Fixing the Kent G3 to the wall: load-bearing, clearances that respect the fan path, and the verticality rule Kent enforces.
For trained/authorized installers only.

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

  1. Mark and drill for the bracket; for brick walls use the supplied expansion bolts.
  2. Fix the mounting bracket level to the wall.
  3. Two people lift the inverter, align the back bracket with the convex section of the wall bracket, hang, and confirm it is secure.
Pass check: spirit-level/inclinometer photo, anchor pull-check, clearances taped and photographed. 📷

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.
