Commissioning the Kent G3 runs entirely on the on-device HMI — the screen and four keys (ESC, UP, DOWN, ENTER). This page is the step-by-step flow. Pass/fail evidence belongs in the G3 Commissioning Checklist.
For trained and authorized installers only. The professional and advanced menus are password-locked. The password is partner-gated and is never shared outside authorized crews.

​
Pre-Power Checklist

Before closing any breaker, confirm all five:
  • Unit firmly mounted, accessible for service, ventilation space clear, nothing on top
  • Inverter and all 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

1

Measure DC voltages

Measure PV string voltage and battery DC voltage. Confirm polarity on both. Do not proceed if either is outside the platform envelope.
2

Measure grid AC voltage and frequency

Confirm grid voltage and frequency are within the local standard before closing any AC breaker.
3

Close the external grid AC breaker

The control board powers up. Wait for the HMI to initialize.
4

Complete the Quick Setting

Run the first-time Quick Setting flow (below) before enabling DC sources.
5

Close the PV DC switch, then the battery breaker

Verify string current is below 0.5 A before operating the DC switch — see 0.5 A DC-switch rule. Close the PV DC switch first, then close the battery breaker. The system starts. Confirm the OPERATION LED moves from flashing to solid.
Power OFF is the exact reverse — battery breaker first, then PV DC switch, then grid AC breaker. Wait for the device to fully power down before any work. If an alarm shows, power off and wait 5 minutes before one restart attempt. If the alarm persists, escalate — do not cycle repeatedly.

​
Quick Setting — In This Order

The HMI walks you through Quick Setting on first commissioning. Complete each step in sequence before moving to the next.
1

Set inverter time

Enter the current date and time. Wrong time corrupts TOU windows and monitoring logs.
2

CT / Meter setting

Select CT scheme or meter scheme. Set:
  • Installation location: Grid side (standard) / Load side / Grid + PV inverter
  • CT direction: Forward if installed correctly. Select Reversal only to correct a physically reversed CT — but fix the hardware, do not hide a wiring error in software.
  • CT ratio: Set exactly to the value on the shipped CT’s nameplate.
3

Grid code

Select only per the Kent parameter sheet for the site’s DISCOM. Do not enter grid protection values manually.
4

Storage mode

Select Self-use, Selling first, or Off-grid. Modes are exclusive — one at a time. See Settings Reference.
5

Battery setting

Select the battery brand entry. For the Kent Lithium Battery: PYLON_LV. Set max charge and discharge current to the bank’s capability. Confirm live SOC is displayed on the screen before closing the job. 📷
CT ratio confirmation is pending — read the ratio off the shipped CT’s nameplate and set exactly that value. [KNB-VAL-08]
Grid code selection is subject to DISCOM approval — use only the Kent-issued parameter sheet. [KNB-VAL-01]
Selecting no battery model or the wrong model raises a battery-name failure alarm. “No Battery” and “No Meter” exist only to suppress alarms when that hardware is genuinely absent — do not use them to avoid setting up connected hardware.Default SOC values 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. Violating this order causes unexpected charge or discharge stops.

​
Function Tests Before Sign-Off

Complete all of the following and photograph the results:
  • Battery charge and discharge: force charge then force discharge; confirm currents are within platform and pack limits. 📷
  • CT sanity: grid on, PV off → all three phases showing import. Step a known load per phase and confirm each phase responds on its own CT. 📷
  • Per-phase heavy-load test and record unbalanced-output state. See the unbalanced-output validation warning in Settings Reference — do not promise more than 100% of per-phase rating until confirmed.
  • Backup transition: open the grid breaker with essential loads running — loads ride through the transfer with no interruption; confirm clean return when grid is restored.
  • Zero-export witness on export-limited sites — see Settings Reference.
  • Parallel sites: master address = 1, slaves sequential; DIP pins ON at chain ends only; every unit has its own datalogger stick fitted.

​
Common Mistakes

  • DC switch operated without the 0.5 A clamp-meter check.
  • CT ratio assumed at 3000 when the box kit shipped with the 2000-ratio CT — always read the nameplate.
  • “Reversal” selected to hide a physically backwards CT instead of re-clamping it correctly.
  • Carrying Kent M1 habits — menu password, DIP positions, TOU units set in watts — onto this platform.
