Charging rules (priority order)

Each pipeline is evaluated top to bottom; the first matching rule wins. Full rate = 600 W. The fan gate is kept quiet unless overridden and can be adjusted in the control panel. Every B2500 (Marstek) SoC below is the usable % shown on the dashboard — the bottom 10% is never drawn, so the raw reading is ~10 points higher.

Charge setpoint — how many watts

Sets the desired Anker DC input the B2500 is steered toward. Every “solar” figure below is the rule value, not the raw PV meter: while the B2500 counts as full (≥98%, held until it drops below 95%) it can absorb nothing more, so the rules read solar as 800 W — its output ceiling. Displayed solar stays the raw meter reading.

S0 Feed switch off (see below) → no charge: B2500 idles at its floor.
S1 Manual DC max charge on → no limit (600 W), solar-only min(solar, 600 W), or the chosen watt cap.
S2 Carry-over active → full rate.
S11 Steer to safety → full rate. (B2500 >10% or solar array ≥400 W) and either (main >98% and expansion <20%) or main <20%.
S13 Anker main nearly empty (<15%) but B2500 also low (<5%) and solar >100 W → solar pass-through (no reserve left to pull).
S3 Anker main nearly empty (<15%) → full rate, pulling the B2500 reserve.
S14 B2500 full (≥98%, held until it drops below 95%) and expansion <80% → demand 1000 W and pin the device to Shelly mode — a full pack can absorb nothing more, so it is emptied wide open into the Anker.
S9 Load past the fan gate → match the load (fans already on, quiet cap dropped).
S4 B2500 low (<5%, stays on until it recovers to 10%) → solar pass-through only: min(load, solar), never draining its battery.
S5 B2500 surplus midday (12–19h, SoC above the main-scaled threshold) → full rate.
S10 Midday force-charge (12–19h, solar >300 W, B2500 >50%, expansion <20%) → B2500 max output.
S12 Night pre-charge (03–08h, B2500 >5%, expansion <80%) → load + 100 W from the B2500 (once per day, latched against bouncing).
S8 Expansion below band (<79%) → the higher of load + 20 W or all available solar (only the solar capped by the fan gate) — charges the Anker straight from solar instead of the lossy B2500.
S6 Expansion below band (<80%) → load + 20 W slow charge, under the fan gate.
S7 Expansion at/above band → match the load (neutral hold).

Feed switch — B2500 → Anker on/off

Gates the Solarpanel1 Shelly; only cut when we truly want zero charge.

F1 Manual DC max charge on → feed ON.
F2 Carry-over active → feed ON.
F3 B2500 bridge reading stale → hold last state; after 10 min default ON.
F0 Missing main/expansion SoC → hold last state.
F7 Steer to safety (same trigger as S11) → feed ON.
F4 Hand-off seam (main >95%, expansion <5%): expansion falling or B2500 >20% → ON; else OFF (do not strand).
F5 Expansion full (≥80%), no B2500 surplus, Anker not empty → feed OFF.
F6 Otherwise → feed ON (load-follow).
