What every field-relevant Kent M1 LCD setting does, and the Kent rules around it. This page never applies to the Kent G3 — parameter names and units differ between platforms.
For trained/authorized installers only. Advanced pages are password-locked (partner-gated). Grid protection points may be changed only with utility consent.

​
Work modes (System Setting)

For lithium batteries targets are in SOC; for other types, in voltage.

​
Time of Use (TOU)

  • 6 time slots that must tile the full 24 hours; slot boundaries are linked — changing one end moves its neighbour. Each slot: Idle / Charge / Discharge, a Max Power in watts, a target SOC (Li) or voltage (lead-acid), and day-of-week selection.
  • In Sell First, the battery may discharge to the grid even inside a charge window if SOC exceeds the set point.

​
Battery settings

  • Battery type, capacity, max charge current, max discharge current, BMS protocol. Set max currents to the bank’s real capability when below the inverter maximum — see Battery Wiring.
  • Charging from grid is DISABLED by default. For outage-first Indian sites, enable it deliberately and set the max grid-charge current — otherwise the battery may be empty when the first cut comes.
  • Shutdown / Warn / Restart SOC: inverter shuts down below Shutdown, alarms below Warn, resumes AC output at Restart.
  • Activate Bat: timed wake-up that prevents deep discharge on idle systems.
  • Lead-acid page: float / constant-voltage / equalization voltages, equalization interval and duration, temperature compensation (PT1000), and cable-impedance compensation.

​
Zero-export stack

An anti-backflow breach raises E105 on the LCD.
Pending Kent validation — witness test mandatory. [KNB-VAL-07] The exact zero-feed behaviour of “Max sell power = 0” is under bench confirmation. Until published here, every export-limited site gets the zero-export witness test before sign-off.

​
Grid settings

  • Safety code selection confirms with “Setting” → “OK”. Grid pages expose connect/reconnect voltage-frequency windows and slopes, reconnection delay, PF, the 10-minute overvoltage threshold, and two-level OV/UV/OF/UF thresholds with detection times. Change protection points only with utility consent, and only per the Kent parameter sheet. [KNB-VAL-01]

​
Advanced page (partner-gated unlock)

Parallel switch, number of parallel inverters, master/slave role, multi-inverter-one-pack option, feedback source, Meter CT orientation and CT Ratio; DRM enable, NPE Relay Check, GridSeamlessSwitch, insulation-protection enable, enclosure grounding test, NPE voltage threshold, AFCI enable/clearance, system self-check.
If a value you expect is not printed here, check for a KNB-VAL block — it is pending confirmation, not hidden.

​
Common mistakes

  • Grid charging left at default OFF on a backup-first site.
  • TOU slots that don’t tile 24 h — the linked boundaries fight back.
  • “Solar Sell ON, Max sell power 0” configured without the witness test. [KNB-VAL-07]
  • Editing grid protection thresholds without utility consent.
