Before you start
- Site passes Choosing the Location: shaded (ideal ambient ≤ 40 °C), rain and snow not landing directly on the unit — a north-facing wall under an eave is the manual’s ideal; ≥ 3 m from flammable substances; fireproof mounting structure; not in a living area (fan noise up to 65 dB(A)).
- Wall: non-inflammable material with load-bearing ≥ 4× the inverter weight.
- Heat-sink can reach 75 °C — mind service access and passers-by.
Clearances and airflow
Kent G3 mounting clearances — figure KNB-G3-CR-03
- Fan air enters on the LEFT and exits on the RIGHT — keep both sides clear.
- ≥ 300 mm to objects; ≥ 700 mm between inverters; ≥ 500 mm in front; bottom ≥ 500 mm above the floor or ground.
- Nothing stored on top of or leaning against the unit; LED visibility considered.
Verticality — the Kent rule
Mount vertical within ±5°. Beyond ±5° the output derates. Never forward-tilted or horizontal.Mounting steps
- Mark and drill for the bracket; for brick walls use the supplied expansion bolts.
- Fix the mounting bracket level to the wall.
- Two people lift the inverter, align the back bracket with the convex section of the wall bracket, hang, and confirm it is secure.
Common mistakes
- Unit tilted back “like the other platform allows” — Kent’s G3 rule is vertical ±5°.
- Second inverter mounted 300 mm away — inverter-to-inverter needs 700 mm.
- Exhaust side (right) facing a wall return that recirculates hot air.
