Work modes
Select the mode in System Setting on the LCD:| Mode | Behaviour |
|---|---|
| Self Use | PV powers loads first; surplus charges the battery; any remainder goes to the grid. Battery covers loads when PV is insufficient. |
| Sell First | Maximises PV feed-in to the grid. |
| Back Up | Battery held at a configured SOC reserve while the grid is present. Prioritises outage readiness. |
| Custom | Site-specific combination of the above behaviours. |
For lithium batteries, targets are entered in SOC (%). For other battery types, targets are entered in voltage (V).
Time of Use (TOU)
TOU lets you schedule when the battery charges, discharges, or idles across the day:- 6 time slots must tile the full 24 hours with no gaps and no overlaps. Slot boundaries are linked — changing one slot’s end time moves the next slot’s start time.
- Each slot contains: Idle / Charge / Discharge selection, Max Power in watts, a target SOC (Li-ion) or target voltage (lead-acid), and day-of-week selection.
Battery settings
| Setting | What to configure |
|---|---|
| Battery type | Select Li-ion or lead-acid |
| Capacity | Total bank capacity in kWh |
| Max charge current | Set to the bank’s real ceiling when below the inverter maximum |
| Max discharge current | Set to the bank’s real ceiling when below the inverter maximum |
| BMS protocol | Select Pylon-family for Kent Lithium Battery [KNB-VAL-05] |
| Grid charge enable | Disabled by default — enable deliberately for outage-first sites |
| Max grid-charge current | Only relevant when grid charge is enabled |
| Shutdown SOC | Inverter stops AC output below this level |
| Warn SOC | Inverter raises an alarm below this level |
| Restart SOC | Inverter resumes AC output when battery recovers to this level |
| Activate Bat | Timed wake-up to prevent deep discharge on idle systems |
Zero-export stack
Configure this stack on export-limited sites. Work through the settings in order:| Setting | What it does |
|---|---|
| Solar Sell | Enables feed-in to the grid. Leave OFF for zero-export intent. |
| Max sell power | Caps feed-in power in watts when Solar Sell is on. Requires meter or CT. |
| Sell offset | Compensates for metering lag so the anti-backflow function never slightly over-sells. |
| Grid Peak-shaving | Caps grid draw at the set value; PV and battery supplement first; grid rises only if the load still exceeds the cap. Set to the site’s sanctioned load limit. |
Grid settings
Grid settings expose the safety-code selection and grid protection thresholds.- Confirm every safety-code selection with “Setting” → “OK” — the selection does not take effect without this confirmation step.
- The grid page exposes: connect and reconnect voltage/frequency windows and slopes, reconnection delay, power factor, 10-minute overvoltage threshold, and two-level OV/UV/OF/UF thresholds with detection times.
Advanced page (partner-gated unlock)
The Advanced page contains settings that require the partner-gated password. The page includes:- Parallel switch, number of parallel inverters, master/slave role
- Multi-inverter-one-pack option
- Feedback source selection
- Meter CT orientation and CT Ratio
- DRM enable
- NPE Relay Check and NPE voltage protection threshold
- GridSeamlessSwitch
- Insulation-protection enable
- Enclosure grounding test
- AFCI enable and clearance
If a setting you expect to find is not in this reference, check whether there is a KNB-VAL block on the relevant page — the setting is pending confirmation, not hidden.
Common mistakes
- Grid charging left at default OFF on a backup-first site — battery is empty at the first power cut.
- TOU slots that do not tile the full 24 hours — the linked boundaries fight back and the schedule behaves unexpectedly.
- “Solar Sell ON, Max sell power 0 W” configured without running the zero-export witness test. [KNB-VAL-07]
- Editing grid protection thresholds without utility consent or a Kent parameter sheet.
