wiring DO4 — the start signal requires the dry contact.

## 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.
