Both Kent platforms power ON grid-first and OFF battery-first — the exact reverse. Learn the order once; it is the same logic on every Kent hybrid.
DANGER — stored energy. After the last switch opens, the inverter still holds residual voltage and needs 5 minutes to discharge. Wait 5 minutes before opening any cover.

​
Before you start

  • Tell the customer backup power will stop — printers, routers, medical devices.
  • Have your multimeter and (for any PV work on Kent G3) a clamp ammeter ready.
  • Identify every isolator: grid breaker, backup breaker, inverter DC switch, battery breaker, battery switch/button.

​
Power OFF — battery first

1

Stop the battery

Kent M1: battery button OFF, and switch off any generator source on the GEN port. Kent G3: battery breaker OFF.
2

Open the AC side

Grid breaker OFF (and backup breaker OFF if fitted).
3

Open the PV DC side

Kent G3: confirm string current is below 0.5 A with a clamp ammeter — if higher, wait for irradiance to fall — then turn the DC switch OFF. Kent M1: inverter DC isolator OFF.
4

Wait 5 minutes, then verify dead

Wait the full labelled 5 minutes, then meter-verify no dangerous voltage remains before touching conductors or opening covers.
Pending Kent validation. [KNB-VAL-15] The exact verify-dead voltage threshold for Kent M1 is under confirmation. Until published here: wait the full 5 minutes and meter-verify no dangerous voltage on the DC bus and terminals before any contact — never rely on the wait alone.

​
Power ON — AC first

1

Close the grid AC breaker first

2

PV DC on

Inverter PV DC switch ON.
3

Battery last

Kent M1: battery breaker ON → battery switch ON → battery button ON. Kent G3: battery breaker ON (after first-time HMI setup on a new install).
4

Watch the boot

A clean boot shows no sequence faults; any alarm on Kent G3 → power off and wait 5 minutes before restarting once.

Power ON = AC first; power OFF = battery first — figures KNB-SVG-02 (Kent M1) and KNB-SVG-03 (Kent G3)

Older notes and some videos teach battery-first power-on. That order is wrong for Kent units — both official sequences are AC-first. If a site card disagrees with this page, the card is outdated; report it.

​
Common mistakes

  • Opening the Kent G3 DC switch with string current above 0.5 A — it arcs.
  • Skipping the 5-minute wait because “it’s only a quick look” inside.
  • Leaving the battery ON while working the AC side — the backup port stays live.

When to escalate

Escalate to Kent New Energy service only — through your registered Kent partner channel or the Kent service desk details on your work order. Do not contact any third-party or component-manufacturer support line for a Kent-branded system: tickets outside the Kent channel are not tracked, not covered, and can void warranty handling.
