Storage modes
Modes are exclusive — one at a time. Off-grid also engages automatically on a grid outage,
supplying backup loads only.
Mode options
Time of Use (TOU)
- Up to 6 charge + 6 discharge windows; each window sets a current (amperes) and a SOC/voltage cut-off, with an enable box per window. Available in Self-use and Selling first. Grid charges in charge windows only if Allow grid charging is ON.
Battery settings and functions
- Core thresholds: Max charge / discharge current, Overdischarge SOC (default 20 %), Recovery SOC, Force-charge SOC (default 10 %), Max charge SOC (default 100 %), Battery saving. Ordering rule: Force-charge < Overdischarge < Recovery.
- ECO function: with PV under 100 W and SOC below overdischarge, standby power comes from the grid, not the battery.
- Battery Healing: after long low-SOC operation, charges to the healing SOC before allowing discharge, restoring SOC accuracy.
Zero-export recipe (export-limited sites)
- Allow Export OFF (or Max export power = 0 where the DISCOM requires an explicit cap).
- Export calibration trimmed slightly negative if residual export shows.
- Witness test: high PV, minimum load, watch the utility meter for sustained export; then a heavy-load step for CT sign sanity. 📷
Only-PV-power-load (special cases)
OFF by default; auto-disabled when PV exceeds 510 V. If PV falls below the load, the load shuts and auto-restart retries after 3, then 5, then 10 minutes — after the third failure a manual reset is required. Know it exists before chasing a “mystery shutdown”.Common mistakes
- Feed-in “disabled” by hope instead of Allow Export OFF / Max export power 0 + witness test.
- TOU windows set in watts by M1 habit — this platform’s windows are current-based.
- Battery reserve dropped to 20 % “for more savings” — the first outage lands on an empty battery.
- Wake-up voltage typed from the manual text. [KNB-VAL-18]
