Connecting the battery bank to the Kent M1 requires the right cable cross-section, a properly fitted ferrite ring, and a mandatory DC-rated breaker — and if you are pairing the Kent Lithium Battery, the comm cable has a pin-swap that will catch you if you use a standard patch lead. Read everything on this page before you touch the battery terminals.
DANGER — a battery bank cannot be switched off at the source. Verify polarity before closing anything, keep all tools insulated, and never work on live terminals with the battery breaker closed.

​
Before you start

  • Confirm the battery bank is designed to the minimum-pack matrix — see Pairing the Kent Lithium Battery below. An undersized bank runs at BMS-limited current with no fault displayed.
  • The battery interface accepts Li-ion or lead-acid, 40–60 V DC. BMS communication runs over CAN.

Power cabling

ModelCable sizeTerminal torqueCable OD range
Kent M1 3KW16 mm² (6 AWG)4 N·m11–16 mm
Kent M1 5KW35 mm² (2 AWG)4 N·m13–18 mm
Kent M1 6KW35 mm² (2 AWG)4 N·m13–18 mm
Verify polarity between battery terminals and inverter terminals — check twice, close once. Ferrite ring: the supplied magnetic ring goes on the battery input line, single pass only, secured with a cable tie. Do not loop the cable through multiple turns.

​
The mandatory battery DC breaker

A DC-rated battery breaker is mandatory on every installation:
ModelMinimum currentMinimum voltage
Kent M1 3KW≥ 90 A≥ 60 V DC
Kent M1 5KW≥ 160 A≥ 60 V DC
Kent M1 6KW≥ 180 A≥ 60 V DC
An AC-rated breaker on the battery circuit is not acceptable. The breaker must be rated for DC at the voltages and currents listed above.

​
Pairing the Kent Lithium Battery

The Kent Lithium Battery (F1 family) is confirmed compatible and recommended with the Kent M1. The table below shows the minimum number of packs per M1 model — charge current is the binding constraint. Fewer packs than this minimum runs the whole system at BMS-limited current, with no fault or alarm displayed.
Battery modelKent M1 3KWKent M1 5KWKent M1 6KW
F1-5120 (5.12 kWh)233
F1-11780 (11.78 kWh)11 (≈96 % charge current) or 2 for full2
F1-16080 (16.08 kWh)111
If the installed bank is below the matrix minimum, set the inverter Max charge / discharge current to packs × pack limit in the battery settings page.
The comm cable is a 4-5 crossover — a standard straight RJ45 patch lead will never communicate. The Kent battery RJ45 carries CAN-L on pin 4 and CAN-H on pin 5; the inverter BMS port expects CAN-H on pin 4 and CAN-L on pin 5. Use only the labelled Kent battery comm cable.Symptom of a straight cable: battery comm faults immediately at first power-up.Field fallback if the labelled cable is not available: cut one end and re-terminate with pins 4 and 5 swapped exactly as the source manual instructs for pin-sequence mismatches — never attempt to “fix” this in menus.
Multiple packs parallel at a DC busbar or combiner, up to 16 packs per bank, addressed by DIP switch. Connect one master pack’s CAN port to the inverter — not all packs. Set all pack addresses before power-up per the battery guide.
Pending Kent validation. [KNB-VAL-05] The exact Kent M1 on-screen battery-brand label and the F1 cable-kit contents are under confirmation. Pairing, the minimum-pack matrix, and the 4-5 crossover rule are confirmed. Until published here: select the Pylon-family entry in the BMS-protocol list per the commissioning page and use only the labelled Kent comm cable.

​
Lead-acid banks

Fit the supplied PT1000 temperature sensor on the battery casing — side or top, away from the terminals — and land the leads into the TEMP terminals on the 16-way strip. Set the lead-acid parameters (float, boost, equalization, compensation) in the battery settings page — see Kent M1 Settings Reference.

​
Common mistakes

  • Standard LAN patch lead used as the BMS cable — guaranteed comm failure on this pairing.
  • Bank sized by kWh only, ignoring charge current — results in chronic derating with no alarm shown.
  • Ferrite ring left in the box, or looped multiple turns instead of a single pass.
  • Battery breaker skipped or AC-rated — it must be DC-rated and sized per the table above.

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.
