***

**3.** Kent M1 AC terminal torque is:

* A. 0.5 N·m
* B. 1.2 N·m
* C. 2.5 N·m

***

**4.** Dual PE (protective earth) termination on the Kent M1 AC port is:

* A. Optional — single PE is adequate for residential installations
* B. Required only on TT earthing systems
* C. Mandatory on all Kent M1 installations
* D. Required only when the battery is connected

***

**5.** Kent M1 backup maximum output current by model — 3 kW / 5 kW / 6 kW — is:

* A. 10 A / 20 A / 25 A
* B. 16 A / 32 A / 40 A
* C. 15 A / 25 A / 30 A
* D. 20 A / 30 A / 35 A

***

**6.** The Kent M1 grid-charge function ships from the factory:

* A. Enabled by default for lithium batteries
* B. Disabled by default — enable it deliberately where the design requires it
* C. Controlled automatically by the BMS based on SOC
* D. Enabled only when the battery falls below 20 % SOC

***

**7.** Kent M1 Time-of-Use (TOU) programming uses:

* A. 6 time slots tiling 24 hours, with discharge power set in watts
* B. 6 + 6 windows, with charge/discharge current set in amps
* C. A single day/night pair with a percentage of rated power
* D. 4 slots with start time, end time, and a mode flag only

***

**8.** For Kent M1 parallel systems, the DIP switch scheme at the first and last unit is:

* A. A 2-way switch with both pins ON at first and last unit
* B. No DIP switches — addressing is software-only
* C. A 3-way switch with pins 1 & 3 enabled at first and last unit
* D. A 3-way switch with all three pins ON at every unit

***

**9.** The first step of the Kent M1 power-ON sequence is:

* A. Turn on the battery button switch
* B. Close the PV DC disconnect switch
* C. Close the AC protection switch on the grid side
* D. Press the inverter power key on the display

***

**10.** The Kent M1 GEN port accepts:

* A. A three-phase generator of any rated size
* B. Grid-tied micro-inverters only
* C. A single-phase generator up to 6 600 VA / 30 A
* D. Nothing — the GEN label is a monitoring input only

| Q  | Answer | Why                                                                                                                                                                 |
| -- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 1  | **B**  | The Kent M1 is a single-phase hybrid inverter. One AC grid connection, one AC backup output. Not to be confused with the three-phase Kent G3.                       |
| 2  | **B**  | The Kent M1 maximum PV open-circuit voltage is 500 V. String design must keep Voc at worst-case (cold) temperature below this limit.                                |
| 3  | **B**  | Kent M1 AC terminal torque is 1.2 N·m. The Kent G3 is 4–5 N·m — a common mix-up on mixed-fleet crews.                                                               |
| 4  | **C**  | Dual PE is mandatory on all Kent M1 installations. A single PE connection is not compliant.                                                                         |
| 5  | **C**  | 15 A (3 kW) / 25 A (5 kW) / 30 A (6 kW). Size the essential panel to the specific model's figure — 30 A is only valid for the 6 kW unit.                            |
| 6  | **B**  | Grid-charge ships disabled by default on the Kent M1. Enabling it is a deliberate design choice — not automatic. On outage-first homes, enable it at commissioning. |
| 7  | **A**  | The Kent M1 TOU uses 6 time slots tiling 24 hours, with power set in watts. The Kent G3 uses amps — a common platform-mix error.                                    |
| 8  | **C**  | 3-way DIP switch, pins 1 and 3 enabled at the first and last unit in the parallel chain.                                                                            |
| 9  | **C**  | The Kent M1 power-on sequence: close AC protection switch first. Power-off is the reverse — battery off first.                                                      |
| 10 | **C**  | The Kent M1 GEN port accepts a single-phase generator up to 6 600 VA / 30 A. The Kent G3 GEN port is three-phase only.                                              |
