Questions
1. AC terminal torque: Kent M1 vs Kent G3:- A. 4–5 N·m on both platforms — use the same torque setting
- B. 1.2 N·m (M1) vs 4–5 N·m (G3)
- C. 4–5 N·m (M1) vs 1.2 N·m (G3)

2. Platform phase type: Kent M1 vs Kent G3:
- A. Three-phase on both — different voltage levels only
- B. Single-phase (M1) vs three-phase (G3)
- C. Three-phase (M1) vs single-phase (G3)
- D. Single-phase on both — the G3 is a single-phase unit with three outputs
3. Generator (DG) port compatibility: Kent M1 vs Kent G3:
- A. Three-phase DG on both
- B. Single-phase DG only on both
- C. Single-phase DG ≤ 6 600 VA / 30 A (M1) vs three-phase DG only, feeding backup loads (G3)

4. Time-of-Use (TOU) programming units: Kent M1 vs Kent G3:
- A. Amps on both
- B. Watts on both
- C. Watts, 6 slots tiling 24 h (M1) vs amps, 6 + 6 windows (G3)
- D. Percentage of rated on both
5. Parallel DIP switch scheme: Kent M1 vs Kent G3 — at the first and last unit:
- A. Identical 3-way scheme on both
- B. No DIP switches on either — both use software addressing
- C. 2-way switch with both pins ON (M1) vs 3-way switch with pins 1 & 3 enabled (G3)
- D. 3-way switch with pins 1 & 3 enabled (M1) vs 2-way switch with both pins ON (G3)
6. Acceptable mounting orientation: Kent M1 vs Kent G3:
- A. Both accept vertical or up to 15° back-tilt
- B. Vertical or ≤ 15° back-tilt (M1) vs vertical ± 5° only (G3)
- C. Vertical ± 5° only (M1) vs any angle up to 45° (G3)
- D. Horizontal allowed on both for flat-roof installations
7. The BMS communication cable rule for both platforms is:
- A. Use any straight-through RJ45 patch cable — both platforms accept standard network cables
- B. Use the same crossover cable on both — the Kent Lithium Battery mirrors the inverter BMS RJ45 pinout on both platforms
- C. Use a straight-through cable on the M1 and a crossover cable on the G3
- D. Use a crossover cable on the M1 and a straight-through cable on the G3
8. The CT direction rule that is the same on both platforms is:
- A. Arrow toward the loads, on the backup feed conductor
- B. Arrow toward the grid, clamped on the grid main live conductor
- C. Direction set in software — physical orientation does not matter
- D. Arrow toward the inverter, on the incomer neutral
Answer key
| Q | Answer | Why |
|---|---|---|
| 1 | B | M1 torque is 1.2 N·m. G3 torque is 4–5 N·m. Applying M1 torque to a G3 terminal leaves connections undertightened. Applying G3 torque to an M1 terminal risks stripping the lug. Always check which platform you are on. |
| 2 | B | The Kent M1 is single-phase. The Kent G3 is three-phase. They are not interchangeable — site design, wiring, and protection are all different. |
| 3 | C | The M1 GEN port takes a single-phase DG up to 6 600 VA / 30 A. The G3 GEN port is three-phase only and feeds backup loads — grid-side loads on a G3 site with a generator need an ATS. |
| 4 | C | M1 TOU: watts, 6 slots tiling 24 hours. G3 TOU: amps, 6 + 6 windows. Programming the M1 in amps or the G3 in watts is a real and common commissioning error on mixed-fleet crews. |
| 5 | D | M1: 3-way DIP switch, pins 1 & 3 enabled at first and last unit. G3: 2-way DIP switch, both pins ON at first and last unit. Applying one platform’s scheme to the other disables the parallel communication. |
| 6 | B | M1 accepts vertical or up to 15° back-tilt. G3 is ± 5° of vertical (Kent SOP). The G3 tolerance is tighter — treat it that way on every G3 mount. |
| 7 | B | The same crossover cable rule applies to both platforms. The Kent Lithium Battery mirrors the inverter BMS pinout on both M1 and G3, so a crossover cable is always needed regardless of which platform you are wiring. |
| 8 | B | CT arrow points toward the grid on both platforms. This is the one universal CT rule — it does not change between M1 and G3. |
