Questions

1. The Kent G3 Hybrid Inverter is a:
  • A. Single-phase platform with a three-phase battery input
  • B. Three-phase platform — three-phase grid, three-phase output, single-phase backup
  • C. Three-phase platform with three-phase grid and three-phase backup
  • D. Three-phase platform, grid-tied only — no battery
2. The maximum PV string open-circuit voltage (Voc) the Kent G3 accepts is:
  • A. 500 V
  • B. 600 V
  • C. 850 V
  • D. 1 000 V
3. Kent G3 AC terminal torque is:
  • A. 1.2 N·m
  • B. 2 N·m
  • C. 4–5 N·m
  • D. 8 N·m
4. On the Kent G3 10 kW and 12 kW models, the MPPT input current ratings are:
  • A. 40 A + 40 A (symmetric)
  • B. 20 A + 20 A (symmetric)
  • C. 20 A + 40 A (asymmetric)
  • D. 10 A + 60 A (asymmetric)
5. The Kent G3 PV DC switch may only be operated when the string current is below:
  • A. 2 A
  • B. 0.5 A
  • C. 5 A
  • D. Any value — the DC switch is rated for full-load interruption
6. The Kent G3 default battery reserve setting is:
  • A. 20 %
  • B. 50 %
  • C. 80 %
  • D. 100 %
7. Kent G3 Time-of-Use (TOU) programming sets charge and discharge power in:
  • A. Watts, same as the Kent M1
  • B. Amps — current, not power
  • C. A percentage of rated output
  • D. A fixed day / night mode only
8. The maximum number of identical Kent G3 units that may be connected in parallel is:
  • A. 4, any model mix
  • B. 8, with a dedicated combiner
  • C. Unlimited, limited only by grid capacity
  • D. 6 — different G3 models must never be paralleled
9. In the Kent G3 battery menu, the correct entry for the Kent Lithium Battery is:
  • A. Any generic lithium entry — they are equivalent
  • B. The HV battery entry
  • C. The PYLON_LV entry
  • D. No Battery — BMS is auto-detected
10. The Kent G3 GEN port is designed for:
  • A. A single-phase generator of any size
  • B. A three-phase generator feeding backup loads — grid-side loads need a separate ATS
  • C. Grid-tied micro-inverters only
  • D. A single-phase generator up to 6 600 VA / 30 A

Answer key

QAnswerWhy
1CThe Kent G3 is a three-phase platform: three-phase grid input and three-phase backup output. Not single-phase in any configuration.
2DThe Kent G3 maximum PV Voc is 1 000 V — twice the M1 limit. String design must keep worst-case Voc below this figure.
3CKent G3 AC terminal torque is 4–5 N·m. The Kent M1 is 1.2 N·m — the most commonly confused spec on mixed-fleet crews.
4CThe 10 kW and 12 kW G3 models have asymmetric MPPTs: 20 A on MPPT1 and 40 A on MPPT2. The 15 kW model is 40 A + 40 A.
5BThe 0.5 A rule applies to both the M1 and G3 DC switches. Operating under load risks a sustained DC arc.
6CThe Kent G3 default battery reserve is 80 %. A G3 that appears stuck at 80 % SOC on-grid is showing default behaviour, not a fault. Adjust the reserve to the design value if it differs.
7BKent G3 TOU sets charge/discharge in amps. The Kent M1 uses watts. Confusing these causes incorrect TOU programming across platforms.
8DMaximum 6 identical Kent G3 units in parallel. Different G3 models must never be mixed in a parallel chain.
9CSelect the PYLON_LV entry for the Kent Lithium Battery on the G3. Selecting the wrong entry causes BatName-FAIL and prevents BMS communication.
10BThe Kent G3 GEN port is three-phase only and feeds backup loads. Grid-side loads require a separate automatic transfer switch (ATS).
