# Kent G3 Mounting — Wall, Clearances, and Airflow

> Wall load-bearing requirements, G3 clearance table, the strict ±5° verticality rule, fan airflow left-in right-out, and anchor pull-check.

Before you lift the Kent G3 onto the wall, confirm the structure can carry the load, the clearances around the unit are free, and the fan path is unobstructed. A wrong mount that has to come down costs more time than doing it right the first time.

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

## Before You Start

* The site passes [Choosing the Location](/environment/choosing-the-location): shaded position, ideal ambient ≤ 40 °C, rain and snow not landing directly on the unit. A north-facing wall under an eave is ideal. At least 3 m from flammable substances. Fireproof mounting structure. Not in a living area — fan noise reaches 65 dB(A).
* **Wall:** non-inflammable material, load-bearing capacity **≥ 4× the inverter weight**.
* The heat-sink can reach **75 °C** — consider service access and proximity to passers-by.

## Clearances and Airflow

Fan air **enters on the LEFT** and **exits on the RIGHT**. Both sides must stay clear.

| Clearance                         | Minimum |
| --------------------------------- | ------- |
| To any object (all sides)         | 300 mm  |
| Between two inverters             | 700 mm  |
| In front of the unit              | 500 mm  |
| Bottom of unit to floor or ground | 500 mm  |

Do not store anything on top of or leaning against the inverter. Position the unit so the LEDs are visible during operation.

<Tip>
  The exhaust side (right) must not face a wall return or a corner that recirculates hot air back into the intake. If the layout forces a tight right-side gap, rethink the position before you drill.
</Tip>

## Verticality — the Kent Rule

Mount the inverter **vertical, within ±5°**. Beyond ±5° the output derates. Never forward-tilted and never horizontal.

<Note>
  This is stricter than some other platforms allow. Kent's G3 standard is ±5° — do not carry a more relaxed rule from another platform onto this unit.
</Note>

## Mounting Steps

<Steps>
  <Step title="Mark and drill for the bracket">
    Mark the anchor points on the wall. For brick or masonry, use the supplied expansion bolts. Confirm the marks are level.
  </Step>

  <Step title="Fix the mounting bracket">
    Bolt the back plate level to the wall. Check level in both axes before you move on.
  </Step>

  <Step title="Hang the inverter with two people">
    Two people lift the inverter, align the back bracket with the convex section of the wall plate, and hang it. Confirm it is seated and secure before releasing.
  </Step>

  <Step title="Check verticality and clear access">
    Verify vertical within ±5° with a spirit level or inclinometer. Confirm all clearances are met. Photograph the result. 📷
  </Step>

  <Step title="Anchor pull-check">
    Apply a firm downward pull to the unit — the bracket must not shift or creak. Record pass or fail on the commissioning checklist.
  </Step>
</Steps>

## Common Mistakes

* Unit tilted back beyond ±5° because another platform allows more tilt — the G3 rule is stricter.
* Second inverter placed 300 mm from the first — inverter-to-inverter spacing needs 700 mm.
* Right-side exhaust facing a wall return that recirculates hot air back into the fan intake.
* Single-person lift on a 42 kg unit.
