Commissioning the Kent G3 happens on the on-device HMI — the screen and its four keys (ESC, UP, DOWN, ENTER). This page is the flow; pass/fail evidence lives in the G3 Commissioning Checklist.
For trained/authorized installers only. The professional/advanced menu is password-locked; the password is partner-gated and never shared outside authorized crews.

​
Before you start

  • Unit firmly mounted, accessible for service, ventilation space clear, nothing on top.
  • Inverter and accessories correctly connected; cables routed safely and protected.
  • Warning labels affixed and durable.
  • Antenna fitted to its port.
  • Clip-on DC ammeter in the kit — the 0.5 A DC-switch rule applies to every DC-switch operation.

​
Power ON — the G3 sequence

Kent G3 power ON = AC first; power OFF = battery first (exact reverse) — figure KNB-SVG-03

  1. Measure PV string and battery DC voltage; confirm polarity.
  2. Measure grid AC voltage and frequency — within the local standard.
  3. Close the external grid AC breaker — the control board powers up.
  4. Complete the first-time Quick Setting (below).
  5. Close the inverter PV DC switch and the battery breaker — the system starts.
Power OFF is the reverse, battery first. Wait until the device fully powers down before any work; if any alarm shows, power off and wait 5 minutes before one restart — if it persists, escalate, do not cycle.

​
Quick Setting — in this order

On first commissioning the HMI walks the Quick Setting sequence:

Kent G3 HMI navigation mock-up (indicators, 4 keys, Quick Setting) — figure KNB-SVG-10

  1. Inverter time — date and time.
  2. CT / Meter setting — select CT or meter; set the installation location (Grid side / Load side / Grid + PV inverter — grid connection point is the standard); CT direction (correctly installed = Forward; select Reversal only to correct a physically reversed CT); CT ratio exactly per the shipped CT nameplate. [KNB-VAL-08]
  3. Grid code — only per the Kent parameter sheet for the site’s DISCOM; the three-level OV/UV/OF/UF protection sets load from the grid code — no manual entry. [KNB-VAL-01]
  4. Storage mode — Self-use / Selling first / Off-grid (exclusive); see Settings Reference.
  5. Battery setting — select the battery brand entry: for the Kent Lithium Battery the LV Pylon-family entry (PYLON_LV); set max charge/discharge current to the bank’s capability; confirm live SOC on the screen before closing the job. 📷
Selecting no battery model (or the wrong one) raises a battery-name failure alarm; “No Battery” / “No Meter” exist to suppress alarms only while that hardware is genuinely absent. Defaults to know: overdischarge SOC 20 %, force-charge SOC 10 %, battery reserve 80 % (range 5–95 %). The ordering rule is Force-charge SOC < Overdischarge SOC < Recovery SOC.

​
Function tests before sign-off

  • Battery both ways: force charge and discharge; currents within platform and pack limits.
  • CT sanity: grid on, PV off → import on all three phases; per-phase load steps → each phase responds on its own CT. 📷
  • Per-phase heavy-load test and unbalanced-output state check. [KNB-VAL-06]
  • Backup transition: open the grid breaker with real essential loads — loads ride through; clean return.
  • Zero-export witness on export-limited sites — settings and the “Max export power = 0” rule on Settings Reference.
  • Parallel sites: master address = 1, slaves sequential; DIP ends ON; every unit’s datalogger fitted.

​
Common mistakes

  • DC switch operated without the 0.5 A clamp check.
  • CT ratio assumed at 3000 when the box kit shipped the 2000-ratio CT. [KNB-VAL-08]
  • “Reversal” selected to hide a physically backwards CT instead of re-clamping it — fix the hardware, use Forward.
  • Carrying Kent M1 habits (menu password, DIP positions, TOU units) onto this platform.
