Connecting the battery bank to the Kent G3 covers the dual-input terminal layout, the per-cable current ceiling that forces dual cabling on the 15 kW model, and the exact pairing steps for the Kent Lithium Battery.
DANGER — verify the battery is OFF and reads 0 V DC at both cable ends before connecting anything. Follow the battery’s own shutdown procedure before you touch the terminals.

​
Power Cabling

The G3 provides two inputs per pole — BAT+ has two terminals, BAT− has two terminals — four M8 screws total.

Recommended cable2 AWG (33.62 mm²) × 4
Strip length13 mm
Lug typeR-type crimped (do not over-crimp)
Max current per input200 A
Recommended max per cable≤ 150 A
The 15 kW model’s 290 A battery maximum exceeds 150 A per cable. You must run dual cables per pole — one cable per BAT+ input and one cable per BAT− input. A single cable on a 15 kW unit will overheat the lugs at full charge or discharge current.
The battery fuse inside the wire box is replaceable only by Kent-authorized service technicians. Never attempt a field repair.

​
Pairing the Kent Lithium Battery

The Kent Lithium Battery (F1 family) is confirmed compatible and recommended with the Kent G3. On the battery-model screen, select the LV Pylon-family entry (PYLON_LV). Never select the HV entry — it is for a different battery voltage range entirely.

​
Minimum Packs per Model

The binding constraint is charge current, not capacity. Fewer packs than the matrix specifies runs the system at BMS-limited current with no fault displayed — you will not see an error, but the inverter will not charge at full rate.

After sizing, set the inverter Max charge/discharge current to packs × the pack’s current limit. Multiple packs parallel at a DC busbar or combiner, up to 16 packs per bank. The master pack’s CAN port connects to the inverter. Keep each inverter cable at ≤ 150 A. Two F1-16080 packs on a Kent G3 15KW map directly onto the 2+2 terminals at ≤ 145 A per cable.

​
CAN Communication Cable

The comm cable is a 4-5 crossover — a 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 CAN failure alarm at power-up. If you must re-terminate in the field, swap pins 4 and 5 at one end — never “fix” it in the menus.
Route the BMS cable through COM2 or COM3 to the BMS RJ45 terminal on the 16-pin block. In parallel-inverter systems, use one shared battery bank. Its BMS connects to the master inverter only.

​
Common Mistakes

  • Single cable per pole on a 15 kW unit — 290 A over a single 150 A-class cable overheats the lugs.
  • Straight LAN patch lead used as the BMS cable — guaranteed CAN failure with this pairing.
  • Bank sized by kWh only — charge current is what determines the minimum pack count.
  • Attempting a field repair of the wire-box battery fuse.
