Advanced options¶
After configuring predictive charging, the wizard offers four additional optional steps that adjust the integration's behaviour in specific situations.
Weekly full charge¶
Forces a 100% charge once a week for cell balancing. You only need to select the day of the week.
See Weekly full charge for how it works.
Solar charge delay¶
Delays morning grid charging while the expected solar production can cover the required energy.
| Field | Description | Default |
|---|---|---|
| Safety margin | Minutes before sunset by which charging must be complete | 60 min |
| Solar forecast sensor | Only if not configured in the initial setup step | — |
A larger margin (e.g. 180 min) unlocks grid charging earlier in the day; a smaller margin waits longer for the sun to cover the energy.
See Solar charge delay for how it works.
Capacity protection (peak shaving)¶
Limits discharge when SOC drops below a threshold, covering only consumption peaks that exceed a configurable power limit.
| Field | Description | Default |
|---|---|---|
| SOC threshold | Protection activates below this % | 30 % |
| Peak power limit | Maximum consumption the battery covers; the excess falls to the grid | 2500 W |
See Peak shaving for how it works.
Advanced PD controller¶
Expert users only
Do not modify these values unless you understand PD control theory and how it interacts with inverter response times. Default values work correctly for the vast majority of installations.
Allows tuning the internal PD controller parameters. All values can also be adjusted at runtime from the integration's configuration entities without restarting.
| Parameter | Default | Range | Description |
|---|---|---|---|
| Kp | 0.65 |
0.1 – 2.0 | Proportional gain. Higher = faster response but more overshoot |
| Kd | 0.5 |
0.0 – 2.0 | Derivative gain. Higher = smoother transitions but slower response |
| Deadband | 40 W |
0 – 200 W | Dead zone. Controller does not act if the error is smaller than this value |
| Max power change | 800 W/cycle |
100 – 2000 W | Maximum change per cycle. Protects against abrupt swings |
| Direction hysteresis | 60 W |
0 – 200 W | Margin required to switch between charging and discharging |
| Min charge power | 0 W |
0 – 2000 W | If the controller calculates charge below this value, it stays idle. 0 = disabled |
| Min discharge power | 0 W |
0 – 2000 W | Same as above but for discharge. 0 = disabled |
The min charge/discharge power parameters are useful to prevent inefficient micro-cycling when grid demand is very low.
