# Kent G3 Settings Reference — Modes, TOU, and Battery

> Storage modes table, mode options explained, TOU current-based windows, battery threshold ordering rule, zero-export recipe, and Only-PV-power-load.

What every field-relevant Kent G3 setting does, and the Kent rules around it. This page covers the G3 only — parameter names and units differ between the G3 and the Kent M1. Do not carry settings from one platform to the other.

<Warning>
  **For trained and authorized installers only.** The professional menu is password-locked and partner-gated. Grid protection levels load from the grid code — never edit them manually.
</Warning>

## Storage Modes

Modes are exclusive — one at a time. Off-grid also engages automatically on a grid outage and supplies backup loads only.

| Mode              | Load priority         | Supply priority          |
| ----------------- | --------------------- | ------------------------ |
| **Self-use**      | load → battery → grid | PV → battery → grid → DG |
| **Selling first** | load → grid → battery | PV → battery → grid → DG |
| **Off-grid**      | load → battery        | PV → battery → DG        |

## Mode Options

| Setting                 | What it does                                                                                                                                                                  |
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Allow Export**        | Enables feed-in in Self-use. Leave OFF where feed-in is not permitted.                                                                                                        |
| **Max export power**    | Caps feed-in (default 1.1× rated). **If feed-in is not allowed, set this to 0.**                                                                                              |
| **Export calibration**  | −500 to +500 W (default 20 W). Trim slightly negative to eliminate residual export shown by the utility meter.                                                                |
| **Battery reserve**     | 5–95%, default 80%. Below this level the battery stops discharging during on-grid operation.                                                                                  |
| **Allow grid charging** | Grid charges the battery when SOC falls to Force-charge SOC, or when PV cannot meet the set current in a charge window.                                                       |
| **Unbalanced output**   | ON = each phase feeds its own load; one phase can carry up to 50% of total power (15 kW unit → up to 7.5 kW on one phase). OFF = power is split equally at rated/3 per phase. |
| **Grid peak shaving**   | Caps grid draw at the set value by reducing battery charging. Exceeded only to keep the load alive. Set to the site's sanctioned import limit.                                |

<Warning>
  **Pending Kent validation.** \[KNB-VAL-06]

  The firmware default for unbalanced output and the 150% unbalanced-load figure are under bench confirmation. Until published here: do not promise more than 100% of the per-phase rating on any single phase. Record the per-phase test result at commissioning.
</Warning>

## Time of Use (TOU)

Up to **6 charge windows and 6 discharge windows**. Each window sets:

* A **current value in amperes** (not watts — this is the critical difference from the Kent M1)
* A SOC or voltage cut-off
* An enable toggle per window

TOU is available in Self-use and Selling first modes. Grid charges during charge windows only when **Allow grid charging** is also ON.

<Warning>
  **TOU windows on the G3 are current-based (amperes), not power-based (watts).** Crews carrying M1 habits will set the wrong values. Double-check before leaving the site.
</Warning>

## Battery Settings and Functions

<Accordion title="Core thresholds">
  | Setting               | Default             | Notes                                                    |
  | --------------------- | ------------------- | -------------------------------------------------------- |
  | Max charge current    | Per bank sizing     | Set to packs × pack current limit                        |
  | Max discharge current | Per bank sizing     | Set to packs × pack current limit                        |
  | Overdischarge SOC     | 20%                 | Battery stops discharging below this level               |
  | Recovery SOC          | Above overdischarge | Battery resumes discharge once it recovers to this level |
  | Force-charge SOC      | 10%                 | Grid charges battery when it falls to this level         |
  | Max charge SOC        | 100%                | Upper charging limit                                     |

  Ordering rule: **Force-charge SOC \< Overdischarge SOC \< Recovery SOC**. Violating this order causes unexpected charge or discharge stops with no obvious fault code.
</Accordion>

<Accordion title="ECO function">
  When PV is under 100 W and SOC is below the overdischarge threshold, standby power draws from the grid rather than the battery. Reduces unnecessary shallow cycles during overcast days.
</Accordion>

<Accordion title="Battery Healing">
  After a prolonged period at low SOC, the system charges to the Healing SOC before allowing discharge again. This restores SOC measurement accuracy. Normal behaviour — not a fault.
</Accordion>

<Warning>
  **Pending Kent validation — leave battery wake-up at factory values.** \[KNB-VAL-18]

  The battery wake-up voltage range printed in the source manual does not match this platform's 40–60 V battery window — this is a known documentation errata. Until Kent publishes the confirmed range: use the Battery Wakeup switch only. Do not key in any wake-up voltage values from manual text.
</Warning>

## Zero-Export Recipe

Use this sequence on any export-limited site:

<Steps>
  <Step title="Disable export">
    Set **Allow Export = OFF**, or set **Max export power = 0** where the DISCOM requires an explicit numerical cap.
  </Step>

  <Step title="Trim calibration">
    Set **Export calibration** slightly negative if a residual export is visible on the utility meter after step 1.
  </Step>

  <Step title="Witness test">
    With high PV and minimum load running, watch the utility meter for any sustained export. Then step a heavy load and confirm CT sign is correct. Photograph the result. 📷
  </Step>
</Steps>

## Only-PV-Power-Load

This feature is OFF by default and auto-disabled when PV voltage exceeds 510 V. If the load exceeds available PV power, the load shuts off. Auto-restart retries at 3 minutes, then 5 minutes, then 10 minutes. After the third failed restart, a **manual reset is required**. Know this behaviour exists before spending time chasing what looks like a mystery shutdown.

## Common Mistakes

* Feed-in "disabled" by hope alone instead of Allow Export OFF plus Max export power 0 plus a witness test.
* TOU windows set in watts by M1 habit — this platform's windows are **current-based in amperes**.
* Battery reserve dropped to 20% "for more savings" — the first grid outage lands on a nearly empty battery.
* Wake-up voltage values typed from manual text instead of using the switch only — see the validation warning above.
